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.
/* 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...
Write a program in C to swap two numbers using a function. C programming: swapping two variables Swapping two variables refers to mutually exchanging the values of the variables. Generally, this is done with the data in memory. The simplest method to swap two variables is to use a third te...
C Pointers C Pass Addresses and PointersProgram to Swap Elements Using Call by Reference #include <stdio.h> void cyclicSwap(int *a, int *b, int *c); int main() { int a, b, c; printf("Enter a, b and c respectively: "); scanf("%d %d %d", &a, &b, &c); printf("Value ...
C - Swap two numbers W/O using a temporary variable using C program? C - Read name & marital status of a girl & print her name with Miss or Mrs C - Check given number is divisible by A & B C - Find sum of all numbers from 0 to N W/O using loop C - Input hexadecimal valu...
1. Start the program. 2. Take two numbers as input. 3. Declare a function to swap two numbers which takes a pointer to a variable as parameter i.e any changes to variable in the function will be reflected everywhere. 4. Swap the two numbers inside the function using de-reference ...
Example 2: Swapping two numbers using Pointers This is one of the most popular example that shows how to swap numbers using call by reference. Try this program without pointers, you would see that the numbers are not swapped. The reason is same that we have seen above in the first example...
