C# Programming Functions and Procedures

What is the difference between a function and a procedure in C#?

• A function returns a value while a procedure does not.

• A function can only be used in object-oriented programming while a procedure can be used in any programming paradigm.

• A function can have multiple return statements while a procedure can only have one return statement.

• A function and a procedure are the same thing.

How do you define a procedure in C#?

• Use the 'bool' keyword followed by the procedure name and parentheses.

• Use the 'void' keyword followed by the procedure name and parentheses.

• Use the 'string' keyword followed by the procedure name and parentheses.

• Use the 'int' keyword followed by the procedure name and parentheses.

What is the return type of a function in C#?

• int

• boolean

• float

• string

Can a procedure have a return type in C#?

• Sometimes

• No

• Maybe

• Yes

What is the purpose of using parameters in functions and procedures?

• Parameters are used to restrict the input values in functions and procedures.

• Parameters are used to make the code block more complex and difficult to understand.

• Parameters are used to pass values out of the code block in functions and procedures.

• The purpose of using parameters in functions and procedures is to pass values into the code block for more flexibility and reusability.

How do you call a function in C#?

• myFunction();

• callFunction(myFunction);

• executeFunction(myFunction);

How do you call a procedure in C#?

• By using the keyword 'run'

• By using the name of the procedure followed by parentheses

• By using the keyword 'invoke'

• By using the keyword 'execute'

What is the difference between value parameters and reference parameters in C#?

• Value parameters pass the actual parameter by value, while reference parameters pass the actual parameter by reference.

• Value parameters and reference parameters are the same in C#.

• Value parameters pass a copy of the actual parameter, while reference parameters pass the memory address of the actual parameter.

• Value parameters pass the memory address of the actual parameter, while reference parameters pass a copy of the actual parameter.

How do you pass parameters by reference in C#?

• Use the 'byref' keyword before the parameter type in the method signature.

• Use the 'in' keyword before the parameter type in the method signature.

• Use the 'out' keyword before the parameter type in the method signature.

• Use the 'ref' keyword before the parameter type in the method signature.
