Passing Multi-dimensional Arrays to Function

To pass a two-dimensional array to a function as an argument, starting address of the memory area reserved is passed as in a one dimensional array.

Example Program:

Pass two-dimensional arrays to a function.

#include <stdio.h>
void displayNumbers(int num[2][2]);
int main()
{
int num[2][2], i, j;
printf("Enter 4 numbers:\n");
for (i = 0; i< 2; ++i)
for (j = 0; j < 2; ++j)
scanf("%d", &num[i][j]);// passing multi-dimensional array to displayNumbers function
displayNumbers(num);
return 0;
}
void displayNumbers(int num[2][2])
{
int i, j;
printf("Displaying:\n");
for (i = 0; i< 2; ++i)
for (j = 0; j < 2; ++j)
printf("%d\n", num[i][j]);
}
