String types c++
WebA string is a class that contains a char array, but automatically manages it for you. Most string implementations have a built-in array of 16 characters (so short strings don't fragment the heap) and use the heap for longer strings. You can access a string's char array like this: WebConverting constructor. A constructor that is not declared with the specifier explicit and which can be called with a single parameter (until C++11) is called a converting …

By iterating through the characters in the string and counting them until it reaches the null character '\0', the function returns the length of the string as a size_t value. While strlen () is a useful tool for working with C ...
