18. Declaration Initializers

• Declaration initializer is an optional part of the variable declaration.

• Initializer provides initial value to our variables:

  
      int counter = 1000; 
      const double pi = 3.14; 
  
  

• Note: const transforms a variable into a constant value...

  • ...once initialized, const variable can never change again.

• Declaration initializer is the only way to set value of a const variable.
