Parentheses can't be used to enclose statements. What you want is:

#define hello() printf("Hello");

The semicolon is also unnecessary, or maybe you meant:

#define hello() { printf("Hello"); }

Aside from that syntax error, you should probably include cstdio to use printf, and main should return int.
