## How do you exchange a value with two variables?

The bitwise XOR operator can be used to swap two variables. The XOR of two numbers x and y returns a number that has all the bits as 1 wherever bits of x and y differ. For example, XOR of 10 (In Binary 1010) and 5 (In Binary 0101) is 1111 and XOR of 7 (0111) and 5 (0101) is (0010).

### How do you swap two numbers in a function?

C Program to Swap two Numbers

1. Assign x to a temp variable : temp = x.
2. Assign y to x : x = y.
3. Assign temp to y : y = temp.

How do you swap values?

In computer programming, the act of swapping two variables refers to mutually exchanging the values of the variables. Usually, this is done with the data in memory. For example, in a program, two variables may be defined thus (in pseudocode): data_item x := 1 data_item y := 0 swap (x, y);

What is meant by swapping?

Swapping refers to the exchange of two or more things. For example, in programming data may be swapped between two variables, or things may be swapped between two people.

## How do you swap arrays?

A simple solution is to iterate over elements of both arrays and swap them one by one. A quick solution is to use std::swap(). It can directly swap arrays if they are of same size.

### How do you swap numbers in an array in C++?

The C++ function std::array::swaps() swap contents of the array. This method takes other array as parameter and exchage contents of the both arrays in linear fashion by performing swap operation on induvisual element of array.

How to exchange values of two variables in C + +?

C++ program to exchange values of two variables (Swapping) using pointer. This program uses a function called exchange(int*,int*) that takes two argument as integer pointers. The variables are passed by reference method and hence, the swapping done at the exchange function will reflect in the main method also. #include . #include .

How to exchange two numbers using function-c?

Exchange two numbers using Function – C. Write a function to exchange the values of two variables say x and y. Assume x and y are defined as global variables.

## Do you have to return values to exchange function?

The variables are passed by reference method and hence, the swapping done at the exchange function will reflect in the main method also. //No need to return any values since the variables are already affected.

### How to exchange private values of two classes?

Q. Write a C++ program to demonstrate how a common friend function can be used to exchange the private values of two classes. (Use call by reference method). Following program is demonstrating how a common friend function can be used to exchange the private values of two classes using call-by-reference method.
