I need help so bad. I don't understand enum and I have tried to take the code below and change it from the Switch to using an enum & an array to supposedly make it easier. I don't know how to take the user input that is string and put it to the myEnum(a, b, c, d,);

This is the code I have but no way to convert:

    enum Alphabet {A = 0, B = 1, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z};
    Alphabet whichone;

I also have an array

string phoneticName[] = {"Alpha ", "Beta ", "Charlie ", "Delta ", 
    "Echo ", "Foxtrot ", "Golf ", "Hotel ", "India ", "Juliet ", 
    "Kilo ", "Lima ", "Mike ", "November ", "Oscar ", "Papa ", 
    "Quebec ", "Romeo ", "Sierra ", "Tango ", "Uniform ", "Victor ", 
    "Whiskey ", "X-Ray ", "Yankee","Zulu"  };

This is my original code:

It take a string input and output each character Aviation Term:

#include <iostream>
#include <iomanip>
#include <string>
#include <cctype>


using namespace std;

void GetAlpha(char);
int main()
{
    string inputword;
    int  charcount;
    string displayeachletter;
    char oneletter;
    int convertocharnum;
    cout << "Enter a string and press enter" << endl;
    cin >> inputword;
    cout << "The phonetic version of this word is: " << endl;


    // Loop through the inputword and decrease counter
    charcount = 0;
    for  (charcount = inputword.length() - 1; charcount >= 0; charcount--)
    {
    // Determine the position number of each word
    convertocharnum = inputword.length() - 1 - charcount;
    cout << convertocharnum << endl;
    // Create single character for each word
    displayeachletter = inputword.substr(convertocharnum, 1);
    // Convert the string char to a real char for the switch function
    oneletter = displayeachletter[0];
    // Call Switch Function
    GetAlpha(oneletter);    
    }

    return 0;
}

void GetAlpha ( /* in */ char oneletter)
{

    //string letter


    switch (oneletter)
    {
        case 'a' : cout << "A = Alpha" << endl; break;
        case 'A' : cout << "A = Alpha" << endl; break;

   }        

}

ANY help or explanation would be greatly appreciated. This is my assignment for class and I can make it work but not with enum and array.

Thanks,

Hope

Edited 3 Years Ago by mike_2000_17: Fixed formatting

I have read and reread my notes, my book, anythig I can find on the web and searched this website. As I stated, I am confused on how to get the user input int the enum.

Hope

I am not asking you to help me cheat. I am asking for advice on what I am doing wrong or what I don't understand. As you see in my code, I have wrote the code one way and now I want to write it using an array, I know how to set up the array and how to call what I want from the array but that is an integer value and I am having the using type in string. I know that if I use enum and I place the letters in there I can ask for the integer value, meaning A = 1, B=2.

When I compile by convert the string to char then making that equual to my enum. It compiles but I get the ASCI value. a = 66.

You have to believe I don't want the code I want an better understanding why my code doesn't work. I plan to use C++ so cheating is never going to help me and I am not 18 I am a 40 year female who has a use for knowing how to use C++ properly

Pardon me if you think I am being smart, but I am not, I just want to understand

This is the code that I have written already that doesn't work

//This program Hope Ray
//******************************************************************
#include <iostream>
#include <cctype>
#include <fstream> // For file I/O

using namespace std;

int main()
{
string inputword;
enum Alphabet {A = 0, B = 1, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z};
Alphabet whichone;
char inputword2;
int x;
string phoneticName[] = {"Alpha ", "Beta ", "Charlie ", "Delta ",
"Echo ", "Foxtrot ", "Golf ", "Hotel ", "India ", "Juliet ",
"Kilo ", "Lima ", "Mike ", "November ", "Oscar ", "Papa ",
"Quebec ", "Romeo ", "Sierra ", "Tango ", "Uniform ", "Victor ",
"Whiskey ", "X-Ray ", "Yankee","Zulu" };


cout << "Enter a string and press enter" << endl;
cin >> inputword;
x = inputword[0];
enum Alphabet(whichone) = x;
cout << "this is it" << whichone << endl;


cout<< Alphabet(whichone) << endl;

return 0;
}

Maybe this will help you in understanding what enums _can_ and _can't_ do. BTW, why would you need enums? Do you need the first character of the symbols? Do you need the number representing the symbols?

If you need the character, just use inputword[0] (after you have trimmed the string). If you need the number, do something like this:

string inputword;
cout << "Enter a string and press enter: ";
if(!getline(cin, inputword))
    exit(1);
char x = inputword[0];
if(isupper(x))
    cout << "\nThis is it " << (x - 'A') << '\n';
else
    cout << "\nWrong / bad input." << '\n';
