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 i;int c;
    for(i=0;i<19;i++){
        c=getchar();
        if(c==',')
            printf(" ");
        else
            printf("%c",c);
    }
    printf("\n");
    return 0;
}```

Assembly Code:

```assembly
	.file	"temp.c"
	.text
	.section	.text.startup,"ax",@progbits
