Matrix Multiplication - The C++ Way

As I promised eariler I have now posted a Matrix Addition And Multiplication, this program is achived by passing an Object as an Argument..............

/* Matrix Multiplication by PASSING OBJECT AS AN ARGUMENT */

class Matrix
{
int A[10][10];
int m,n;
public:
Matrix(int a,int b)
{
m = a;
n = b;
}

void readmatrix();
void printmatrix();
void addmatrix(Matrix b);
Matrix operator * (Matrix b);
};
void Matrix::readmatrix()
{
for(int i=0;i< m;i++)
{
for(j=0;j< n;j++)
cin>>A[i][j];
}
}
}
void Matrix::printmatrix()
{
for(int i=0;i< m;i++)
{
for(int j=0;j< n;j++)
{
cout< < A[i][j]<<" ";
}
cout< < endl;
}
}
void Matrix::addmatrix(Matrix b)
{
Matrix c(m,n);
for(int i=0;i< m;i++)
{
for(int j=0;j< n;j++)
{
c.A[i][j]=A[i][j]+b.A[i][j];
}
}
cout< < "The Addition Of The Two Matrices Is:"< < endl; c.printmatrix();
}

Matrix Matrix::operator*(Matrix b)
{
Matrix c(m,m);
for(int i=0;i< m;i++)
{
for(int k=0;k< m;k++)
{
c.A[i][k]=0;
for(int j=0;j< n;j++)
{
c.A[i][k] = A[i][j] * b.A[j][k] + c.A[i][k];
}
}
}
return c;
}
void main()
{
clrscr();
cout< < "Enter Order The Two Square Matrices: " ;
int a;
cin>>a;

Matrix x(a,a);
Matrix y(a,a);

cout< < endl< < "Enter Elements In First Matrix : ";
x.readmatrix();

cout< < endl< < "Enter Elements In The Second Matrix :";
y.readmatrix();

cout< < endl< < "The First Matrix:"< < endl;
x.printmatrix();

cout< < endl< < "The Second Matrix:"< < endl;
y.printmatrix();
x.addmatrix(y);

Matrix c(a,a);
c = x * y;

cout< < "The Multiplication Of The Two Matrices Are:"< < endl;
c.printmatrix();
getch();
}

/****** OUTPUT *******

Operator Overloading,Inheritance

Here's a simple and also a very short program in C++ that makes use of Constructors, Operator Overloading (++,--)and Single Inheritance (cause its a simple program as I mentioned it).......


/* C++ Program For Implementation Of Constructors, Operator Overloading and Inheritance */

class index
{
protected:
int count;
public:
index()
{
count = 0;
}
index(int c)
{
count = c;
}
index operator ++()
{
count++;
}
void display()
{
cout< < endl< < "count = "< < count< < endl;
}
};

class index1 : public index
{
public:
void operator --()
{
count--;
}
};

void main()
{
clrscr();
index1 i;
i++;
i++;
i.display();
i--;
i.display();
getch();

Binary Tree Sort

This has two phases. First phase is creating a binary search tree using the given array elements. Second phase is traverse the given binary search tree in inorder, thus resulting in a sorted array.

Performance
The average number of comparisons for this method is O(nlog2n)
But in the worst case, the number of comparisons are reduced by O(n2), a case which arises when the sort tree is severely unbalanced .


/****** C Program For Implementation Of Binary Sort ***/

#define TRUE 1
#define FALSE 0

struct btreenode
{
struct btreenode *rightchild;
int data;
struct btreenode *leftchild;
};

insert(struct btreenode **sr,int num)
{
if(*sr==NULL)
{
*sr=malloc(sizeof(struct btreenode));

(*sr)- >leftchild=NULL;
(*sr)- >data=num;
(*sr)- >rightchild=NULL;
return;
}
else
{
if(num< (*sr)- >data)
insert(&((*sr)- >leftchild),num);
else
insert(&((*sr)- >rightchild),num);
}
return;
}

inorder(struct btreenode *sr)
{
if(sr!=NULL)
{
inorder(sr- >leftchild);
printf("%d ",sr- >data);
inorder(sr- >rightchild);
}
else
return;
}

postorder(struct btreenode *sr)
{
if(sr!=NULL)
{
postorder(sr- >rightchild);
printf("%d ",sr- >data);
postorder(sr- >leftchild);
}
else
return;
}

void main()
{
struct btreenode *bt;
int req,i=0,num,a[10],no;

bt=NULL;
clrscr();

while(i < 5)
{
printf("\nEnter value to be inserted: ");
scanf("%d",&a[i]);
insert(&bt,a[i]);
i++;
}
clrscr();
printf("\n\nSorted Binary tree in ascending order== > \n\n");
inorder(bt);
printf("\n\nSortred binary tree in descending order== >\n\n");
postorder(bt);
getch();
}

