C++

Must use the following functions

bool menuChoice( int& event )

: this function prints the menu and gets the users event

choice. It has one parameter, the users event choice, that is passed by reference so that the actual

parameter is changed by the function. It prints an error mssage if the users event choice is not in the

range [0, ..., 3] and returns false. Otherwise, it returns true.

int calcNumLaps( int event )

: this function calculates and returns the number of laps for an

event. If the event number is invalid, it returns 0 for the number of laps.

void calcAndPrintResults( int numLaps, const string& firstName, const

string&lastName )

: this function calculates and prints all lap accelerations by getting lap times

from the user. It has three parameters: 1) the number of laps, 2) the skaters first name, and 3) the

skaters last name. It also prints the End of analysis message for the particular skater.

You MUST use the following

main

function. Read through it carefully.

int main() {

string fName, lName; // first and last name of skater

int event; // 1 = 500m, 2 = 1000m, 3 = 1500m

int numLaps; // number of laps in event

bool valid; // user entered valid event number?

// set precision, etc.

cout.precision( 2 );

cout.setf( ios::showpoint | ios::fixed );

cout << "Welcome to the Short Track Speed Analyzer! ";

do { // while user didn't say quit

valid = menuChoice(event);

if ( valid && event != QUIT ) { // valid event

// get skater name

cout << "Skater first and last name: ";

cin >> fName >> lName;

// calc number of laps in event

numLaps = calcNumLaps( event );

// calculate and print acceleration for all laps

calcAndPrintResults( numLaps, fName, lName );

} // end if valid event

} while ( event != QUIT );

cout << "Thank you for using the Short Track Speed Skating

<< " Analyzer! ";

return 0;

}
