Radio

Define a struct called CRadio or RadioType. Specify attributes to indicate what station it is on, what band is selected (i.e. AM/FM), whether it is on or off, and the volume setting.

The following functions should be written to manipulate a radio.

void TurnOn( CRadio& Radio ); // sets On to true

void TurnOff( CRadio& Radio ); // sets On to false

void IncreaseVolume( CRadio& Radio ); // adds one to the current volume

void DecreaseVolume( CRadio& Radio ); // subtracts one from the current voulume

void SetStation(CRadio& Radio); // within this function you should ask the user for a new station

void SwitchBand( CRadio& Radio ); // if the current band is “AM” it is switch to “FM” and vice-versa

void Display ( const CRadio& Radio ); // neatly displays all of the info for a radio

Place the following restraints on each data member of the CRadio.

Station should be a float between 0-200.

Band should be a character string with 3 characters. It can have the values “AM” or “FM”.

On should be a bool. (true is on, false is off)

Volume should be an int between 0-50.

The following code should help you get started.

#include <iostream>

#include <string>

using namespace std;

struct CRadio

{

float Station;

string Band;

bool On;

int Volume;

CRadio();

};

CRadio::CRadio()

{

Station = 0;

Band = "FM";

On = false;

Volume = 0;

}

void main()

{

CRadio Radio;

//use all of the functions you have written to test your Radio.

}
