C program to Swap two numbers
- Swapping means Interchanging.
- To swap we need to declare a third variable which is an temporary variable.
- For example: you have taken two variables a and b where a = 4 and b = 5, then before swapping a = 4, b = 5 after swapping a = 5, b = 4.
Sample Code
#include <stdio.h>
int main()
{
int a=10,b=12,temp;
printf("\na =10 ");
printf("\nb =12 ");
temp=a;
a=b;
b=temp;
printf("\na = %d\tb = %d \n", a, b);
}
Output
a =10
b =12
a = 12 b = 10
