Program 129:To compare 2 Matrices

Program 126:
 

#include<stdio.h>
main()
{ 
 int i,j,rows_1,col_1,rows_2,col_2,flag=1;
 printf("Enter number of rows and columns of matrix 1\n");
 scanf("%d %d",&rows_1,&col_1);
 printf("Enter number of rows and columns of matrix 2\n");
 scanf("%d %d",&rows_2,&col_2);
 
 int a1[rows_1][col_1],a2[rows_2][col_2];
 
 if(rows_1==rows_2&&col_1==col_2)

     printf("Enter Matrix 1\n");
