Question

I’m having issues writing a C function that reads a string from STDIN, and returns the length of said string… Suggestions?

Answer 1

So, simply use strlen from the C standard library:

#include <string.h>

So the strlen() function is available. You just need to pass a char pointer, and it will return the string length:

size_t length = strlen( myStr );

Note that size_t is an integral type.

By the way, if you don’t know about this function, you should really dig into the C library, and lear about the basic functions it provides.
