- Most functions in the C library return a value.…Even when that value isn't used it's available.…Returning a value allows functions to generate output.…Most of the time that output is based on the input…or arguments passed to the function.…In this movie I explain how functions return values.…They can simply generate the information…or they can manipulate arguments to produce specific output.…I'll also cover a few rules and regulations…regarding functions in the C language.…This code contains a function called gimmeAnA.…
It's a character function returning a char value.…The function has no input according…to its prototype at line three.…The function is called at line nine where its…return value is assigned to the the grade variable.…The function itself at line 15 merely…returns the single character A.…Build and run this code.…And I hope that that's true.…When a function returns a value…the value can be used immediately.…You can edit the source code for this exercise…so that the grade variable is removed.…
First delete the assignment and then replace the…
