Swapping of two numbers in c
#include <stdio.h>
#include <conio.h>
void main()
{
int x, y, temp;
printf("Enter the value of x and y\n");
scanf("%d%d", &x, &y);
printf("Before Swapping\nx = %d\ny = %d\n",x,y);
temp = x;
x = y;
y = temp;
printf("After Swapping\nx = %d\ny = %d\n",x,y);
getch();
}
Output:
Enter the value of x and y
9
7
Before Swapping x= 9
y= 7
After swapping x= 7
y=9
Swapping of two numbers without third variable
#include <stdio.h>
#include <conio.h>
void main()
{
int a, b;
printf("Enter two integers to swap\n");
scanf("%d%d", &a, &b);
a = a + b;
b = a - b;
a = a - b;
printf("a = %d\nb = %d\n",a,b);
getch();
}
Output:
Enter two integers to swap
9
7
a=7
b=9
