application wont launch on fresh Xp

[jonezy]

Right so i tryed to dable in c++ a while back but lost my footing at the start and am now trying to regain some skill....

so yes..i started right at the begining..on a fresh install of Xp with SP2.. but ive compiled my program and it just flashes up on screen and disappears when i try to run it....

 
#include <iostream>

int main()
{
    std::cout << "oldest code ever...!\n";
    return 0;
}

any ideas?

After the std::cout line insert std::cin.get().

yes i see...otherwise the program has nothing to stay open for... cheers

another one for you...

this is the code i get from a tutorial website:

 #include <iostream.h>
 int main()
 {
      int x = 5;
      int y = 7;
      cout "\n";
      cout << x + y << " " << x * y;
      cout "\n";
      return 0;
 }

this hasnt a hope of workign on my pc... im not sure if this is because of the compiler or not...
but if i put this :

#include <iostream>
int main()
{
    int x = 5;
    int y = 7;
    std::cout "\n";
    std::cout << x + y << " " << x * y;
    std::cout "\n";
    return 0;
}

it nearly works...apart from compiler says it expects ; before string constant..... i dont no where to go now.....

Nah, just an old website teaching old C++, where your compiler accepts new C++.

One of the major differences in source code is the use of namespaces, such as the std:: you have in front of your cout calls.

> std::cout "\n";
Try std::cout << "\n";

[manutd]

Also try

cout << endl << x + y << " " << x * y << endl;

Then remove the cout << "\n".

[jonezy]

yep that works now.. so its going to be an effort in itself learning from this site.... hmm...might look around for somewhere else...

cheers,

Pick up a good book.

One of the problems with online tutorials is the fact some of them are pre-standard. ie: teaching older syntax than more compliant compilers would cough errors up at. The tutorial on this site is a good one and uses modern syntax so perhaps try there. Or do as manutd suggested about the book. Oh, and stay away from herb stuilt books ( spelling ?) he is awful.

>>schildt?

Yeah thas the guy. I used to own one of his books. Waste of money reading about buggy code and poor practices.
