I am afraid i understood the question. If the question is
defined like, u need to exchange two variables without using
a temporary variable is,

a += b;
b = a - b;
a = a - b;
Another methos is ,
a ^= b ^= a ^= b;

#include show(int t,va_list ptr1) { int a,x,i; a=va_arg(ptr1,int) printf(" %d",a) } display(char) { int x; listptr; va_star(otr,s); n=va_arg(ptr,int); show(x,ptr); } main() { display("hello",4,12,13,14,44); }
