In C++, functions can use reference parameters to directly modify the arguments passed to them. A reference parameter is declared using the&symbol in the function signature. When a function is called with reference parameters, it operates directly on the variables passed as arguments, rather than ...
The parameters declared in the declarator of a function definition are in scope within the body. If a parameter is not used in the function body, it does not need to be named (it's sufficient to use an abstract declarator): void print(int a, int) // second parameter is not used { ...
Here are some examples of functions with different numbers of parameters: // This function takes no parameters // It does not rely on the caller for anything void doPrint() { std::cout << "In doPrint()\n"; } // This function takes one integer parameter named x // The caller will...
