ue4 array copy c++

To copy an array in C++ using UE4 (Unreal Engine 4), you can follow these steps:

1. Declare the source array: Define the source array that you want to copy. For example, if you have an array named SourceArray, you can declare it like this:

TArray<int32> SourceArray;

1. Declare the destination array: Define the destination array where you want to copy the elements from the source array. For example, if you want to copy the elements to an array named DestinationArray, you can declare it like this:

TArray<int32> DestinationArray;

1. Resize the destination array: Resize the destination array to match the size of the source array. This is necessary to ensure that the destination array has enough space to hold all the elements. You can use the SetNum function to resize the array. For example:

DestinationArray.SetNum(SourceArray.Num());

1. Copy the elements: Use a loop to copy the elements from the source array to the destination array. You can use the Copy function to copy the elements. For example:

for (int32 Index = 0; Index < SourceArray.Num(); Index++)
{
    DestinationArray[Index] = SourceArray[Index];
}

1. Verify the copy: After the copy operation, you can verify that the elements have been successfully copied by printing both arrays. For example:

UE_LOG(LogTemp, Warning, TEXT("Source Array:"));
for (int32 Index = 0; Index < SourceArray.Num(); Index++)
{
    UE_LOG(LogTemp, Warning, TEXT("%d"), SourceArray[Index]);
}

UE_LOG(LogTemp, Warning, TEXT("Destination Array:"));
for (int32 Index = 0; Index < DestinationArray.Num(); Index++)
{
    UE_LOG(LogTemp, Warning, TEXT("%d"), DestinationArray[Index]);
}

By following these steps, you can copy an array in C++ using UE4.
