UsefindMethod to Find Substring in a String in C++ The most straightforward way of solving the issue is thefindfunction, which is a built-instringmethod, and it takes anotherstringobject as an argument. #include<iostream>#include<string>using std::cin;using std::cout;using std::endl using ...
If the substring is found, the function returns the position of the first found substring. This position is the position of a character where the substring starts in the main string. If the substring is not found, the function returns a value that is std::string::npos. The function itself...

值得注意的是for循环中用到了强制类型转换,cpp中string.size()返回类型是unsign ed int,无符号数,无符号数与有符号数运算时,有符号数被转换成无符号数进行运算,当s.size() < size * len时,s.size() - size*len结果为负数,unsigned转换后变为一个极大值UMAX-abs(s.size()-size*len),导致越界出错,所以...