Straight Selection Sort

One of the easiest sorting methods is selection sort. Beginning with the first element of the given array, a search is made to find the largest element in the array. When the element is found this element is interchanged with the last element of the array. Now the size of the unsorted array will be reduced but one. A search for the largest element of the unsorted array is carried out. When this element is found it will be interchanged with the last element of the unsorted array. Once again the unsorted array will be reduced by 1 and the above process will be repeated till the entire array is sorted in ascending order.

ALGORITHM
1. Establish an array ‘a’ with ‘n’ elements
2. Repeat through step 6 for ‘n-1’ times
3. Repeat the position of the array already sorted
4. Repeat step 5 for the elements in unsorted position of the array
5. Record location of the largest element in the unsorted array
6. Exchange last element in the unsorted array with the largest element

PERFORMANCE OF THE ALGORITHM
During the first pass, in which the largest element is found, n-1 elements are compared. In general, for ith pass of the sort, n-I comparisons are required

So total number of comparisons
n-1 + n-2 + ……… + 1

Time Complexity = O(n2)

/**** C Program For Implementation Of Selection Sort ****/

#define MAX 10
char name[MAX][15];

{

char temp[15];
for(i=n;i >0;i--)
{
strcpy(temp,name[1]);
index=1;
for(j=1;j< =i;j++) { if(strcmp(name[j],temp) >0)
{
strcpy(temp,name[j]);
index=j;
}
}
strcpy(name[index],name[i]);
strcpy(name[i],temp);

Matrix Multiplication

Multiplication in C language is very useful, below is a simple example on matrix multiplication, later on i will post matrix arithematic operations using C++

#include<>
void main()
{
int a[10][10],b[10][10],c[10][10],i,j,k,m,n,p,q;
clrscr();

printf("Enter The Rows And Cloumns And Of The First Matrix:");
scanf("%d %d",&m,&n);
printf("\nEnter The Rows And Cloumns And Of The Second Matrix:");
scanf("%d %d",&p,&q);

printf("\nEnter Elements Of The First Matrix:\n");
for(i=0;i< m;i++)
{
for(j=0;j< n;j++)
scanf("%d",&a[i][j]);
}

printf("\nEnter Elements Of The Second Matrix:\n");
for(i=0;i< p;i++)
{
for(j=0;j< q;j++)
scanf("%d",&b[i][j]);
}
printf("The First Matrix Is:\n");
for(i=0;i< m;i++)
{
for(j=0;j< n;j++)
printf(" %d ",a[i][j]); //print the first matrix
printf("\n");
}
printf("The Second Matrix Is:\n");
for(i=0;i< p;i++) // print the second matrix
{
for(j=0;j< q;j++)
printf(" %d ",b[i][j]);
printf("\n");
}
if(n!=p)
{
printf("Aborting!!!!!!/nMultiplication Of The Above Matrices Not Possible.");
exit(0);
}
else
{
for(i=0;i< m;i++)
{
for(j=0;j< q;j++)
{
c[i][j] = 0;
for(k=0;k< n;k++)
{
c[i][j] = c[i][j] + a[i][k] * b[k][j];
}
}
}
printf("\nMultiplication Of The Above Two Matrices Are:\n\n");
for(i=0;i< m;i++)
{
for(j=0;j< q;j++)
{
printf(" %d ",c[i][j]);
}
printf("\n");
}
}
getch();
}

Merge Sort

Merging is the process of combining two or more sorted arrays into a third sorted array. We can use this technique to sort an array of n elements as follows.
Divide the array into ‘n’ sub arrays of size 1 and merge adjacent pairs of sub arrays. Then we can have approximately n/2 sorted sub arrays of size 2. Repeat this process until there is 1 array containing n elements.
Algorithm
1. Establish a sub array ‘a’ with n elements
2. Let size < - 1 3. Repeat steps 4 through 6 until size >= n
4. Subdivide the sub array into sub arrays of size ‘size’
5. Merge adjacent pairs of sub arrays
6. Double the size

