C++ goto语句用法

C ++ goto语句也称为跳转语句。它用于将控制权转移到程序的其他部分。它无条件跳转到指定的标签。

它可用于从深层嵌套的循环或开关案例标签转移控制权。

C ++ Goto语句示例

让我们看一下C ++中goto语句的简单示例。

#include <iostream>
using namespace std;
int main()
{
ineligible:  
         cout<<"You are not eligible to vote!\n";  
      cout<<"Enter your age:\n";  
      int age;
      cin>>age;
      if (age < 18){  
              goto ineligible;  
      }  
      else  
      {  
              cout<<"You are eligible to vote!";   
      }       
}

输出：

You are not eligible to vote!
Enter your age:
16
You are not eligible to vote!
Enter your age:
7
You are not eligible to vote!
Enter your age:
22
You are eligible to vote!
