Alternatively, you can usefindto compare specific character ranges in two strings. To do this, you should pass the starting position and length of the range as arguments to thefindmethod: #include<iostream>#include<string>using std::cin;using std::cout;using std::endl using std::string;using...
The idea is to use theindexOf()method of theStringclass, which returns the index within this string of the first occurrence of the specified substring, starting at the specified index. It returns-1if there is no such occurrence. The trick is to start from the position where the last foun...
