Mobile learning notes of u++ programming

Remove(value)： Delete all specified elements

TArray<int32> ValArr;
int32 Temp[] = { 10, 20, 30, 5, 10, 15, 20, 25, 30 };
ValArr.Append(Temp, ARRAY_COUNT(Temp));
// ValArr == [10,20,30,5,10,15,20,25,30]

ValArr.Remove(20);
// ValArr == [10,30,5,10,15,25,30]

RemoveSingle(value)： Delete the first... Found value Elements

ValArr.RemoveSingle(30);
// ValArr == [10,5,10,15,25,30]

RemoveAt(int)： Delete the subscript as int The elements of

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

RemoveAll(lambda)： for example ： Delete all 3 The value of a multiple of ：

ValArr.RemoveAll([](int32 Val) {
    return Val % 3 == 0;
});
// ValArr == [10,5,25]

 Empth()： Will delete all contents in the array

ValArr2.Empty();
// ValArr2 == []
