Simpler way to set multiple array slots to one value

Question

I\'m coding in C++, and I have the following code:

int array[30];
array[9] = 1;
array[5] = 1;
array[14] = 1;

array[8] = 2;
array[15] = 2;
array[23] = 2;
array[1         


        

Answer 1

This function will help make it less painful.

void initialize(int * arr, std::initializer_list list, int value) {
    for (auto i : list) {
        arr[i] = value;
    }
}

Call it like this.

initialize(array,{9,5,14},2);
