std string length and size member functions

0 votes
While reading the responses to this topic, I discovered that although I always used size(), there is a function for std::string called length().

Is there a reason this function exists in the std::string class?

According to what I've read in MSDN and CppReference, there is no distinction between size() and length ().

If that's the case, doesn't it only make things more complicated for class users?

functions in c++ call by value and call by reference

Calling a function by value copies the argument and stores it in a local variable for use by the function, so the argument is unaffected if the value of the local variable changes.  The argument is passed to the function as a reference rather than a copy, so if the function changes the value of the argument, the argument is also changed.   The void change(int); function prototype informs the compiler that there is a function named change that takes a single int argument and returns void (i.e. nothing).  Because there is no & with the argument, it is called by value.  You have the line change(orig); later in your code, which actually calls the function with. Take a look at the output of ...READ MORE
