Why we use const array in a function, even the original array are not const?

I hope that these code express my question more clearly.

double xxxx(const double* const array){
//...
}
int main(){
double* array = new double [5];
xxxx(array);
}

Is it actually create a new const array in the stack and heap by the input of the function?

You use it to indicate that you're not going to modify the array. This way, the function can be used with both const and non-const original arrays. – Barmar Feb 15 '18 at 01:59
It doesn't create a new array. – Barmar Feb 15 '18 at 01:59
