C Program to Add Two Matrix

Question: Write a program in C to add two matrix having size M by N. Where M and N are given by user.

#include<stdio.h>

int main()
{
 int i,j,m,n;
 float a[10][10], b[10][10], sum[10][10];

 printf("Enter row and column size:\n");
 scanf("%d%d", &m, &n);
 
 printf("Enter elements of first matrix:\n");
 for(i=0;i< m;i++)
 {
  for(j=0;j< n;j++)
  {
   printf("a[%d][%d]=",i,j);
   scanf("%f", &a[i][j]);
  }
 }
 
 printf("Enter elements of second matrix:\n");
 for(i=0;i< m;i++)
 {
  for(j=0;j< n;j++)
  {
   printf("b[%d][%d]=",i,j);
   scanf("%f", &b[i][j]);
  }
 }
 
 for(i=0;i< m;i++)
 {
  for(j=0;j< n;j++)
  {
   sum[i][j] = a[i][j]+b[i][j];
  }
 }
 
 printf("Added matrix is:\n");
 for(i=0;i< m;i++)
 {
  for(j=0;j< n;j++)
  {
   printf("%f\t", sum[i][j]);
  }
  printf("\n");
 }
 return 0;
}
