in C++ write a program that is used to determine the average number of hot dogs eaten per contestant in a hot dog eating contest. You have to use the four functions defined below.

void welcomeMessage()

int getContestants()

int getDogsEaten(int)

doubleGetAverage(int, int)

here is my starter code:

 #include  #include  using namespace std; void welcomeMessage(); // prints welcome banner int getContestants(); // gets # contestants int getDogsEaten(int); // gets # eaten each and sums double getAverage(int, int); // calculates average # eaten int main() { welcomeMessage(); int nrContestants = getContestants(); // your code here return 0; } // welcomeMessage simply prints the welcome banner. // Parameters: none. // Input validation: none. // Returns: nothing. void welcomeMessage() { // your code here } // getContestants asks the user to input the number of contestants in // the hot dog eating contest. // Parameters: none. // Input validation: ensure at least 1 contestant is entered. // Returns: an integer, number of contestants int getContestants() { int input = 0; // your code here return input; } // getDogsEaten asks the user to enter the number of hot dogs eaten // for each contestant. It uses an accumulator variable to sum the // overall total eaten in the contest. // Parameters: an integer, number of contestants // Input validation: ensure that a positive integer (including 0) is entered // for the number of hot dogs eaten by a contestant // Returns: an integer, total number of hot dogs eaten in the contest. int getDogsEaten(int tempNrContestants) { int tempSum = 0, input = 0; // your code here return tempSum; } // getAverage simply calculates the average number of hot dogs eaten per // contestant in the hot dog eating contest. // Parameters: integer: total number of hot dogs eaten in the contest // integer: number of contestants // Input validation: none (no input happens in this function) // Returns: a double, average number of hot dogs eaten per contestant. double getAverage(int tempSum, int tempNrContestants) { double average = 0.0; // your code here return average; }
