Question 7

---

7. Which of the following statements is/are True ?
P : C programming language has a weak type system with static types.
Q : Java programming language has a strong type system with static types.

Code :

1. (1) P only
2. (2) Q only
3. (3) Both P and Q
4. (4) Neither P nor Q

Answer : (3) Both P and Q

• Static Typing
  Essentially, static typing means that variable types are checked at “compile-time”, or before the code is executed.
• Statement P is True.
  C programming language has a weak type system with static types because it lets you define object types as structures, but it doesn’t do much to enforce or remember them. C automatically convert between many types. C++ and Objective-C go further with the definitions but still don’t enforce the resulting types.
• Statement Q is True.
  Java programming language has a strong type system with static types because Java forces you to define all types and checks them with a virtual machine.

Example of weak static languages: Weak Static Languages: C, C++ And Objective-C

Find here an example to understand strong static language: Strong Static Languages: Java

Both P and Q statements are true.

So, Option (1) is correct answer.

Reference : Understanding Types; Static vs Dynamic, & Strong vs Weak.
