要从数组中的特定索引中删除一个元素: ["bar", "baz", "foo", "qux"] list.splice(2, 1)// Starting at index position 2, remove one element["bar", "baz", "qux"] list.splice(2,2)// Starting at index position 2, remove two elements["bar", "baz"] 该拼接()调用将返回任何删除元素...
ValArr.RemoveAt(2);// Removes the element at index 2 // ValArr == [10,5,15,25,30] ValArr.RemoveAt(99);// This will cause a runtime error as // there is no element at index 99 我们可以使用RemoveAll来删除与匹配条件匹配的元素。例如:删除所有3的倍数的值: ValArr.RemoveAll([](int...
若element未找到,则使用end记录如果将element插入mArray时的位置。 可以发现,indexOf函数有两个作用: 查找element在mArray中的位置 若element在mArray中不存在,则返回将element插入mArray中的位置的取反。 resize ArraySet中没有resize函数,这里的resize表示ArraySet在add和remove时可能会执行的扩容操作,这里的扩容可能...
