Question

Translate the following C++ program into pep8 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;

}

Here is what I have so far:

BR main

letter: .equate 0 ;local varriable #2d

countA: .equate 2 ;local varriable #2d

countB: .equate 4 ;local varriable #2d

countC: .equate 6 ;local varriable #2d

stop

msgA: .ASCII "Number of A's "

msgB: .ASCII "Number of B's "

msgC: .ASCII "Number of C's "

.end
