c code to swap two numbers code example
Example 1: swap two numbers in c
#include <stdio.h>
int main() {
double a, b;
printf("Enter a: ");
scanf("%lf", &a);
printf("Enter b: ");
scanf("%lf", &b);
a = a - b;
b = a + b;
a = b - a;
printf("After swapping, a = %.2lf\n", a);
printf("After swapping, b = %.2lf", b);
return 0;
}
Example 2: c program for swapping of two numbers using temporary variable
#include <stdio.h>
int main()
{
int a, b, temp;
printf("enter the values of a and b: \n");
scanf("%d%d", &a, &b );
printf("current values are:\n a=%d\n b=%d\n", a, b);
temp=a;
a=b;
b=temp;
printf("After swapping:\n a=%d\n b=%d\n", a, b);
}
