When allocating memory for a pointer int* myPointer, what is this statement doing?

myPointer = new int(8);

Versus this statement?

myPointer = new int[8];

I'm programming in C , and I know that using new will allocate memory on the heap, to which myPointer will point. But why does one statement use parenthesis instead of brackets? I know that brackets in myPointer = new int[8]; are used for an array, but what is the myPointer = new int(8); doing exactly?

CodePudding user response：

myPointer = new int[8]; allocates an array of 8 ints, and assigns the address of the beginning of the array to myPointer.

myPointer = new int(8); allocates one int, initializes it with the value 8, and assigns its address to myPointer.
