8.8 Lab: Swapping variables Write a program whose input is two integers and whose output is the two integers swapped. Ex: If the input is 3 8, then the output is 8 3 Your program must define and call a function. SwapValues returns the two values in swapped order. void SwapValues (int& userVal1, int& userVal2) zybooks c+ + g

Following are the program in c+ + language

#include / / header file

using namespace std; / / using namespace

void swapvalues (int& userVal1, int& userVal2); / / fucnction declaration

int main () / / main method

{

int x, y; / / variable declaration

cout<<"Enter the two value before swapping:/n";

cin>>x>>y; / / read the two input

cout<<"before swapping:";

cout<
swapvalues (x, y);

cout << "/nAfter swapping:";

cout<
return 0;

}

void swapvalues (int& userVal1, int& userVal2) / / function definition

{

int t; / / variable declaration

t = userVal1; / / assign the value userval1 to variable t

userVal1 = userVal2; / / assign the value userval2 to userval1

userVal2 = t; / / assign the value of variable t to userval2

}

Output:

Enter the two value before swapping:

3

8

before swapping:3 8

After swapping : 8 3

Explanation:

Following are the description of the program

Declared a variable "x" and "y" of type "int". Read a input by user in x and y. Display the values of variable x and y before the swapping. Call the function swapvalues () by passing the value of x and y. After calling the console moved In the definition of swapvalues () Function where it interchanged the value of variable userVal1 and userVal2 by using third variable "t". After interchanged the console moved to the main function and finally display the value of variable "x" and "y' after the swapping.
