CODE #include <iostream> using namespace std; int main() { system("cmd"); system("color 29"); switch("cmd"); { case 1 : system("color 01"); break; case 2 : system("color 02"); break; case 3 : system("color 03"); break; case 4 : system("color 04"); break; case 5 : system("color 05"); break; case 6 : system("color 06"); break; } cin.get(); } Errors: C:\Documents and Settings\1337\Desktop\Untitled1.cpp In function `int main()': 9 C:\Documents and Settings\1337\Desktop\Untitled1.cpp switch quantity not an integer 11 C:\Documents and Settings\1337\Desktop\Untitled1.cpp case label `1' not within a switch statement 12 C:\Documents and Settings\1337\Desktop\Untitled1.cpp break statement not within loop or switch 13 C:\Documents and Settings\1337\Desktop\Untitled1.cpp case label `2' not within a switch statement 14 C:\Documents and Settings\1337\Desktop\Untitled1.cpp break statement not within loop or switch 15 C:\Documents and Settings\1337\Desktop\Untitled1.cpp case label `3' not within a switch statement 16 C:\Documents and Settings\1337\Desktop\Untitled1.cpp break statement not within loop or switch 17 C:\Documents and Settings\1337\Desktop\Untitled1.cpp case label `4' not within a switch statement 18 C:\Documents and Settings\1337\Desktop\Untitled1.cpp break statement not within loop or switch 19 C:\Documents and Settings\1337\Desktop\Untitled1.cpp case label `5' not within a switch statement 20 C:\Documents and Settings\1337\Desktop\Untitled1.cpp break statement not within loop or switch 21 C:\Documents and Settings\1337\Desktop\Untitled1.cpp case label `6' not within a switch statement 22 C:\Documents and Settings\1337\Desktop\Untitled1.cpp break statement not within loop or switch I have a crap load of errors. The point of the program is to make the command prompt change colors. I have spare time right now if you can't tell.

I'm not sure if your problem has been solved now, but I just edited your code and added comments for you to see what happens where:

cpp

#include <iostream>

using namespace std;
int main()
{
      //system("cmd");
      // you dont need the line above, it doesn't do anything
      system("color 29"); // sets an initial colour state

      int choice; // the number that the user will enter

      cout << "Enter a number between 1 and 6: "; // prompt
      cin >> choice; // get the choice

      switch(choice) // switch to the corresponding case for choice
      {
                    case 1 : system("color 01");
                    break;
                    case 2 : system("color 02");
                    break;
                    case 3 : system("color 03");
                    break;
                    case 4 : system("color 04");
                    break;
                    case 5 : system("color 05");
                    break;
                    case 6 : system("color 06");
                    break;
                    // think about adding a default for errors
                    default: cout << "Invalid choice" << endl;
      }
      system("pause"); // Press any key to continue . . .
      return EXIT_SUCCESS; // everything went OK
}

Hope this helps

Code: CODE #include <iostream> using namespace std; // adder what the hell is wrong int main() { int number, color; int max; cout << "enter your number" << endl; cin >> number; cout << "enter your max number" << endl; cin >> max; for (number = 1; number <= max; number++) cout << number; for (color = 1; color <= max; color++) switch(color) { case 1 : system("color 01"); break; case 2 : system("color 02"); break; case 3 : system("color 03"); break; case 4 : system("color 04"); break; case 5 : system("color 05"); break; case 6 : system("color 06"); break; case 7 : system("color 07"); break; case 8 : system("color 10"); break; case 9 : system("color 12"); break; case 10 : system("color 13"); break; case 11 : system("color 14"); break; case 12 : system("color 15"); break; case 13 : system("color 16"); break; case 14 : system("color 17"); break; case 15 : system("color 20"); break; case 16 : system("color 21"); break; case 17 : system("color 22"); break; case 18 : system("color 23"); break; case 19 : system("color 24"); break; case 20 : system("color 25"); break; case 21 : system("color 26"); break; case 22 : system("color 27"); break; case 23 : system("color 30"); break; case 24 : system("color 31"); break; case 25 : system("color 32"); break; case 26 : system("color 33"); break; case 27 : system("color 34"); break; case 28 : system("color 35"); break; case 29 : system("color 36"); break; case 30 : system("color 37"); break; case 31 : system("color 40"); break; case 32 : system("color 41"); break; case 33 : system("color 42"); break; case 34 : system("color 43"); break; case 35 : system("color 44"); break; case 36 : system("color 45"); break; case 37 : system("color 46"); break; case 38 : system("color 47"); break; case 39 : system("color 50"); break; case 40 : system("color 51"); break; case 41 : system("color 52"); break; case 42 : system("color 53"); break; case 43 : system("color 54"); break; case 44 : system("color 55"); break; case 45 : system("color 56"); break; case 46 : system("color 57"); break; case 47 : system("color 60"); break; case 48 : system("color 61"); break; case 49 : system("color 62"); break; case 50 : system("color 63"); break; case 51 : system("color 64"); break; case 52 : system("color 65"); break; case 53 : system("color 66"); break; case 54 : system("color 67"); break; case 55 : system("color 70"); break; case 56 : system("color 71"); break; case 57 : system("color 72"); break; case 58 : system("color 73"); break; case 59 : system("color 74"); break; case 60 : system("color 75"); break; case 61 : system("color 76"); break; default : system("color 77"); color = 0; break; } cin.get(); }
