How to pass two dimensional array to a function in c

#include <stdio.h>

#define M 3

#define N 5

void fstore2D(int a[][N]);

void fretrieve2D(int a[][N]);

int main(){

  int a[M][N];

  printf("Input data in matrix (%d X %d)\n", M, N);

  fstore2D(a);

  fretrieve2D(a);

  return 0;

}

void fstore2D(int a[][N]){

    int i, j;

    for (i = 0; i < M; ++i){

    for (j = 0; j < N; ++j)

         scanf("%d", &a[i][j]);

    }

}

void fretrieve2D(int a[][N]){

   int i, j;

   for ( i = 0; i < M; ++i ){

       for ( j = 0; j < N; ++j)

            printf("%6d ", a[i][j]);

       printf("\n");
