#include <stdio.h>

int main()
{
int x,y,z;
printf(“Enter two values: “);
scanf(“%d%d”,&x,&y);
z=x;
x=y;
y=z;
printf(“x=%d and y=%d”,x,y);
}

For Example:
If, x=5 and y=10

We put the value of x in z.
z=x
z=5

After that, we put the value of y in x.
x=y
x=10

Finally, we put the value of z in y.
y=z
so, y=5

And, Run the program to print x=10 and y=5
