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

Rather than use strlen as suggested above, you can just check for the NULL character:

#include 

int main(int argc, char *argv[])
{
    const char *const pszSource = "This is an example.";
    const char *pszChar = pszSource;

    while (pszChar != NULL && *pszChar != '\0')
    {
        printf("%s", *pszChar);
        ++pszChar;
    }

    getchar();

    return 0;
}
