I can't fathom this. It should probably be a dynamic array.

[DittenhauserJA]

The following program needs a user set number of players. I then must calculate their batting average. The output will include playername, jersey number, average, and it must print on a clean screen for each player. I am not allowed to use global variables. I just don't know what to do or how to use dynamic arrays. They confuse me.



#include <iomanip>
#include <iostream>
#include <math.h>
using namespace std;
//Prototypes

void menu();
void cls();
void getinput();
void calculation(double bats[players], double hits[players], char playername[players] [30], double jersey[players]);
void output(double bats[players], double hits[players], char playername [players] [30], double average [players], double jersey[players]);


//main
int main()
{
cout << "Welcome to The Batting Program." << '\n';
cout << "Please choose from below: " << '\n';
menu();
}

void menu()
{
int choice;
cout << "1. Enter the information" << '\n';
cout << "2. Exit Batting Program" << '\n';
cout << "Enter the choice you would like below: ";
cin >> choice;

switch (choice)
{
case 1:
getinput();
break;

case 2:
return;
break;

default:
cout << '\n' << "Please choose from the available" << '\n';
menu();
break;
}

}
void getinput()
{
int players;
cout << "How many Players are on the Team? ";
cin >> players;

int counter;
char playername[players] [30];
double jersey[players];
double bats[players];
double hits[players];


for (counter = 0; counter < (players); counter ++)
{
cout << "What is the name of the player?";
cin>> playername [counter];
cin.ignore(1000, '\n');
cout << "What is that players jersey number";
cin >> jersey [counter];
cout << '\n';
cout << "How many times have you been at bat? ";
cin >> bats [counter];
cout << '\n';
cout << "How many times have you hit the ball?";
cin >> hits[counter];
}
calculation(bats, hits, playername, jersey);
}
void calculation(double bats[players], double hits[players], char playername[players] [30], double jersey[players])
{
int counter;
double average[players];
for (counter = 0; counter < (players); counter ++)
{
((average [counter]) = ((hits[counter])/(bats[counter])));
}
cls();
output(bats, hits, playername, jersey, average);
}
void cls()
{
system("cls");
}
void output(double bats[players], double hits[players], char playername [players] [30], double average [players], double jersey[players], int players)
{
int counter;
char junk [30];

cout << "Here is the information about the players: ";
for (counter = 0; counter < (players); counter ++)
{
cout << "Name: " << playername[counter];
cout << "Jersey Number: " << jersey[counter];
cout << "Batting Average: " << average[counter];
cout << "Press any key to continue ";
cin >> junk;
cls();
}
menu();
}

Use code tags. You're giving a hard time to read all that.
