Programming Language: C

Part 1: Do While and Switch Case

In the file onceplus.c, there is a function called process which takes one argument, a single integer, and returns an integer value.

There are also a number of symbolic constants defined at the beginning of the file.

The process function should include a switch case using the argument as its condition value.

For every symbolic constant at the beginning of the tile, there should be a separate case for that value. They should do the following:

For ERROR_404, the switch should print Not Found. on its own line.

For ERROR_403, the switch should print Forbidden. on its own line.

For ERROR_400, the switch should print Bad Request. on its own line.

# define ERROR_404 'a'

# define ERROR_403 'b'

# define ERROR_400 'c'

Also, include a case for EOF.

For EOF, the switch should print End of Stream and then return 0 or FALSE.

In the default case, print Valid input found: and then the argument as an ASCII character followed by a newline character.

If the argument wasnt EOF, then the process function should return 1 or TRUE.

In the main file, write a do while loop to read one character of input from standard input at a time and pass it to the process function as an integer. Since were letting the process function handle EOF, dont cast the input down to an integer just yet.

Use the process functions return value to decide if the loop should continue as the do whiles condition.

This program should only contain ONE (1) instance of the getchar function and NO OTHER INPUT FUNCTIONS!
