I wrote a little program that returns true if a string is contained in another string, otherwise returns false. https://code.sololearn.com/cgq4kWNa9g7L/#cpp

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/

Do you mean find a string that is contained in another string?
