Multiplication of Two Matrices

Non-Recursive C Program:

Aim: Two print matrix multiplication.

Program:
#include <stdio.h>
#include <conio.h>
void main()
  { 
   int A[10][10], B[10][10],mat[10][10], i, j,k, R1,C1,R2,C2;
clrscr();
printf("Enter the order of the matrice A \n");
scanf("%d %d", &R1, &C1);
printf("Enter the order of the matrice B \n");
scanf("%d %d", &R2, &C2);
if(C1==R2)
{
printf("Enter the elements of  matrix A\n");
for(i=0; i<R1; i++)
   {   for(j=0; j<C1; j++)
       {
          scanf("%d",&A[i][j]);
       }
   }

printf("MATRIX A is\n");
   for(i=0; i<R1; i++)
     { for(j=0; j<C1; j++)
          {
              printf("%3d",A[i][j]);
