Array subtraction in Two-Dimensional Array using Array in C

This program is written in C programming language and it does the following:

It first declares some integer variables r, c, a, b, i, j and a third 2D array 't'
The program then prompts the user to enter the row and column limits 'r' and 'c' respectively, which determines the size of two 2D arrays 'a' and 'b'
Then, it prompts the user to enter values for the two 2D arrays 'a' and 'b' using nested for loop
Next, it uses another nested for loop to iterate through both arrays 'a' and 'b' and performs subtraction of corresponding elements of both arrays and stores the result in another array 't'
The program then uses another nested for loop to print the values of the 't' array
The values of the subtraction are displayed in tabular format
The program ends by returning 0 as the value of the main function

int main()
{
  int r,c,a[10][10],i,j,b[10][10],t[10][10];
  printf("\nEnter the row limit:");
  scanf("%d",&r);
  printf("\nEnter the column limit:");
  scanf("%d",&c);
  printf("\nEnter the first matrix:");
  for(i=0;i<r;i++)
  {
    for(j=0;j<c;j++)
    {
       scanf("%d",&a[i][j]);
    }
  }
  printf("\nEnter the second matrix:");
  for(i=0;i<r;i++)
  {
    for(j=0;j<c;j++)
    {
       scanf("%d",&b[i][j]);
    }
  }
  for(i=0;i<r;i++)
  {
    for(j=0;j<c;j++)
    {
      t[i][j]=a[i][j]-b[i][j];
    }
  }
  printf("\nTotal value is:\n");
  for(i=0;i<r;i++)
  {
    for(j=0;j<c;j++)
    {
      printf(" %d",t[i][j]);
    }
    printf("\n");
  }
  return 0;
