I am trying to use #define to define a constant in my program. I realize I could use const, but I am trying to get a good understanding of #define. Could someone please explain why the following code does not work, and should be done instead?
#include <stdio.h> #define M 20; typedef int Marray_t[M][M]; //I can't define an M x M array int main() { Marray_t A; int i; for (i = 0; i < M; ++i) { //Can't iterate up to M A[i] = i; } return 0; }
