Windows+R
cmd
Click OK
cd "your folder goes here" (Note the quotation marks.)
(then just type the name of your exe eg.) myprogram.exe
In your case:
Windows+R
cmd
Click OK
cd "C:\Quincy99\Programs\Chap02\"
pr02001.exe
OR just:
Windows+R
cmd
Click OK
"C:\Quincy99\Programs\Chap02\pr02001.exe"
The .exe isn't necessary, but I added it there to avoid confusion.

Because autoclose is a feature of Windows XP command shell. Put #include <conio.h> in your code and "::_getch();" in the very last line before return. (No quotation marks.)
| Code: | #include <iostream>
#include <conio.h>
int main()
{
// write to the screen
std::cout << "My first C++ program";
::_getch();
return 0;
} |
Note that ::_getch() isn't portable! I guess the best portable way would be doing std::cin.ignore(); and std::cin.sync();. I'm not sure tho.
Btw.. Thanks for the rep ;)

system("pause"); would be the better way. Since you are already using iostream, you don't need to include anything else. You also don't have to use goto. It also gives you a message "Press any key to continue".
| Code: |
#include <iostream>
int main()
{
system("pause");
}
|

Do cin.get(). Trust me, using labels is horrible, it shouldn't rly ever be used but there are certain times I guess you can use them. But just do this.
| Code: |
#include <iostream>
using namespace std;
int main()
{
cout<<"My first C++ program.\n";
cin.get();
}
|
Now it won't automaticly close and it will only close now if you click enter.

use cin.ignore() in situations where you prompt for info
