C Question

Can one (re)set all the values of an array in one line (after it has been initialized)?

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

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

However, imagine the array was already initialised like

int myarray[5];

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;

but rather, something more like

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

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));

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

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