c++ - Metaprogramming via macro -


i’d same stuff can d’s mixins c/c++ preprocessor. i’d write function generate parameter list. instance:

#define mk_fn_foo(n,t) …  mk_fn_foo(3,float)  /* expand */ void foo(float x0, float x1, float x2) {     /* else here */ }

i have idea i’m facing issue. have recursion , have no idea how such thing:

#define mk_foo(n,t) void foo(mk_foo_plist(n-1,t)) { } #define mk_foo_plist(n,t) t xn, mk_foo_plist(n-1,t) /* how stop that?! */

the boost libraries have vast extensive metaprogramming , else preprocessor library. possible kind of thing using utility preprocessor directives easier doing yourself, although still confusing :)

i suggest start there:

http://www.boost.org/doc/libs/1_53_0/libs/preprocessor/doc/index.html

http://www.boost.org/doc/libs/?view=category_preprocessor

edit: here tutorial them: boost.preprocessor - tutorial

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua...
