I got this assignment to write a program using the switch statement or the functional decomposition, that inputs a letter and outputs thr corresponding international Alpabet.

A Alpha
B Bravo
C Charlie

so on and so on

Is there anybody that can help me with this program?

C++ Syntax (Toggle Plain Text) 
  1. switch(value)
  2. {
  3.   case possibleValue1:
  4.     // do something
  5.     break;
  6.   case possibleValue2:
  7.     // do something
  8.     break;
  9.   /* ... */
  10.   default: // value wasn't any of possibleValue[1,n]
  11.     // do something
  12. }
Post some code, or some sort of attempt if you want more help

what do you mean by do something is that the alpabet word like Alpha
for the A character if it was entered?

use something like this:
C++ Syntax (Toggle Plain Text) 
  1. switch(tolower(letter))
  2. {
  3.   case 'a':
  4.     cout << "Alpha"; // or return, if this is just a function
  5.     break; // don't need this if you use return above
and repeat for all the letters.

That's icky, but it's a start.

How about you post an attempt, wheelz?

One quick solution would be to create a parallel array.

C++ Syntax (Toggle Plain Text) 
  1.  
  2. array one =
  3. [ "a",
  4.   "b",
  5.  
  6. ]
  7.  
  8. array two =
  9. [ "alpha",
  10.   "bravo",
  11. ]

Then you match each by their corresponding index offset.

Add this before switch
C++ Syntax (Toggle Plain Text) 
  1. char letter;
  2. cin>>letter;
The key to eliminating bugs from your code is learning from your mistakes.
