实验二

#include <stdio.h>
int main() {
    double x,y;
    char c1,c2,c3;
    int a1,a2,a3;
    scanf("%d%d%d",a1,a2,a3);
    printf("%d,%d,%d\n",a1,a2,a3);
    scanf("%c%c%c",&c1,&c2,&c3);
    printf("%c%c%c\n",c1,c2,c3);
    scanf("%lf,%lf",&x,&y);
    printf("%lf,%lf\n",x,y);
    return 0;
}

#include <stdio.h>
int main() {
    int level;
    printf("输入现在状态等级(1-5):  ");
    scanf("%d",&level);
    switch(level) {
        case 1: printf("high翻了:)"); break;
        case 2: printf("low爆了:("); break;
        default: printf("一言难尽，无法概括。。。");
    }
    return 0;
}

#include<stdio.h>
int main(){
    int option;
    printf("请输入你的答案(A，B，C or D):   ");
    scanf("%c",&option);
    switch(option){
        case 'A': printf("Binggo, you are right~");break;
        default: printf("try again~");break;    
}   
return 0;        
}
