Not reading the error messages from your compiler?

A little more explanation of where you feel you are having a problem will help us to help you.

Val

can you tell the input for which the output is coming wrong?
because when i tried N as 4, A as 1 and R as 2...
output came correct...

and in second line include has wrong spellings...it must be giving errors when compiled...
and one more thing please wrap code in code tags...

allright it worked but the page is disappearing i dont know why and i am righting getchar(0)
