c++ compiler configuration

#include <iostream>
#include <algorithm>
#include <string>

int main()
{
std::string s = "This is an example";
std::cout << s << '\n';

s.erase(0, 5); // Erase "This "
std::cout << s << '\n';

s.erase(std::find(s.begin(), s.end(), ' ')); // Erase ' '
std::cout << s << '\n';

s.erase(s.find(' ')); // Trim from ' ' to the end of the string
std::cout << s << '\n';
}

Output:
