#include \"header.h\"\n<\/code><\/pre>\n
This is replaced by the compiler with the code of header.h<\/code>. <\/p>\n
#define header\n<\/code><\/pre>\n
This just defines a ‘mark’ (not sure how to call it). It can be used in some code like that<\/p>\n
#ifdef header \n    puts(\"It is defined!\");\n#else\n    puts(\"Oh no!\");\n#endif\n<\/code><\/pre>\n
The underscores can be used in a variable’s names and also in the defines. They don’t have any meaning except the fact that many functions used in system libraries start with an underscore. So, writing a function called _exit<\/code> will lead to lots of problems as there is an important system call called like this. <\/p>\n
If define<\/code> works like include<\/code> in your case, than I can guess your compiler’s drunk or you have #include \"header.h\"<\/code> somewhere else in your code. <\/p>\n<\/p><\/div>\n
