Question 1

Type Casting:

1. What is type casting?
2. Why is type casting important?
3. How to type cast?

Answer 1

1. ~changing the type of a variable’s value temporarily to perform an operation
   ~the variable is unchanged after the operation and type casting
2. ~you don’t need a separate variable to hold the same value but in a different type
   •ex: variable_as_int=1 and variable_as_float=1.0
   ~you can specify a data type that you need at the time of the operation, this gives you flexibility
3. ~(new_type) expression
   •ex: (float) some_integer
