command prompt always closes in a milisecond...o.o

[s0opatro0pa]

hmm...well the title says it all...im REEEEEEEEEEEAAAAAAAALLLYY noob so it could easily be a stupid mistake [most probably is]
im using Dev-C++ and after i press F9, it pops up command prompt for a milisecond and BOOM gone... Dev doesnt tell me what im doing wrong too

all help is appreciated! =D

The problem is that after your program runs and finishes the window closes.

There are two solutions; the bad one is to add a delay to the end of your program (usually by reading some input). The other option is to open a comand promt and run your program from the command line.

o thanks!
but in school, i tried this on c-free and it always gave a "press any button to continue..." at the end of the program. is there anyway that i can do that too?

Add this to the end of main():

[syntax="c++"]
string a;
cout << "Press enter to continue:";
cin >> a;
[/syntax]

I haven't tried it and I am fairly new to c++, so there may be a better way.

That would work, assuming you are using namespace std; Generally speaking it's a poor idea to do that though, so it would be std::string, std::cout and std::cin.

Thanks, that's good to know. Another reason to love c++

umm..lol..not to sound rude, but i REEEEEEEEEEEEAAAAAAAAAAAAAAALLLLLLLLLLLLLYYY meant that i am REEEEEEAALLY newbie, like one or 2 days that i started this so im still on hello world for the most part. i tried hello world with iostream but it says that it doesnt exist =s
i stoped the thing from closing with the #include conio.h and getch ();

oh so yeaa, can anyone tell me why the iostream doesnt exist??

[md]

Can you post your code? Just include it in [ code][/code] tags.

[s0opatro0pa]

well this is the new one im working on that says iostream wasnt found and string wasnt found either...

code:

#include <iostream> #include <string> #include <conio.h> using namespace std; int main() {     string Name, Age;         cout << "            Welcome\n\n";     cout << "Please enter your name and age...\n";     Cout << "Age:";     cin >> Age ;     Cout "\nName:"     cin >> Name;         Cout << " Your name is " << Name << ", and you are " << Age <<", years old."     getch (); }

o i found out that mistake with the inability to find the iostream.........
i saved it as c instead of c++, heh
guess i was more nooby than i thought =p

C, C++... it's all text.

your eyes cant distinguish what happens in a single milliseconds. its more like 50-100 milliseconds.

informative. but in order for ur os to render the command prompt window, do computations and make it disappear again for your eye to notice, it requires more than one millisecond. not to mention all the context switching between threads (ie os, virus scan, etc)

[s0opatro0pa]

lol the milisecond thing was a exaggeration, lol but still some nice information
