可以(在初始化后)在一行中(重新)设置数组的所有值吗? [英] Can one (re)set all the values of an array in one line (after it has been initialized)?

问题描述

在C语言中，我知道我可以创建一个像这样的数组

In C, I know I can make an array like this

int myarray[5] = {a,b,c,d,e};

但是，想象一下该数组已经被初始化了

However, imagine the array was already initialised like

int myarray[5];

然后在某个时候，我想不做任何设置/更改所有值

and then at some point afterwards, I wanted to set/change all the values without going

myarray[0] = a;
myarray[1] = b;
myarray[2] = c;
myarray[3] = d;
myarray[4] = e;

但是，更像是

myarray = {a,b,c,d,e};

之所以这样问，是因为如果我在堆上声明了数组，我将像这样初始化数组:

The reason why I ask this is because if I declare my array on the heap, I will initialise the array like:

int* myarray = malloc(5*sizeof(int));

然后，我希望能够在一行中输入所有值(主要是为了使代码看起来更简洁)

Then I would like to be able to enter in all the values in one line (mostly to make my code look cleaner)

推荐答案

memcpy(myarray, (int [5]){a,b,c,d,e}, 5*sizeof(int));
