C++ program for matrix multiplication

//c++ program to multiply two matrices (max 6x6 size *here)

#include<iostream.h>

#include<conio.h>

int main()

{

clrscr();

int r1,r2,c1,c2,a[6][6],b[6][6],c[6][6],i,j; //size of array can be changed

cout<<”Enter the number of rows and columns of first matrix\n”;

cin>>r1>>c1;

cout<<”Enter the number of rows and columns of second matrix\n”;

cin>>r2>>c2;

if (c1!=r2)

                cout<<”\n matrix multiplication is not possible”;

else

                {

                cout<<”\n matrix multiplication is possible”;

                cout<<”\nEnter the elements in first matrix row wise\n”;

                for(i=0;i<r1;++i)

                                {

                                for(j=0;j<c1;++j)

                                                cin>>a[i][j];

             }

                cout<<”\nEnter the elements in second matrix row wise\n”;

                for(i=0;i<r2;++i)

                                {

                                for(j=0;j<c2;++j)

                                                cin>>b[i][j];

             }

                cout<<”\nThe result is\n”;

                for(i=0;i<r1;++i)

                                {

                                for (j=0;j<c2;++j)

                                                {

                                                c[i][j]=0;

                                                For(int k=0;k<c1;++k)

                                                                c[i][j]+=(a[i][k]*b[k][j]);

                     }

              }

                for(i=0;i<r1;++i)

                                {

                                for(j=0;j<c2;++j)

                                                cout<<c[i][j];<<”\t”;

                                cout<<”\n”;

              }

}

getch();

return0;
