### break 语句的作用: ###

跳出当前循环,中断当前循环

#include <iostream>
    using namespace std;
    int main()
    {
         for (int i = 0; i < 10; i++)
         {
              cout << i << endl;
              if (i==5)
              {
                   break;
              }
              
         }
         return 0;
    }

###  continue语句的作用: ###

跳过本次循环, 整体循环继续.

#include <iostream>
    using namespace std;
    int main()
    {
         for (int i = 0; i < 10; i++)
         {
              if (i==5)
              {
                   continue;
              }
               cout << i << endl;
              
         }
         return 0;
    }

打印结果:

###  goto语句的作用: ###

改变语句执行的顺序,结束循环.

#include <iostream>
    using namespace std;
    int main()
    {
         for (int i = 0; i < 10; i++)
         {
              cout << i << endl;
              goto label;
         }
    
    label:
         cout << "11111" << endl;
         return 0;
