QUOTE(nooc @ Nov 19 2004, 11:02 PM)  CODE #include <stdio.h> void fun(void) { #define fun() i=10 } int main() { int i = 20; fun(); printf("i = %d\n", i); return 0; } I think that this won't work : (i guess) we can't put preprocessor directives on a function If we can , it won't work also , because the compiler or the processor had completed the line : CODE fun(); so he won't replace it . if the preprocessor works in functions i guess this will be the answer CODE void fun(void) { #define printf("i = %d\n", i) i=0 } int main() { int i = 20; fun(); printf("i = %d\n", i); return 0; } What do you think ??? |

printf is a standard function in C. You can't modify it.
Try doing the same thing in c++. |
