Question
I need help with my C++ code everything runs fine and you are able to enter the data, but I cannot figure out why it will not display the data for formula answers like BA, SA, OBA, and SBP. Also i could use help with the formatting to make the chart look neater. Here is my code Thanks.
#include <iostream>
#include <iomanip>
using namespace std;
const int MAXLASTNAME = 20;
const int MAXFIRSTNAME = 10;
const int MAXPLAYERS = 20;
struct Baseball {
char FirstName[MAXFIRSTNAME+1];
char LastName[MAXLASTNAME+1];
float AB;
float singles;
float doubles;
float triples;
float HR;
float walks;
float HBP;
float StolenBases;
float CaughtStealing;
};
void checkPlayers(int &players);
int getData(Baseball[]);
void showData(Baseball[], int);
int main()
{
Baseball stats[MAXPLAYERS];
int players = getData(stats);
showData(stats, players);
}
int getData(Baseball stats[])
{
int i, players;
cout << "How many players would you like to enter data for(1-20): ";
cin >> players;
cout << endl;
checkPlayers(players);
for(i=0;i<players;i++) {
cout << "Please enter player #" << i+1 << "'s first name: ";
cin >> stats[i].FirstName;

Explanation / Answer
hi every thing is file but you have to declare calcBA, calcSA, calcOBA, calcSBP in global
The below code is working properly..
Program
#include <iostream>
#include <iomanip>
using namespace std;
const int MAXLASTNAME = 20;
const int MAXFIRSTNAME = 10;
const int MAXPLAYERS = 20;
struct Baseball {
char FirstName[MAXFIRSTNAME+1];
char LastName[MAXLASTNAME+1];
float AB;
float singles;
float doubles;
float triples;
float HR;
float walks;
float HBP;
float StolenBases;
float CaughtStealing;
};
//you have declare in global
double calcBA, calcSA, calcOBA, calcSBP;
void checkPlayers(int &players);
int getData(Baseball[]);
void showData(Baseball[], int);
int main()
{
Baseball stats[MAXPLAYERS];
int players = getData(stats);
showData(stats, players);
return 0;
}
int getData(Baseball stats[])
{
int i, players;
cout << "How many players would you like to enter data for(1-20): ";
cin >> players;
cout << endl;
checkPlayers(players);
for(i=0;i<players;i++) {
cout << "Please enter player #" << i+1 << "'s first name: ";
cin >> stats[i].FirstName;
cout << "Please enter player #" << i+1 << "'s last name: ";
cin >> stats[i].LastName;
cout << "Please enter the number of at bats for player #" << i+1 << ": ";
cin >> stats[i].AB;
cout << "Please enter the number of singles for player #" << i+1 << ": ";
cin >> stats[i].singles;
cout << "Please enter the number of doubles for player #" << i+1 << ": ";
