Program 128:To get difference of 'N' Matrices

Program 128:
 
#include<stdio.h>
main()
{ 
 int i,j,rows,col,flag=1,x;
 printf("Enter number of rows\n");
 scanf("%d",&rows);
  printf("Enter number of columns\n");
 scanf("%d",&col);
 int a1[rows][col],a2[rows][col],diff[rows][col];
 //Taking input for 1st matrix
 printf("Enter Matrix 1\n");
 for(i=0;i<rows;i++)
 {
  for(j=0;j<col;j++)
  {
   scanf("%d",&a1[i][j]);
  }
 }
 do
 {
   //Taking input for 2nd matrix
  printf("Enter Matrix 2\n");
  for(i=0;i<rows;i++)
  {
  for(j=0;j<col;j++)
  {
   scanf("%d",&a2[i][j]);
  }
   }
    //Difference of matrix
   for(i=0;i<rows;i++)
   {
  for(j=0;j<col;j++)
