    I have a compiling error...

    Well, I started with switches, and completely understand them and how they work. But, I have 2 errors when trying to compile my improved number game. Here is the code:

    Code:
    #include <stdio.h>
    #include <iostream.h>
    #include <conio.h>
    
    int main()
    {
            //loop count
            int loopCount;
            cout<<"Enter number of guesses you wish to make:\n";
            cin>> loopCount;
    
            //entering guesses
            while(loopCount>0)
            {
                    loopCount=loopCount--;
                    int guess;
                    cout<<"Enter a guess:\n";
                    cin>> guess;
    
                    if(guess==88)
                    {
                    cout<<"That is correct! Press any key to exit.\n";
                    getch();
                    break;
                    }
    
                    else
                    switch(guess)
                    {
                            if(guess>88)
                            {
                                    //lower
                                    cout<<"That is incorrect. The number is lower. Only "<<loopCount<<" guesses remaining.\n";
                                    break;
      else
                                    //higher
                                    cout<<"That is incorrect. The number is higher. Only "<<loopCount<<" guesses remaining.\n";
                                    break;
                            }
                            break;
                    }
            }
            return 0;
    }
    The errors I get are:

    number.cpp(37)Error: parse error before 'else'
    number.cpp(32)Error: Warning: unreachable code at beginning of switch statement

    I have no idea how to fix either of those. I've been toying around with them for quite a while, but I'm clueless.

    while(loopCount>0)
    {
    loopCount=loopCount--;
    int guess;
    cout<<"Enter a guess:\n";
    cin>> guess;

    if(guess==88)
    {
    cout<<"That is correct! Press any key to exit.\n";
    getch();
    break;
    }

    else
    {
    if(guess>88)
    cout<<"That is incorrect. The number is lower. Only "<<loopCount<<" guesses remaining.\n";
    else
    cout<<"That is incorrect. The number is higher. Only "<<loopCount<<" guesses remaining.\n";
    }
    }
    return 0;
    }

    It seems like you are forgetting braces.

    For your if statements you have braces, but not for else's.
    Try including them

    switch is only used with case statements ex.

    switch(menuchoice)
    {
    case 1:
    //do something
    break;
    case 2:
    //do something else
    break;
    case default:
    //usually an error message or something
    }

    I am extremely dumb......-_-

    Thanks for the help. I forgot about the braces around the else statements.

    Yeah, you helped. In C++ for dummies, it doesn't say you need braces before and after the 'else'. It doesn't even show that in example programs.

    Cool

    Now you realize the extent that dummy books have.
