小弟初学刚刚学到IF-ELSE嵌套，变了个程序，但DEV在getch();上边的ELSE处打错，小弟不解请达人指导。感谢
#include<iostream>
#include<conio.h>
using namespace std;
int main(){
int number=0;
cout<<"Enter a number between 1 to 100";
cin>>number;
if(number<100 && number>1)
cout<<"You entered "<<number;
if(number<50) cout<<"The number is less than 50";
else if(number=50) cout<<"The number is 50";
else cout<<"The number is bigger than 50";
else
cout<<"What you entered is illegle";
getch();
return 0;
}
下边的1楼 有欠缺，小于50没问题 大于50时 不对 输出还是50

cin>>number;
if(number<100 && number>1)
{
cout<<"You entered "<<number<<endl;
if(number<50) cout<<"The number is less than 50"<<endl;
else if(number=50) cout<<"The number is 50"<<endl;//这句错了：应该是 //number==50
else cout<<"The number is bigger than 50<<endl";
}
else
cout<<"What you entered is illegle<<endl";
getch();
return 0;
}//
if else 语句都是在满足条件时执行后面的一条语句（或一个语句块（block）） 所以对 每个 IF ELSE IF ELSE 都推荐 配成对大括号
{}
