它可以无条件地跳转到指定的标签。
它可以用于从深层嵌套的循环或切换案例标签转移控制。
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!
