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

```c
#include <stdio.h>
int main() {
    int i, cnt = 0;
    char c;
    for (i = 0; i < 4; i++) {
        if (scanf("%c", &c) == -1) return -1;
        if (c == '2') cnt++;
    }
    printf("%d\n", cnt);
    return 0;
}```
