Answer 1

if(str[i] == ' ')

Answer 2

You need to use single quotes for chars and double quotes for strings

Answer 3

An alternative, add cctype header;

#include <cctype>

Then, inside your loop, check for whitespace with std::isspace() to verify whether the said character is classified as a whitespace.

if(std::isspace(str[i])
// whitespace character
else
// non whitespace
