C: Cannot initialize variable with an rvalue of type void*

Question

I have the following code:

int *numberArray = calloc(n, sizeof(int));

And I am unable to understand why I receive the following error.

Answer 1

You're using C memory re-allocation style in a C++ code. What you want to use is new in C++

So your code will become:

int n = 10; //n = size of your array
int *narray = new int[n];
for (int i = 0; i < n; i++)
    cout << narray[i];

Alternatively you can switch back to C and use calloc with casting.

int* numberArray = (int*)calloc(n, sizeof(int));
