Question

I need to see if my string matches “hello X” where X is any int.

Basically I want to catch if its “hello 1” or “hello 100”.

How best can I do it?

Thanks Andrea Bergia.

I am using your code like this:

int dummy;
if (sscanf(string, "hello %d", &dummy))
    /* matched */

Answer 1

int dummy;
int n = sscanf(string, "hello %d", &dummy);
if (n == 1) {
    // Matched
}
