8. Boolean to integer conversion

• Boolean types can be converted to plain integer numbers and back:

  
  int main() 
  {
      int i = -1; 
      bool b = i; // b will be true
      int x = b;  // x will be set to 1
      x = 0;
      b = x;      // b will be set to false
      return 0;
  } 
  
  

• Note: no assumptions should be made regarding the size of bool type. On many systems it takes 8 bits to store a boolean variable.
