what is -> in c++
/**
* @author Charles Salvia (StackOverflow)
*
* -> is to access a member function or member variable of an object through
* a pointer, as opposed to a regular variable or reference.
*/
// For example: with a regular variable or reference, you use the . operator
// to access member functions or member variables.
std::string s = "abc";
std::cout << s.length() << std::endl;
//But if you're working with a pointer, you need to use the -> operator:
std::string* s = new std::string("abc");
std::cout << s->length() << std::endl;
Are there any code examples left?
