Why does DOS always close after the program completes?
I've never acctuelly had this problem before, so I was wondering why the following program always closes right after you reach the end of the program (outputing the stored data).
Here is the code so far:
Code:
#include <iostream.h>
#include <stdio.h>
#include <string.h>
//class
class NameDataSet
{
public:
char firstName[128];
char lastName[128];
int ssNumber;
};
//getdata function will retrieve info from user in consol
int getData(NameDataSet& nds)
{
std::cout<<"\nEnter your first name:\n";
std::cin>>nds.firstName;
if
((strcmp(nds.firstName, "exit") == 0)
||
(strcmp(nds.firstName, "EXIT") == 0))
{
return 0;
}
std::cout<<"\nEnter your last name:\n";
std::cin>>nds.lastName;
std::cout<<"\nEnter credit card number:\n";
std::cin>>nds.ssNumber;
return 1;
}
//display data will display all data in the database
void displayData(NameDataSet& nds)
{
std::cout<<"Your name(s):\n" << nds.firstName << " " << nds.lastName << "\n";
std::cout<<"Your creditcard number(s):\n" << nds.ssNumber << "\n";
}
int main(int nArg, char* pszArgs[])
{
NameDataSet nds[25];
std::cout<<"Read name/credit card information\n" << "Enter 'exit' for first name to exit\n";
int index=0;
while (getData(nds[index]))
{
index++;
}
std::cout<<"\nEntries\n";
for (int i = 0; i < index; i++)
{
displayData(nds[i]);
}
return 0;
}
The book I'm reading right now that I got it from, mentioned it in the first chapter, but since I never experieinced this happening in the first chapter, but never gave a way to solve it. Also, I had never had this problem up until now. Can anybody explain how to stop this from happening?
