two ways to swap a number....
1st method
main()
{
int a,b;
printf("enter two numbers for swaping");
scanf("%d%d",&a,&b);
a=a+b;
b=a-b;
a=a-b;
printf("a=%d,b=%d",a,b)
getch()
}

2nd method
main()
{
int a,b;
printf("enter two numbers for swaping");
scanf("%d%d",&a,&b);
a=a*b;
b=a/b;
a=a/b;
printf("a=%d,b=%d",a,b)
getch()
}
