Answer 1

You have an error, it reads characters into a string up to the first space. To read the entire string, including spaces, you need to use your second mistake in that it returns not the length of the string, but the size of the type . To get the length of a particular string, you need to use or And, finally, you don't need a string. Delete it. std::cin>>s
#include <cstring>

Answer 2

sizeof(s)

if you need the size of the string, then s.size()
