#include<stdio.h>

# define rows [3]
# define cols [3]
void input(int arr2d[][cols]);
void print (int arr2d[][cols]);
void add (int mat1[][cols],int mat2[][cols],int result[][cols]);
int result[][cols];
void main(void)

}
}
void print(int arr2d[][cols]

}

Answer 1

Firstly, please indent your code. It is not hard and really helps for readability. Next, you probably meant:

#define rows 3
#define cols 3

Next, this line is wrong:

printf("element [%d][%d]=%d",i,j,arr2d[i][j];  // you need a )

and

void add(int num1[][cols],int mat2[][cols],int result[][cols];  // same problem

There are probably other problems in your code, but just make these corrections for now. Also, can you actually post the compiler errors you are getting.
