Reversing bits

[pattrick128]

Hi,

I'm trying to take in user input (which should be an integer), convert that to binary, flip the binaries and then print the decimal version of the flipped binaries.

When I test it with 4294967295 (which is the maximum number for 32-bit) it SHOULD return 0 once it's all flipped. I'm getting 2147483648 instead. Anything wrong with my program?

using namespace std;

int main() {
  int count;
  cin >> count; //expecting user input to be of type int
  int *array = new int[count];
  for (int i = 1; i <= count; i++) {
    cin >> array[i]; //user input at index 0, 1, 2, etc...
    bitset<32> myBits (array[i]); //the binary version of the decimal at index 0, 1, 2, etc...
    bitset<32> invertedBits = ~myBits; //flip all the bits
    cout << invertedBits.to_ulong() << endl; //print the decimal version of the bitsets
  }
}

2,147,483,647 is the maximum value for a 32-bit signed integer, which is the type you're storing the value in on line 8.
