In this article, we are going to discuss how to swap two numbers by using the function or without a function. So let’s start!<\/p>\n
There are two ways to swap the number one is by using a third variable and another by adding or subtracting the values in it. So we going to discuss them one by one.<\/p>\n
\/\/ C program to swap two numbers by using the function<\/p>\n
#include<stdio.h>
\nint swap(int x, int y){
\nint temp =x;
\nx = y;
\ny = temp;
\n}<\/p>\n
int main(){
\nint x, y;
\nprintf(“Enter the value of x :”);
\nscanf(“%d”, &x);
\nprintf(“Enter the value of y :”);
\nscanf(“%d”, &y);
\nswap(x,y);
\nprintf(“After swapping the number are x=%d y=%d”,x,y);
\nreturn 0;
\n}<\/p>\n
output :<\/strong><\/p>\n Enter the value of x:22 Step 1:<\/strong> First create a user-defined function and pass two parameters in it.<\/p>\n Step 2:<\/strong> After passing the argument we simply use the third variable in it and give the name as temp then we simply do \u2013 int temp =x; Step 3:<\/strong> After this, we simply go for the main method, and then simply we create two int-type variables to get input from the user.<\/p>\n Step 4:<\/strong> After that, we simply use scanf() to store the value of a variable.<\/p>\n Step 5:<\/strong> then we simply swap(x,y).<\/p>\n step 6:<\/strong> after the above steps we simply use printf() to get our desired output.<\/p>\n #include<stdio.h> Output<\/strong><\/p>\n Enter a value for num1:22 Step 1:<\/strong> First we take the int type variable to get input from user. And then also we use int type temp variable to store the value of x in it.<\/p>\n Step 2:<\/strong> After getting we simply use scanf() to store the value of variables.<\/p>\n Step 3:<\/strong> then we simply swap two variables such as temp = num1; Step 4:<\/strong> After that, we simply use printf() to print our desired output.<\/p>\n \/\/ C program to swap two numbers without using a third variable.<\/p>\n #include<stdio.h> Output<\/strong><\/p>\n Enter a value for num1:22 Enter a value for num1:22 Step 1:<\/strong> First we take the int type variable to get input from the user.<\/p>\n Step 2:<\/strong> After getting we simply use scanf() to store the value of variables.<\/p>\n Step 3:<\/strong> then we simply swap two variables such as num1 = num1 + num2; Step 4:<\/strong> After that, we simply use printf() to print our desired output.<\/p>\n In this way, we simply understand how we swap two numbers by using these three methods. I hope this thing is clear to you. So for now keep learning and keep exploring.<\/p>\n","protected":false},"excerpt":{"rendered":" In this article, we are going to discuss how to swap two numbers by using the function or without a function.
