    cout<<"Prices of eggs";
    cin>>a;
    cout<<"Prices of bread";
    cin>>b;
    cout<<"Price of milk";
    cin>>c;
    cout<<"Prie of chicken";

    You can try putting in a cin.get(); or two at the end of your code, that's worked for me.

    Here is something simple you can do. Just add the header file conio.h and at the end of your source code, just before return 0; add the line getch(); this will wait until you press any key, then close your program.

    thanks

    getch(); worked fine, i remember that from C now,

    Whats the differnece between cin.get(); and getch(); ?

    They seems to be described as the same thing in the tutorials by cin.get(); doesnt seem to make any differnce ?

    thanks again

    conio.h isn't standard and isn't supported by all compilers.

    cin.get() uses buffered IO (like all standard language IO functions). You have to press <enter> to force data into your program.

    getch() from conio.h uses non-buffered IO, so a simple press of (almost) any key will be passed straight to your program.

    From the FAQ (already linked to), try these to see the difference.
    Code:
    #include <iostream> 
    
    int main(void)
    {
      std::cout <<"Press [Enter] to continue" <<std::endl;
      std::cin.get();
      return(0);
    }
    Code:
    #include <iostream> 
    #include <conio.h>
    
    int main(void)
    {
      std::cout <<"Press the anykey to continue" <<std::endl;
      getch();
      return(0);
    }
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
