c++ initial value of dynamic array

Question

I need to dynamically create an array of integer. I\'ve found that when using a static array the syntax

int a [5]={0};

initializes correctl

Answer 1

To initialize with other values than 0,

for pointer array:

int size = 10;
int initVal = 47;
int *ptrArr = new int[size];
std::fill_n(ptrArr, size, initVal);
std::cout << *(ptrArr + 4) << std::endl;
std::cout << ptrArr[4] << std::endl;

For non pointer array

int size = 10;
int initVal = 47;
int arr[size];
std::fill_n(arr, size, initVal);

Works pretty Much for any DataType!

!Be careful, some compilers might not complain accessing a value out of the range of the array which might return a non-zero value
