Here's a start:

#define PRINT(a, n) do {     \
    int i;                   \
    for (i = 0; ?; ?) {      \
        ?                    \
    }                        \
} while(0)

Note the do { ... } while(0) structure around the macro, it is very educational.

#include<stdio.h>
#define PRINTARRAY(array, length) \
for(int i = 0; i < length; i++) \
    printf("%d\t", array[i]);

int main(void) {
    int array[5] = {4, 2, 3, 1, 0};
    PRINTARRAY(array, 5);
    return 0;
}
