switch case语句例子成绩

switch case语句可以用来根据不同的成绩输出不同的评级。下面是三个例子：

例子1：

#include<stdio.h>
int main() {
    int score;
    printf("请输入学生成绩: \n");
    scanf("%d",&score);
    switch(score/10) {
        case 10:
            printf("考了满分\n");
            break;
        case 9:
            printf("成绩优秀\n");
            break;
        case 8:
            printf("成绩良好\n");
            break;
        case 7:
            printf("成绩中等\n");
            break;
        case 6:
            printf("成绩及格\n");
            break;
        default:
            printf("成绩不及格\n");
            break;
    }
    return 0;
}

例子2：

#include<stdio.h>
int main() {
    long score;
    char mark;
    scanf("%ld", &score);
    switch (score/10) {
        case 10:
        case 9:
            mark='A';
            break;
        case 8:
            mark='B';
            break;
        case 7:
            mark='C';
            break;
        case 6:
            mark='D';
            break;
        default:
            mark='E';
            break;
    }
    printf("%c\n", mark);
    return 0;
}

例子3：

#include<stdio.h>
int main() {
    int score;
    printf("请输入学生成绩: \n");
    scanf("%d",&score);
    switch(score) {
        case 100:
            printf("满分\n");
            break;
        case 90:
            printf("优秀\n");
            break;
        case 80:
        case 70:
        case 60:
            printf("及格\n");
            break;
        default:
            printf("不及格\n");
            break;
    }
    return 0;
}

这些例子展示了使用switch case语句根据不同的成绩输出不同的评级。每个例子都包含了不同的判断条件和对应的输出语句。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
