有没有复制C / C ++数组的功能？ [英] Is there a function to copy an array in C/C++?

问题描述

我是一个Java程序员学习C / C ++。所以我知道Java有像System.arraycopy）的函数（;复制的阵列。我在想，如果有C或C ++函数来复制一个数组。我只能够找到实现通过使用用于循环，指针等来复制的阵列。有没有我可以用它来复制一个数组的函数？

I am a Java programmer learning C/C++. So I know that Java has a function like System.arraycopy(); to copy an array. I was wondering if there is a function in C or C++ to copy an array. I was only able to find implementation to copy an array by using for loop, pointers,etc. Is there a function that I can use to copy an array?

推荐答案

由于C ++ 11，您可以直接与的std ::阵列复制数组：

Since C++11, you can copy arrays directly with std::array:

std::array<int,4> A = {10,20,30,40};
std::array<int,4> B = A; //copy array A into array B

下面是关于的std ::阵列
