c++ - How to resolve this compilation error -

I'm trying to compile some OpenGL code because I get this error

1 & gt; C: \ users \ student \ documents \ visual studio 2012 \ projects \ openglproject1 \ openglproject1 \ initshader.h (10): error C4996: 'fopen': This function or variable may be unsafe. Consider using fopen_s instead to disable the exclusion, see _CRT_SECURE_NO_WARNINGS Use Online Help for information. Include Program

 Can you tell me how do I modify the program?   
 
 
 You can define a header file that generates an error, before adding the header file Or "project-> property- & gt;" The project can be applied to the entire project by adding settings. Configuration Properties- & gt; C / C ++ - & gt; Preprocessor- & gt; Preprocessor Definitions  
  #define _CRT_SECURE_NO_WARNINGS #include "initshader.h" // ... here your code   
 if you are using pre-compiled headers And if the header that generates the errors is included in  stdafx.h , then add it to the  stdafx.h  header or in your project settings as described above.
