having a problem

here is my code

Code:

 	cout<<"Number of Runners for Marathon in group";
	cin>>regs;

	while (runner > 0)
	{
		count++;

	if (runner >=1)
		fee= fee*count;
		
	if (runner >= 5)
		fee= fee*count;
		
	
	if (runner >=15)
		fee= fee*count;
		
	
	cout<<"Enter next group of runners";
	cin>>runner;
	}

	totalRunner= count;
	totalfee= chargeOne && chargeTwo && chargeThree;
	average= totalCharge/regs;

1. the program will allow as many groups to enter the runners that will participate
2.after the runners entered is 0.i want the program to display the amount of runners , total fee amount, and the average for each runner

here is the fee table

runner fee
1-5 runners= 20 each
5-15 runners= 50 each
15 runner or more= 70 each

Code:

int main()
{
	//v
	short runner = 0;
	short count = 0;
	double totalfee = 0.0;
	double average = 0.0;

	//i
	cout<<"Number of Runners for Marathon in group";
	cin>>runners;

	while (runner > 0)
	{
		count++;

	if (runner >=1)
		fee= fee*count;
		
	if (runner >= 5)
		fee= fee*count;
		
	
	if (runner >=15)
		fee= fee*count;
		
	
	cout<<"Enter next group of runners";
	cin>>runner;
	}

	totalRunner= count;
	totalfee= chargeOne && chargeTwo && chargeThree;
	average= totalCharge/runner;

	//o
	cout<<"Total Amount of Runners"<<count<<endl;
	cout<<"Total Amount"<<totalfee<<endl;
	cout<<"Average Per Runner"<<average<<endl;

	return 0;
}

here is the whole code
