[Help]2nd small c++ project

ok so this is the code i learned form a vc++ book ;

Code:

#include "stdafx.h" #include <iostream> using namespace std; using namespace System; int main() { int length; length = 7; cout << "The length is "; cout << length; return 0; }

my problem is , it executes just fine but everytime i open it , it closes after like 1 second . does anyone know how to fix that ?

Put system("PAUSE"); before you return..
You can also put
char Whit;
cin >> Whit; before you return

You can either do what whit said, or if your compiler supports it like Visual C++ Express Edition 2008 look for a button that says Start without Debugging

Use the search button. Asked many times.

im not sure if the earlier versions do this, but if its visual studio 2010 professonal (express does it too) then when u make the project, make sure its a win32 application and just make the new project with the default options (dont touch anything). The main function will be _tmain(blah blah blah){ but it works exactly the same. Also call me stupid but whats the using namespace system; for? ive never seen it

extremely inefficient.

use 2008, it auto pauses before return

cin.get();

before you return execution.

add

Code:

int f;
cin >> f;
return 0;

or just cin.get();

Has already been said.

cin.ignore()

It will ignore 1 key pres, also Drake, instead of using cout<<. Use printf():

int length = 7
printf("The lenght is: %d\n", length); // the printf function will replace the %d with the first decimal argument following

I suppose next you'll be telling him to use malloc instead of new. Tsk tsk.

Still printf()'s better

right above return 0 put

cin.get();
