实验二

PART1 格式化输出函数printf（）和格式化输出函数scanf()

#include <stdio.h>
int main()
{
    int x=1234;
    float f=123.456;
    double m=123.456;
    char ch='a';
    char a[]="Hello,world";
    int y=3,z=4;
    printf("%d %d\n",y,z);
    printf("y=%d,z=%d\n",y,z);
    printf("%8d,%2d\n",x,x);
    printf("%f,%8f,%8.1f,%.2f,%.2e\n",f,f,f,f,f);
    printf("%lf\n",m);
    printf("%3c\n",ch);
    printf("%s\n%15s\n%10.5s\n%2.5s\n%.3s\n",a,a,a,a,a);
    return 0; 
} 

找出错误

#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;
}

PART4 switch语句体验练习

#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:)\n"); break;
        case 2: printf("low爆了:(\n"); break;
        default: printf("一言难尽，无法概括。。。\n");
    }
    return 

无break

有break

PART5 

#include<stdio.h>
int main()
{
    char ch;
    printf("请输入你的答案A,B,C,orD\n");
    scanf("%c",&ch);
    if(ch=='A')
    printf("binggo,you are right");
    else
      printf("try again~");
    return 0;
 }

实验总结与体会：大致熟练了循环语句用法，实验内容虽然有点多，但是收获不少。
