Run Code Output Enter first number: 1.20 Enter second number: 2.45 After swapping, first number = 2.45 After swapping, second number = 1.20 In the above program, the temp variable is assigned the value of the first variable. Then, the value of the first variable is assigned to the se...
The simplest method to swap two variables is to use a third temporary variable : define swap(a, b) temp := a a := b b := temp Pictorial Presentation: Sample Solution: C Code: #include<stdio.h>voidswap(int*,int*);intmain(){intn1,n2;printf("\n\n Function : swap two numbers us...
/* C program to swap two integers using bitwise operators */#include <stdio.h>intmain(){intn1=5,n2=7;printf("Before swap: n1: %d\tn2: %d\n",n1,n2);n1=n1^n2;n2=n1^n2;n1=n1^n2;printf("After swap: n1: %d\tn2: %d\n",n1,n2);return0;}OUTPUT===Before swap:n1:5n2:7Aft...
In this C Programming example, we will discuss how to swap two numbers using the pointers in C and also discuss the execution and pseudocode in detail.
Given two integer numbers "a" and "b" and we have to swap their values without using any temporary variable.ExampleInput: a=10, b=20 Output: a=20, b=10 Logic to swap number using temporary variableIn this program, we are writing code that will swap numbers without using other variable...
Swapping of two numbers in C Language is the process in which the value of two variables is exchanged using some code. For example,a = 5, b = 4 // After swapping: a = 4, b = 5We can swap two numbers in various ways as follows:Swapping two variable values using a Temporary ...
With the program on the left, no swapping took place. The values ofaandbare passed toswap, and the function does swap them, but when the function returns, nothing has changed in themain To get an idea of what this code does, print it out, draw the two integersaandb, and enter23and...
