How To Open a text file

Hi Every One!
I am trying to open a text file from OpenGL but does not open. Kindly help me in this problem. The following are the codes which I am using for opening a text file from OpenGL.

case ‘o’:

FILE* file = fopen(“E:\Files\aa.txt”, “r+”)



OpenGL has absolutely nothing to do with file IO.

Your question makes no sense. What are you actually trying to do?

I am trying to open a text file or other exe file from OpenGL code and the file opening should be opened by pressing “case button” in OpenGL which I have send the code in the above example.
