Of all the offbeat replies in this thread, this has to be the most ridiculous - While we are at it, why don't we also add the GETPRICE.h library, then our code would be as simple as:

#include <stdio.h>
#include <GETPRICE.h>

int main(int argc, int *argv[]) {
    PRICE *p;
    if (init_price(p, "file") != 0)
        return 1;

    printf("The price of an apple is %s\n", get_price(p, "apple"));
    destroy_price(p);
    return 0;
}

The summary of this thread should simply be - C and Perl are different, get over it.
