Question

Take the following program and translate it into PEP/9 assembly language:

#include <iostream>

using namespace std;

int fib(int n)

{

int temp;

if (n <= 0)

return 0;

else if (n <= 2)

return 1;

else {

temp = fib(n – 1);

return temp + fib(n-2);

}

}

int main()

{

int num;

cout << "Which fibonacci number? ";

cin >> num;

cout << fib(num) << endl;

return 0;

}

You must use equates to access the stack and follow the call to the function as discussed in the book (pass the parameter, return address, return a value and so on). There are NO global variables in the resulting code (except a global message of "Range num? "). It must be able to do sum a range greater than 2.

comments would be appreciated
