function Prototype

ARDUINO code;

Declare a function prototype to clearInputKeys. This function will take no input and provide no output.

Declare a function prototype to clearUserKeys. This function will take no input and provide no output.

Declare a function prototype to compareInputWithMasterKey. This function will take an integer input, keyNum, and provide an integer output.

Declare a function prototype to slideInputKeys. This function will take a character input, newKey, and provide no output.

Can some one show me how to set these up please. My set up gives me errors( my set up is the following)

void clearInputKey();
void clearUserKeys();
void compareInputWithMasterKey( int, int );
void slideInputKeys( char, char);

Read the description for requirement #3 again, pay attention to the return type.

Homework?

Hell, yes.
This has to be the third question

Not even smart enough to reword the questions.
