Without using 3rd 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;
}
with using 3rd variable
#include<stdio.h>
int main() {
double first, second, temp;
printf("Enter first number: ");
scanf("%lf", &first);
printf("Enter second number: ");
scanf("%lf", &second);
// Value of first is assigned to temp
temp = first;
// Value of second is assigned to first
first = second;
// Value of temp (initial value of first) is assigned to second
second = temp;
printf("\nAfter swapping, firstNumber = %.2lf\n", first);
printf("After swapping, secondNumber = %.2lf", second);
return 0;
