Answer 2

The String class has a find method that searches for the string passed as a parameter, if the string is found returns the position of the first letter of the first match.
If the substring is not found the method returns string::npos.

if(str.find(substring) != string::npos) { return true; }

The line above means that if the string is found do some code.

More info about the find method here: http://www.cplusplus.com/reference/string/string/find/
