Question

For example, I have the following code:

#define MAX_CLIENTS 100;

void main() {
    char* pick[MAX_CLIENTS];
    int* points[MAX_CLIENTS];
    return 0;
}

Trying to compile it throws these errors:

file.c:4: error: expected ‘]’ before ‘;’ token
file.c:5: error: expected ‘]’ before ‘;’ token

If I replace MAX_CLIENTS in the subscripts with a literal 100, then the errors are gone.

Why?

Answer 1

the ; in #define MAX_CLIENTS 100; is redundant , remove it and you should be fine.

Remember that #define is a pre-processor command, that replaces MAX_CLIENTS with 100; – you don’t want the semicolon there, only the 100.
