Grade averaging calculator

I am writing this program for a project and I can not get this to run at all. It executes the first cout command and then the command prompt disappears. If any of you can assist me it will be a big help. There seems to be no build errors by the way.

if statements() all of those grade = n; lines need to be return statements like the else is.

@line 49 - this can never happen, -1 is never returned from statements()

@line 57, this is exiting the program before GPA is calculated.

If you are using microsoft visual studio c++ then use system("pause") instead of return 0

and you also need to return grade in

int statements(char grade);

and why you are using -1
