part1：格式化输出函数printf（）和格式化输入函数scanf（），
%d：按十进制整数输出；%f:按浮点数输出；%c：按字符输出；%e：按指数形式输出；%s:按字符串输出
修饰符%lf：在d,o,x,u前，指定输出精度long型
#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, %0.2f, %.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; }
#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 0; }
去掉break后
没有去掉break之前
#include<stdio.h> int main() { int x; printf("请输入你的答案(A,B,C or D):"); scanf("%c",&x); if(x=‘A‘) printf("Binggo,you are right"); else printf("try again"); return 0; }
