Correct way to cast address of int to char pointer

If I need to read int from ifstream

int myInt = 0;
fileStream.read(reinterpret_cast<char*>(&myInt), sizeof(int));

is using reinterpret_cast<char*> correct way to accomplish that?

Yes. Prefer c++ style casts, instead of c style casts.

As suggested in comments, a better way to use the read method function is : 

int myInt = 0;
fileStream.read(reinterpret_cast<char*>(&myInt), sizeof(myInt));
