Question

Check if the given is right or wrong ( T or F)

1. Unlike the operators is most programming language, scheme operators do not have precedence associated with them.
2. Statically typed Functional languages often have “Option Types” can be used to substantially reduce the occurrences of Null Pointer Exceptions in production code.
3. The difference between statically Typed languages and dynamically Typed languages Is that statically Typed Languages always require explicit type declarations whereas Dynamically Typed languages do not.
4. A generic Type is a placeholder for a type which is not specifically known during program development but will be resolved at compile Time.
5. In object orient programming, the “constructor” is responsible for allocating memory to the object itself.

Answer 1

1.

• Unlike the operators is most programming language, scheme operators do not have precedence associated with them.
• Scheme operators are unspecified order.

Example:

(+5 8) = 13

Here operator + and operands are 5 and 8.

True

2.

• Statically typed Functional languages often have “Option Types” can be used to substantially reduce the occurrences of Null Pointer Exceptions in production code.
• Statically typed Functional languages include the below types
  • Inference
  • Immutability by default

True

3.

• The difference between statically Typed languages and dynamically Typed languages Is that statically Typed Languages always require explicit type declarations whereas Dynamically Typed languages do not.
• Statically Typed languages need an explicit type declaration by the developer.
• Dynamically Typed languages no need an explicit type declaration by the developer.

True

4.

• A generic Type is a placeholder for a type which is not specifically known during program development but will be resolved at compile Time.
• These are declared using the type variable and have any number of methods.
• These are specified by the users at the time of creation.

True

5.

• In object orient programming, the “constructor” is responsible for allocating memory to the object itself.
• Constructors are activated when an object is declared.
• Constructors uses for memory allocation and destructors are are used memory deallocation.

True
