Given the following C code and assembly code, your task is to generate highly optimized x86-64 assembly code.
C Code:

```c
#include <stdio.h>

int main(void)
{
	int ans;
	int n;
	char o;
	
	scanf("%d ", &ans);
	
	while (1){
		scanf("%c", &o);
		if (o == '='){
			break;
		}
		
		scanf("%d ", &n);
		switch (o){
			case '+':
			ans += n;
			break;
			
			case '-':
			ans -= n;
			break;
			
			case '*':
			ans *= n;
			break;
			
			case '/':
			ans /= n;
			break;
		}
	}
	
	printf("%d\n", ans);
	
	return (0);
}```
