c++ - 'Input' does not name a type error. Can't figure out why? -

when compile, error: 'input' not name type on line 17

#ifndef game_h #define game_h  #include "input.h"  // can forward declare "class input(glfwwindow*);" here still //     gives same error.  class game {     public:         game(input* input);         ~game();          void input();         void update();         void render();      private:         input* mpinput; //error here. };  #endif // game_h 

input.h looks this.

#ifndef input_h #define input_h  #include <glfw/glfw3.h> #include <vector>  class input {     public:         input(glfwwindow* window);         ~input();         bool getkey(int keycode);         bool getkeydown(int keycode);         bool getkeyup(int keycode);         void update();      private:         glfwwindow* mpwindow;         std::vector<bool> mcurrentkeys;         std::vector<bool> mdownkeys;         std::vector<bool> mupkeys;         const int num_keycodes = 256; };  #endif // input_h 

i have no clue going on here. had similar problem yesterday, , couldn't figure out, tried saving project, closing code::blocks, restarting code::blocks, , reopening project. compiled , worked no apparent reason. no code changed or anything. tried reloading project here too, still gives same error.

you have method input in class code. mixing names of methods , types bad idea. consider code in 1 of class game methods:

input(); 

is method input call or trying create input class instance? try renaming input method.
