5. Variables can be initialised by a calculation involving other variables

A variable can be initialised by a calculation involving other variables:

using namespace std;
#include 

int main ()
{
  double a = 12 * 3.25;
  double b = a + 1.112;

  cout << "a contains: " << a << endl;
  cout << "b contains: " << b << endl;

  a = a * 2 + b;

  double c = a + b * a;

  cout << "c contains: " << c << endl;

  return 0;
}

Output

a contains: 39 b contains: 40.112 c contains: 4855.82
