c - switch 语句，跳出 for 循环以重新开始 switch

Question

我在主 while 循环内有一个开关，它将运行我的游戏。我正在尝试打破我的开关，以便转到不同的案例。下面的例子更好地解释了这一点:

int j = 0;
While(1){
switch(j){
case 0:  ....
        break;
case 1: 
      for( i =0; i > 100; i++){
       if(lives == 0)
        j = 2;
        break; //this is where I want to break out of my switch to go to case 2. But it         
               //breaks out of my for loop. I do not know how to get around this. Thank 
               //you!
       }
 case 2: //some stuff I want to do
}

}

Answer 1

我猜你只想打case 2当lives == 0 。如果是这样，您需要输入 break;在{ }与 j = 2; 一起- 这只会在 lives == 0 时打破循环。那么如果你放置 break;在 case 0 末尾您将终止开关，然后重新输入开关，因为 while(1)然后你点击case 2: .

你的 for 循环应该正确地是 for(i = 0; i < 100; i++)不是for(i = 0; i > 100; i++)

int j = 0;
While(1){
  switch(j){
  case 0:  ....
    break;
  case 1: 
    for( i =0; i < 100; i++){
      if(lives == 0) {
        j = 2;
        break;
      }
    }
    break;
 case 2: //some stuff I want to do
  }
}
