input and output
In programming in c My question how to use an input in calculating another output? For an example Let say input1 = 55, input2 = 67, Then the average shows on the screen, Av1 + av2 = output 1. That sort of thing. A good example is when calculating an exam mark from 1 exam, a coursemark and assignment mark.

eof
what does eof mean and how is it use. How does c programming handle error handling.
