G-Fact 16
Predict the output of following program.
#include <stdio.h> int main() { int x = 012; printf("%d", x); getchar(); return 0; } |

The program prints 10. Putting a 0 before an integer constant makes it an octal number and putting 0x (or 0X) makes it a hexadecimal number. It is easy to put a 0 by accident, or as a habit. The mistake is very common with beginners.
