Splet17. maj 2016 · At least you should think like this to swap them: temp = num1 num1 = num2 num2 = temp and because C++ will just pass value to function if you declare like this void swap (int num1, int num2) so you need to use pointer or reference to do it (the detail implementation could be searched easily): SpletQ. Write a C++ program to swap two numbers using call-by-reference method. Answer: Call-by-reference is a location or address of actual arguments passed to formal arguments. Following program shows that the swapping of two numbers using call-by-reference. #include using namespace std;

There are two methods to solve this problem with the help of functions, and there are two methods to do this the first is Call By Value and Call by Reference. SpletTo pass the value by reference, argument reference is passed to the functions just like any other value. So accordingly you need to declare the function parameters as reference types as in the following function swap (), which exchanges the values of the two integer variables pointed to by its arguments. myjcb カード追加できない
