Question

In assembler code must be a gcd.s file

So here is the C code I have written originally for the program. My question is how do I convert it to assembly code?

//C code

#include <stdio.h>

int fibonacci(int n) {
    if(n <= 2) {
        return 1;
    } else {
        return fibonacci(n-1) + fibonacci(n-2);
    }
}

int main(void) {
    int n;
    printf("Enter Fibonacci term: ");
    scanf("%d", &n);
    printf("The %dth Fibonacci number is %d\n", n, fibonacci(n));
    return 0;
}

Instructions

In C language. please display results

The Fibonacci Sequence is a series of integers. The first two numbers in the sequence are both 1; after that, each number is the sum of the preceding two numbers.

1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ...

For example, 1+1=2, 1+2=3, 2+3=5, 3+5=8, etc.

The nth Fibonacci number is the nth number in this sequence, so for example fibonacci(1)=1, fibonacci(2)=1, fibonacci(3)=2, fibonacci(4)=3, etc. Do not use zero-based counting; fibonacci(4)is 3, not 5.

Your assignment is to write an assembler code (Fibonacci.s) that asks the user for the nth term in the Fibonacci sequence. Your program should then calculate the nth Fibonacci number and print it out.

For example, you program should produce the following outputs:

Enter Fibonacci term: 6

The 6th Fibonacci number is 8
