How to swap two numbers
// Method 1: With temporary variable
temp = A
A = B
B = temp
// without temporary variable
// Method 2: Addition and subtraction
A = A + B
B = A - B
A = A - B
// Method 3: Muitply and Divide
A = A * B
B = A / B
A = A / BHow to swap two numbers
// Method 1: With temporary variable
temp = A
A = B
B = temp
// without temporary variable
// Method 2: Addition and subtraction
A = A + B
B = A - B
A = A - B
// Method 3: Muitply and Divide
A = A * B
B = A / B
A = A / Bhow to swap values in variables in c
#include <stdio.h>
#include <stdlib.h>
int main()
{
//initialize variables
int num1 = 10;
int num2 = 9;
int tmp;
//create the variables needed to store the address of the variables
//that we want to swap values
int *p_num1 = &num1;
int *p_num2 = &num2;
//print what the values are before the swap
printf("num1: %i\n", num1);
printf("num2: %i\n", num2);
//store one of the variables in tmp so we can access it later
//gives the value we stored in another variable the new value
//give the other variable the value of tmp
tmp = num1;
*p_num1 = num2;
*p_num2 = tmp;
//print the values after swap has occured
printf("num1: %i\n", num1);
printf("num2: %i\n", num2);
return 0;
}Write a program to show swap of two numbers without using third variable.
#include<stdio.h>
int main()
{
int a=10, b=20;
printf("Before swap a=%d b=%d",a,b);
a=a+b;//a=30 (10+20)
b=a-b;//b=10 (30-20)
a=a-b;//a=20 (30-10)
printf("\nAfter swap a=%d b=%d",a,b);
return 0;
}program to swap two numbers
#include<stdio.h>
int main()
{
int x = 20, y = 30, temp;
temp = x;
x = y;
y = temp;
printf("X = %d and Y = %d", x, y);
return 0;
