Question
Hi! This is my first semester programming and I have homework assignemt. Assignment is I need to write a program to do matrix multiplication (limit a program to 3*3) and I have to draw a structure chart. Can you please help me! Thank you so much.

Answer
Hai Dear Ravi!

Here is the programme what actually you are looking for !

#include <iostream.h>
int main()
{
  int a[3][3] , b[3][3] , c[3][3];
  int i , j , k;

  cout<<"Enter A matrix ";
  for( i = 0 ; i < 3 ; i++)
     for( j = 0 ; j < 3 ; j++)
        cin>> a[i][j];
  cout<<"Enter B matrix ";
  for( i = 0 ; i < 3 ; i++)
     for( j = 0 ; j < 3 ; j++)
        cin>>b[i][j];
  for( i = 0 ; i < 3 ; i++)
  {
     for( j = 0; j < 3 ; j++)
     {
        c[i][j] = 0;
        for( k = 0 ; k < 3 ; k++)
         c[i][j] += a[i][k]*b[k][j];
     }
  }
  cout<<"The resultant matrix is : ";
  for( i = 0 ; i < 3 ; i++)
  {
     for( j = 0 ; j < 3 ; j++)
        cout<<c[i][j];
     cout<<"\n";
  }
     return 0;

}

In order to draw th structure chart , you should be familiar with the notations used in  the structure chart , so i kindly request you to visit the following link to understand the notations !
