int b(int a) { case(1):a+=1;return a; case(2):a+=2;return a; case(3):a+=3;return a; } 这段函数定义中当a=1时为社么只运行case(1)的语句,是不是当返回数据给函数时,就算函数调用完趁里?
百度知道不支持缩进，看代码累
switch(a%3)
{
``case 0: //当（a%3）==0时执行下面的语句直到遇到break或return
````m++;
````break;
``case 1: //当（a%3）==1时执行下面的语句直到遇到break或return
````m++;
``````switch(b%2) // 此switch在m++执行后继续执行
``````{
````````case 0: //当b%2==0时执行下面的语句直到遇到break或return
``````````m++;
``````````break;
````````default: //当b%2 !=0时执行下面的语句直到遇到break或return或后面没语句了自然结束此switch
``````````m++;
``````}
}
switch(a%3)
{
``case 0: //当（a%3）==0时执行下面的语句直到遇到break或return
````m++;
````break;
``case 1: //当（a%3）==1时执行下面的语句直到遇到break或return
````m++;
``````switch(b%2) // 此switch在m++执行后继续执行
``````{
````````case 0: //当b%2==0时执行下面的语句直到遇到break或return
``````````m++;
``````````break;
````````default: //当b%2 !=0时执行下面的语句直到遇到break或return或后面没语句了自然结束此switch
``````````m++;
``````}
}

不光是switch case。。。
遇到return 就是退出该函数了，如果是void的类型的函数，可以直接写"return;"本回答被提问者采纳

是的 不管什么时候 遇到return 就表示函数调用结束了
第4个回答 2011-06-30
是的，执行到return函数就退出了