/*** C Program For Implementation Of Merge Sort ***/

#define MAX 20

void mergesort(int *,int);
void main()
{
int x[MAX],n,j,i;

{
printf("Enter Element %d\t: ",i+1);
scanf("%d",&x[i]);
}
mergesort(x,n);
printf("\n\t│ Sorted Array :\t\t\t│\n\t│");
for(i=0;i< n;i++)
printf("%d\t",x[i]);
}
printf("│");
getch();
}

void mergesort(int x[],int n)
{
int sub[MAX];
int i,j,k,list1,list2,u1,u2,size=1;
while(size< n)
{
list1=0;
k=0;

while((list1+size)< n)
{
list2=list1+size;
u1=list2-1;
u2=((list2+size-1)< n)?(list2+size-1):(n-1);

for(i=list1,j=list2;i< =u1 &&amp;amp;amp; j< =u2;k++)
if(x[i]< =x[j])
sub[k]=x[i++];
else
sub[k]=x[j++];

}
for(i=list1;k< n;i++)

Circular Queue

A circular queue is a Queue but a particular implementation of a queue. It is very efficient. It is also quite useful in low level code, because insertion and deletion are totally independant, which means that you don't have to worry about an interrupt handler trying to do an insertion at the same time as your main code is doing a deletion.

Algorithm for Insertion:-
Step-1: If "rear" of the queue is pointing to the last position then go to step-2 or else step-3
Step-2: make the "rear" value as 0
Step-3: increment the "rear" value by one
Step-4:
  1. if the "front" points where "rear" is pointing and the queue holds a not NULL value for it, then its a "queue overflow" state, so quit; else go to step-4.2
  2. insert the new value for the queue position pointed by the "rear"
Algorithm for deletion:-
Step-1: If the queue is empty then say "empty queue" and quit; else continue
Step-2: Delete the "front" element
Step-3: If the "front" is pointing to the last position of the queue then step-4 else step-5
Step-4: Make the "front" point to the first position in the queue and quit
Step-5: Increment the "front" position by one


/****** C Program For Impelmetation Of Circular Queue *******/
#define MAX 5

Queue

A queue is a buffer abstract data structure providing services in computer science, transport and operations research where various entities such as data, objects, persons, or events are stored and held to be processed later. The most well known operation of the queue is the First-In-First-Out (FIFO) queue process. In a FIFO queue, the first element in the queue will be the first one out; this is equivalent to the requirement that whenever an element is added, all elements that were added before have to be removed before the new element can be invoked. Unless otherwise specified, the remainder of the article will refer to FIFO queues. There are also non-FIFO queue data structures, like priority queues.

Stack

One way to think about this implementation is to think of functions as being stacked on top of each other; the last one added to the stack is the first one taken off. In this way, the data structure itself enforces the proper order of calls. Conceptually, a stack is simple: a data structure that allows adding and removing elements in a particular order. Every time an element is added, it goes on the top of the stack; the only element that can be removed is the element that was at the top of the stack.

Consequently, a stack is said to have "first in last out" behavior (or "last in, first out"). The first item added to a stack will be the last item removed from a stack. So what's the big deal? Where do stacks come into play? As you've already seen, stacks are a useful way to organize our thoughts about how functions are called. In fact, the "call stack" is the term used for the list of functions either executing or watiing for other functions to return. In a sense, stacks are part of the fundamental language of computer science. When you want to express an idea of the "first in last out" variety, it just makes sense to talk about it using the common terminology. Moreover, such operations show up an awful lot, from theoretical computer science tools such as a push-down automaton to AI, including implementations of depth-first search.

Stacks have some useful terminology associated with them:

  1. Push To add an element to the stack
  2. Pop To remove an element from the stock
  3. Peek To look at elements in the stack without removing them
  4. LIFO Refers to the last in, first out behavior of the stack
  5. FILO Equivalent to LIFO
General Algorithm
  1. [Prologue] Save the parameters, Local Variables and return address.
  2. [Body] If the base criterion has been reached, then perform the final computation and go to step 3; otherwise, perfprm the partial computation and go to step 1(initialize a recursive call)
  3. [Epilogue] Restore the most recently saved parameters, local variables, and return address. Go to this return address.
