Which of the following are True about User defined function?They are defined using define keywordIt is a must to have a return keyword in every functionFunction can have only maximum of 20 statementsThey provide code-reusability

The statements about User defined functions are evaluated as follows:

1. They are defined using define keyword: False. In most programming languages like Python, Java, C++, user-defined functions are defined using the 'def' or 'function' keyword, not 'define'.

2. It is a must to have a return keyword in every function: False. It is not necessary for every function to have a return keyword. A function can simply perform an action without returning any value.

3. Function can have only maximum of 20 statements: False. There is no such limit on the number of statements a function can have. It can have as many as required for the logic of the function.

4. They provide code-reusability: True. One of the main advantages of user-defined functions is that they provide code reusability. Once a function is defined, it can be used multiple times throughout the program.

The statements about User defined functions are evaluated as follows:

1. They are defined using define keyword: This statement is False. In most programming languages like Python, Java, C++, user-defined functions are defined using the 'def' or 'function' keyword, not 'define'.

2. It is a must to have a return keyword in every function: This statement is False. It's not necessary for every function to have a return keyword. Some functions perform an action without returning a value.

3. Function can have only maximum of 20 statements: This statement is False. There's no such limit on the number of statements a function can have. It depends on the logic and requirement of the function.

4. They provide code-reusability: This statement is True. One of the main advantages of user-defined functions is that they provide code reusability. Once a function is defined, it can be used over and over again in your program, which saves time and makes the code more readable.

The statements about User defined functions are evaluated as follows:

1. They are defined using define keyword: This statement is False. In most programming languages like Python, Java, C++, user-defined functions are defined using the 'def' or 'function' keyword, not 'define'.

2. It is a must to have a return keyword in every function: This statement is False. It's not necessary for every function to have a return keyword. A function without a return statement will return a default value. For example, in Python, it will return None.

3. Function can have only maximum of 20 statements: This statement is False. There is no such limit on the number of statements a function can have. It depends on the logic that you want to implement.

4. They provide code-reusability: This statement is True. One of the main advantages of user-defined functions is that they promote code reusability. Once a function is defined, it can be used over and over again in your program, which saves you from writing the same code multiple times.
