Why would you not use;

a=x(1)
x(1)=x(2)
x(2)=a

?

ok I am completely blank..
if i have to arrange these number(10,4,1)into ascending order..
what should i do..

Run through each number (to n-1) in the list (of n numbers) and swap over any where x(a) > x(a+1). Repeat. Set up a flag so you can stop if none are swapped during a repeat.
