    Unhappy Need serious help w/ program! Please help!

    I need help w/ this program. I don't know what to do.

    I need a function to present a menu, send the menu choice to main.

    Menu items are:
    - 1 Add
    - 2 Subtract
    - 3 Multiply
    - 4 Divide

    Main prints out number of choice, bad choice.
    Use Switch.
    Cannot use If statements.

    Here's something:
    ------------------------------------------------------------------------------------
    #include<iostream.h>
    #include<iomanip.h>

    int main()

    {

    int one_digit_menu_choice;
    int first_digit;
    int second_digit;
    int sum;
    int difference;
    int product;
    int quotient;

    cout<<"\n Enter 1 add, 2 subtract, 3 multiply, 4 divide";

    cin>>one_digit_menu_choice;

    while (one_digit_menu_choice!=0)

    {switch (one_digit_menu_choice)

    {
    case 1:
    cout<<"You have chosen choice:"<<one_digit_menu_choice;
    break;
    case 2:
    cout<<"You have chosen choice:"<<one_digit_menu_choice;
    break;
    case 3:
    cout<<"You have chosen choice:"<<one_digit_menu_choice;
    break;
    case 4:
    cout<<"You have chosen choice:"<<one_digit_menu_choice;
    break;
    default:
    cout<<"You have chosen an incorrect choice";
    break;

    }

    cout<<"Please enter first digit.\n";
    cin>>first_digit;

    cout<<"Please enter second digit.\n";
    cin>>second_digit;
    ------------------------------------------------------------------------------------
    This is all I have right now. I'm still working on it. Any help would greatly be appreciated! Thanks!

    lol for one thing you should add
    Code:
    return 0;
    }
    at the end and maybe it will work . But if that's not the problem I'm working on it right now it'll give me something to do and maybe I'll learn a thing or two from it.
    Hey, you gotta start somewhere

    Red face here it is

    that wasn't really too hard... I guess I'm getting better (don't even say anything). Here's the code it works fine and it got a face lift to (that is if a console program CAN get a face lift)

    Code:
    #include<iostream.h> 
    #include<iomanip.h> 
    
    int main() 
    
    { 
    
    int choice;
    float dig1;
    float dig2;
    double answer;
    cout<<"1. Add\n2. Subtract\n3. Multiply\n4. Divide\n\nChoice: "; 
    
    cin>>choice;
    
    switch (choice)
    {
    	case 1: 
    	cout<<"\nYou have chosen to add"; 
    	break; 
    	case 2: 
    	cout<<"\nYou have chosen to subtract"; 
    	break; 
    	case 3: 
    	cout<<"\nYou have chosen choice to multiply"; 
    	break; 
    	case 4: 
    	cout<<"\nYou have chosen choice divide"; 
    	break; 
    	default: 
    	cout<<"\nYou have chosen an incorrect choice"; 
    	break;
    }
    
    cout<<"\n\nPlease enter first digit: "; 
    cin>>dig1;
    
    cout<<"Please enter second digit: "; 
    cin>>dig2;
    
    if(choice==1)
    {
    	answer=dig1+dig2;
    }
    if(choice==2)
    {
    	answer=dig1-dig2;
    }
    if(choice==3)
    {
    	answer=dig1*dig2;
    }
    if(choice==4)
    {
    	answer=dig1/dig2;
    }
    
    cout<<"\nThe answer is "<<answer;
    
    return 0;
    }
    Spiffy...

    forever loop one_digit_menu_choice is never changed within the loop
    while (one_digit_menu_choice!=0)

    {switch (one_digit_menu_choice)

    {
    case 1:
    cout<<"You have chosen choice:"<<one_digit_menu_choice;
    break;
    case 2:
    cout<<"You have chosen choice:"<<one_digit_menu_choice;
    break;
    case 3:
    cout<<"You have chosen choice:"<<one_digit_menu_choice;
    break;
    case 4:
    cout<<"You have chosen choice:"<<one_digit_menu_choice;
    break;
    default:
    cout<<"You have chosen an incorrect choice";
    break;

    }
