C# Programming Functions and Procedures

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.

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.

int

boolean

float

string

Sometimes

No

Maybe

Yes

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.

myFunction();

callFunction(myFunction);

executeFunction(myFunction);

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'

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.

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.
