值追加到c数组 [英] Appending values to c array

问题描述

这是一个很简单的问题，但我不知道如何做到这一点。

This is a very simple question, but I don't know how to do this.

例如，我有一个名为阵列阵列包含值 [1,2,3,4,5,6] ，我想添加第七值， 7 ，到阵列使其包含 [1,2,3,4， 5,6,7] 。

For example, I have an array called Arraycontaining the values[1,2,3,4,5,6], and I want to add a seventh value, 7, to the array so it contains[1,2,3,4,5,6,7].

有一个函数来做到这一点？我是否需要任何多余的头文件？任何帮助将是AP preciated。

Is there a function to do that? Do I need to include any extra header files? Any help would be appreciated.

推荐答案

如果它被宣布为这样一个普通数组：

If it is a plain array declared as such:

int Array[] = {1,2,3,4,5,6};

那么你就不能多值添加到它。如果有提前提供了一些空间，然后您可以添加更多的值：

Then you wouldn't be able to add more values to it. If there's some space provided in advance then you may add more values:

int Array[7] = {1,2,3,4,5,6};
Array[6] = 7;

如果您使用C ++，我会建议使用的std ::矢量，但它不存在C。

If you used c++, I would recommend using std::vector, but it does not exist in C.
