So textual replacement of clrscr() to 100 occurs.The input program to compiler looks like this : main() { 100; printf("%d\n",100); } Note: Line 1: 100; is an executable statement but with no action. So it doesn't give any problem Answer: 100   #89581    Author: Deepakkumar Devarajan      Member Level: Gold      Member Rank: 0     Date: 08/Jun/2009   Rating:     Points: 0 Malathi, I have not seen the preprocessor statement :-) so i thought clrscr() is a predefined function. Well , keep posting questions like this, it'll make us to use our Brain.
