int len = str.length()

Answer 2

Choose either one, a little note, all three are unsigned integer types. Where `auto` means compiler deduce the type of <len>.

std::string::size_type len {your_string.size()};

Or

std::size_t len {your_string.size()};

Or

auto len {your_string.size()};

Answer 3

#include<string.h>

...
int i = strlen(your string);
