swapping of two numbers without using third variable in c

#include<stdio.h>
void main()
{
	int x = 10, y = 20;
    printf("Before swap x=%d y=%d",x,y);
    x=x+y;
    y=x-y;
    x=x-y;
    printf("
After swap x=%d y=%d",x,y);
}

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: 
");
    scanf("%d%d", &a, &b );
    printf("current values are:
 a=%d
 b=%d
", a, b);
    temp=a;
    a=b;
    b=temp;
    printf("After swapping:
 a=%d
 b=%d
", a, b);
}

C Programming to swap two variables

#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;

c program for swapping of two numbers

// Overcomplicating things lol. Try this
#include <stdio.h>
int main()
{
    int x, y;
    printf("Enter Value of x ");
    scanf("%d", &x);
    printf("
Enter Value of y ");
    scanf("%d", &y);
    int temp = x;
    x = y;
    y = temp;
    printf("
After Swapping: x = %d, y = %d", x, y);
    return 0;
