Question

Keep as simple as possible

1. How does a function differ from a module?

2. What is the purpose of the RETURN statement in a function?

3. Discuss the relationship between parameterList and argumentList

4. IF the first parameter has the Integer data type and the 2nd parameter has the Double data type, what data types should the first and second arguments have?

Answer 1

1. In simplest manner we can define a function as a statement or group of statements bounded with a specific name which having a specific task and will result some value is known as a function. A function is a type module which will return some value after it is being called.

But a module can be defined as a group of functions stored in a file. In simplest form we can define a module as a group os statements that exist within a program which is used for a specific task.

2. The purpose of a return statement in a function is to terminate the execution of a function and send the control to the calling part. In other words for some function we can say that the return statement will return the final value of the function which intern called as the result.
3. In a function the parameterList and argumentList are closely associated with each other. The aregumentList are the values that are provided in a function call whereas the parameterList are the name of variables that is used in function declaration or definition to stores the argumentList.
4. IF the first parameter has the Integer data type and the 2nd parameter has the Double data type, then the first argument must be Integer type and second must be Double type.
