例3-1 猜数
猜数
程序核心——判断语句if-else以及其镶嵌
程序
#include<stdio.h>
int main()
{
int mynumber=38,younumber;//计算机指定猜的数,输入的猜的数
printf("Input you number:");
scanf("%d",&younumber);
if(mynumber==younumber)//两数相等
printf("OK!your are right!");
else
if(younumber>mynumber)//输入数大
printf("sorry!you number is bigger than my number!");
else//输入数小
printf("Sorry!you number is smaller than my number!");
return 0;
}
结果
Input you number:43
sorry!you number is bigger than my number!

分析
重点:判断语句之间的镶嵌,注意判断条件是否存在遗漏
