Largest and second largest of all rows and columns of a matrix.

This is a C program to find the largest and second largest element of all the rows and columns of a matrix. If you have any doubts, please feel free in asking.

#include<stdio.h>

main()

 int a[50][50],size,n,m,i,j,large,slarge;

 for(i=0;i<n;i++)

 {

  for(j=0;j<m;j++)

   scanf("%d",&a[i][j]);

 }

 printf("\n the inputed matrix is:\n");

 for(i=0;i<n;i++)
