Matrix Multiplication

Write a Program to enter two matrices and print their Product.

#include<iostream> using namespace std; int main() { int a[5][5],b[5][5],c[7][7],i,j,k,r1,c1,r2,c2; cout<<"Enter the order of first matrix:"; cin>>r1>>c1; cout<<"Enter the order of second matrix:"; cin>>r2>>c2; if(c1!=r2) { cout<<"Multiplication not possible.\n"; return 0; } cout<<"Enter the first matrix:\n"; for(i=0;i<r1;i++) for(j=0;j<c1;j++) cin>>a[i][j]; cout<<"Enter the second matrix:\n"; for(i=0;i<r2;i++) for(j=0;j<c2;j++) cin>>b[i][j]; for(i=0;i<r1;i++) for(j=0;j<c2;j++) c[i][j]=0; for(i=0;i<r1;i++) for(j=0;j<c2;j++) for(k=0;k<c1;k++) c[i][j]+=a[i][k]*b[k][j]; cout<<"The product matrix is:\n"; for(i=0;i<r1;i++) { for(j=0;j<c2;j++) cout<<c[i][j]<<" "; cout<<"\n"; } return 0; }
