PEP/9

Translate the following C++ program into assembly language:

 #include <iostream>

using namespace std;

int main() {

  char letter;

  int countA = 0,

       countB = 0,

       countC = 0;

  cin >> letter;

  do {

     switch (letter) {

        case 'A' : countA++; break;

        case 'B' : countB++; break;

        case 'C' : countC++; break;

      }

     cin >> letter;

  } while (letter != 'X');

  cout << "Number of A's " << countA << endl

         << "Number of B's " << countB << endl

         << "Number of C's " << countC << endl;

  return 0;

}

Use local variables (except for messages, of course) and the branch indexed for the switch statement.

The image contains a task to translate a C++ program into assembly language. Below is the C++ code provided: ```cpp #include <iostream> using namespace std; int main() { char letter; int countA = 0, countB = 0, countC = 0; cin >> letter; do { switch (letter) { case 'A' : countA++; break; case 'B' : countB++; break; case 'C' : countC++; break; } cin >> letter; } while (letter != 'X'); cout << "Number of A's " << countA << endl << "Number of B's " << countB << endl << "Number of C's " << countC << endl; return 0; } ``` ### Program Explanation: 1. **Header Inclusion and Namespace**: - The program includes the `<iostream>` header to facilitate input and output operations. - The `using namespace std;` directive is used to avoid needing to prefix standard library names with `std::`. 2. **Variables**: - `char letter;` is used to store user input. - Three integer variables, `countA`, `countB`, and `countC`, are initialized to zero to keep track of the number of times the letters 'A', 'B', and 'C' are entered. 3. **Loop and Switch Statement**: - A `do-while` loop reads characters from input until the character 'X' is entered. - The `switch` statement checks the input letter and increments the respective counter (`countA`, `countB`, or `countC`) based on whether the input is 'A', 'B', or 'C'. 4. **Output**: - After exiting the loop, the program outputs the number of times 'A', 'B', and 'C' have been entered. 5. **Return Statement**: - The program returns 0, indicating successful execution. ### Instructions: - Translate this C++ program into assembly language, focusing on using local variables and indexed branching for the switch statement logic.
