How to iterate over a string in C?

Question

Right now I\'m trying this:

#include 

int main(int argc, char *argv[]) {

    if (argc != 3) {

        printf(\"Usage: %s %s sourcecode inpu         


        

Answer 1

• sizeof(source) is returning to you the size of a char*, not the length of the string. You should be using strlen(source), and you should move that out of the loop, or else you'll be recalculating the size of the string every loop.
• By printing with the %s format modifier, printf is looking for a char*, but you're actually passing a char. You should use the %c modifier.
