Functions and Arrays

[pausmile]

I am supposed to modify my current program to such that the user has the choice of entering either 5 males, 5 females, or quitting (the while loop should be retained to repeat the menu until the user chooses to quit. The program also needs to have a function that prints a header (return type of void). It also needs a function that calculates the average height of all 5. I have no idea where to start other than the function is double average (int ht0, int ht1, int ht2, int ht3, int ht4);

This is the code I already have

#include <iostream>
using namespace std;


int main()
{
	char sex;
	double height;
	int weight;
	int name;
	
	bool b=true;
  
	do
	{	
		cout << "Please choose from the following..\n\nA = Data for Female\nB = Data for Male\n\nC = choose to quit" << endl;

		cin >> sex;
		sex = toupper(sex);

		if (sex =='C')
		{
			cout << "Good-bye!" << endl;
			b=false;
			system("pause");
		}

		if (sex == 'A')
		{	
			cout << "Enter Name" << endl;
			cin >> name;
			cout << "Enter height in inches" << endl;
			cin >> height;
			cout << "Enter weight in pounds" << endl;
			cin >> weight;
			if ((height >= 58) || (height <= 64))
			{	if (weight <= 114)
			{	cout << "Weight is low!" << endl;	}				
			else if ((weight >= 115) || (weight <= 133))
			{	cout << "Weight is on target" << endl;	}
			else
			{	cout << "Weight is high!" << endl;	}
			}

			else if ((height >= 65) || (height >= 71))
			{
				if (weight <= 117)
				{ 
					cout << "Weight is low!" << endl;
				}
				else if ((weight >= 136) && (weight <= 156))
				{ 
					cout << "Weight is on target!" << endl;
				}
				else
				{
					cout << "Weight is high!" << endl; 
				}
			}
		}
		else if (sex == 'B')
		{
			cout << "Enter height in inches" << endl;
			cin >> height;
			cout << "Enter weight in pounds" << endl;
			cin >> weight;
			if ((height >= 61) || (height <= 67))
			{
				if (weight <= 114)
				{
					cout << "Weight is low!" << endl;
				}
				else if ((weight >= 123) || (weight <= 133))
				{ 
					cout << "Weight is on target!" << endl;
				}
				else
				{ 
					cout << "Weight is high!" << endl; 
				}
			}
			else if ((height >= 68) && (height <= 75))
			{
				if (weight <= 155)
				{
					cout << "Weight is low!" << endl; 
				}
				else if ((weight >= 156) || (weight <= 175))
				{ 
					cout << "Weight is on target!" << endl; 
				}
				else
				{
					cout << "Weight is high!" << endl;
				}
			}
		}

	} while(b==true);
}

You basically need to just loop through an array, increase the average weight each time, and then divide by the total number of people at the end. I didn't test this yet, but it should work.

#include <iostream>

using namespace std;

struct Person
{
	char sex[7];
	float height;
	int weight;
	char* name;
};

int main()
{
	float averageheight = 0.0f;
	int averageweight = 0;
	Person* people = new Person[5];
	for(int i = 0; i < sizeof(people); i++)
	{
		cout << "Please choose Male, Female or Quit." << endl;
		cin >> people[i].sex;
		
		for(int j = 0; j < sizeof(people[i].sex); j++)
		{
			people[i].sex[j] = (char)toupper((int)people[i].sex[j]);
		}
		
		if(people[i].sex == "QUIT")
		{
			cout << "Good-bye!" << endl;
			break;
		}
		else if(people[i].sex == "MALE")
		{
			cout << "What is his name?" << endl;
			cin >> people[i].name;
			cout << "What is his height in inches?" << endl;
			cin >> people[i].height;
			cout << "What is his weight in pounds?" << endl;
			cin >> people[i].weight;
			
			if((people[i].height >= 58) || (people[i].height <= 64))
			{
				if(people[i].weight <= 114)
					cout << "Weight is low!" << endl;
				else if((people[i].weight >= 115) || (people[i].weight <= 133))
					cout << "Weight is on target!" << endl;
				else
					cout << "Weight is high!" << endl;
			}
			else if((people[i].height >= 65) || (people[i].height >= 71))
			{
				if(people[i].weight <= 117)
					cout << "Weight is low!" << endl;
				else if((people[i].weight >= 136) && (people[i].weight <= 156))
					cout << "Weight is on target!" << endl;
				else
					cout << "Weight is high!" << endl;
			}
		}
		else if (people[i].sex == "FEMALE")
		{
			cout << "What is her name?" << endl;
			cin >> people[i].name;
			cout << "What is her height in inches?" << endl;
			cin >> people[i].height;
			cout << "What is her weight in pounds?" << endl;
			cin >> people[i].weight;
			
			if((people[i].height >= 61) || (people[i].height <= 67))
			{
				if(people[i].weight <= 114)
					cout << "Weight is low!" << endl;
				else if((people[i].weight >= 123) || (people[i].weight <= 133))
					cout << "Weight is on target!" << endl;
				else
					cout << "Weight is high!" << endl;
			}
			else if((people[i].height >= 68) || (people[i].height >= 75))
			{
				if(people[i].weight <= 155)
					cout << "Weight is low!" << endl;
				else if((people[i].weight >= 156) && (people[i].weight <= 175))
					cout << "Weight is on target!" << endl;
				else
					cout << "Weight is high!" << endl;
			}
		}

		averageheight += people[i].height;
		averageweight += people[i].weight;

		if(i == sizeof(people) - 1)
		{
			averageheight /= sizeof(people);
			averageweight /= sizeof(people);
			cout << "The average weight is " << averageweight << ", and the average height is " << averageheight << ".";
		}
	}
	system("pause");
	return 0;
}

I didn't test this yet,

Obviously. If you use his code I would suggest allocating some memory for the name variable of each Person to point to before trying to store stuff where it points. Better yet, use a std::string.

I have no idea where to start other than the function is double average (int ht0, int ht1, int ht2, int ht3, int ht4);

Since you're going to be dealing with arrays:

double average( int values[], int n_values); might be more appropriate.
