Question

C++.

Write a program that asks the user to enter a single word and outputs the series of ICAO words that would be used to spell it out. The corresponding International Civil Aviation Organization alphabet or ICAO words are the words that pilots use when they need to spell something out over a noisy radio channel.

See sample screen output for an example:

Enter a word: program Phonetic version is: Papa Romeo Oscar Golf Romeo Alpha Mike

The specific requirement is that you write the program so that it determines the word corresponding to a specified letter using a Switch statement instead of an If structure.
As a point of reference, the ICAO alphabet is included below:

A Alpha N November B Bravo O Oscar C Charlie P Papa D Delta Q Quebec E Echo R Romeo F Foxtrot S Sierra G Golf T Tango H Hotel U Uniform I India V Victor J Juliet W Whiskey K Kilo X X-Ray L Lima Y Yankee M Mike Z Zulu

HINT: You may consider using character (char) array related processing or if you prefer to work with strings, determine the length of the variable string word and iterate through each letter in the string word using a for loop with a nested switch statement that has the necessary case labels matching the ICAO alphabets. Suggest converting all letters to uppercase to match the ICAO alphabet format.

Be sure to use proper formatting and appropriate comments in your code. Provide appropriate prompts to the user. The output should be clearly labeled and neatly formatted.

Code Explanation:

• Include the required libraries
• declare n and i as int and initialize i to 0
• Start the main function
• In the main function declare a char array word
• Input a word and assign to word
• find the length of word using strlen() which is present in string.h library
• Use while loop until i is not equal to n
• Then inside for loop use switch case with (char)toupper(word[i]). Here we converted each character in word to upper because if we input lower chars also it matches in case with upper chars. Otherwise we need to write two cases for lower and upper chars.
• print respective phonetic version using the cases.

Code:

#include <iostream>
#include<string.h>
using namespace std;

int main()
{
int n, i = 0;
char word[100];
cout << "Enter a word: ";
cin >> word;
n =strlen(word);
cout << "Phonetic version is: ";
while(i!=n)
{
switch((char)toupper(word[i]))
{

case 'A' : cout << "Alpha "; break;
case 'B' : cout << "Bravo "; break;
case 'C' : cout << "Charlie "; break;
case 'D' : cout << "Delta "; break;
case 'E' : cout << "Echo "; break;
case 'F' : cout << "Foxtrot "; break;
case 'G' : cout << "Golf "; break;
case 'H' : cout << "Hotel "; break;
case 'I' : cout << "India "; break;
case 'J' : cout << "Juliet "; break;
case 'K' : cout << "Kilo "; break;
case 'L' : cout << "Lima "; break;
case 'M' : cout << "Mike "; break;
case 'N' : cout << "November "; break;
case 'O' : cout << "Oscar "; break;
case 'P' : cout << "Papa "; break;
case 'Q' : cout << "Quebec "; break;
case 'R' : cout << "Romeo "; break;
case 'S' : cout << "Sierra "; break;
case 'T' : cout << "Tango "; break;
case 'U' : cout << "Uniform "; break;
case 'V' : cout << "Victor "; break;
case 'W' : cout << "Whiskey "; break;
case 'X' : cout << "X-Ray "; break;
case 'Y' : cout << "Yankee "; break;
case 'Z' : cout << "Zulu "; break;
default: cout << "default char";
}
i++;

}
cout << "\n";
return 0;
}
