True

False

Answer 1

When a cast operator is applied to a variable, it changes the contents of a variable.
Answer: False

A cast operator used in typecasting, is a unary operator, when used and applied to a variable, is just a way and it converts one data type to another, not the contents or value of a variable. 'Cast' means 'Type'.

Example: In case, a long value is required to be stored, processed, manipulated in computations, and represented, you could typecast the long int to a simple integer (int). Similarly, one can convert from enums to ints, or ints to floats. Explicitly using a cast operator, you could convert values from one numeric type to another. Cast operator, especially is, used for numeric values. Also, typecasting is used to make one data type of variable, like an int, act like another, like a string or char, for an operation. It thus is and used to assign a value of one type to a variable of another type.

The cast does not affect the original value of a variable in any way. Casting is only an operator.
