Problem Statement

luc052.c

If a macro is not getting expanded as per your expectation, how will you find out how is it being expanded by the preprocessor?

Source Code

#include <stdio.h>
#include <math.h>
#include <stdlib.h>

int main()
{
    printf("To see how macros are expanded, use the compiler flag '-E'.\n");
    printf("Command: gcc -E filename.c\n");
    printf("This outputs the file after preprocessing stage.\n");

    return 0;
}
