C语言统计成绩问题，预期输出该怎么写

#include<stdio.h>
int main(){
    int n,i,l1=0,l2=0,l3=0,a;
    printf("Input n:");
    scanf("%d",&n);
    for(i=1;i<=n;i++){
        printf("Input score for student no.%d :",i);
        scanf("%d",&a);
        if(a>=85&&a<=100) l1++;
        else if(a>=60&&a<=84) l2++;
        else if(a>=0&&a<60) l3++;
    }
    printf("85~100: %d\n",l1);
    printf("60~84: %d\n",l2);
    printf("0~60: %d",l3);
    return 0;
}

觉得有用的话采纳一下哈
