Programming & Computer Science Answers

Create your own Python code examples that demonstrate each of the following. Do not copy examples from the book or any other source. Try to be creative with your examples to demonstrate that you invented them yourself.

• Example 1: Define a function that takes an argument. Call the function. Identify what code is the argument and what code is the parameter.
• Example 2: Call your function from Example 1 three times with different kinds of arguments: a value, a variable, and an expression. Identify which kind of argument is which. 
• Example 3: Create a function with a local variable. Show what happens when you try to use that variable outside the function. Explain the results.
• Example 4: Create a function that takes an argument. Give the function parameter a unique name. Show what happens when you try to use that parameter name outside the function. Explain the results.

The input will be a single line containing two integers and operator(+, -, *, /, and %) similar to 3 + 5.

output

If the given operator is "+", print the sum of two numbers.

If the given operator is "-", print the result of the subtraction of the two numbers.

If the given operator is "*", print the multiplication of the two numbers.

If the given operator is "/", print the result of the division of the two numbers.

If the given operator is "%", print the result of the modulus operation of the two numbers.

Compile time polymorphism using operator overloading

Create a class Distance with feet and inches. Write an overloaded function to copy the value of one distance object into another distance object using = operator overloading.

which is the correct syntax for returning an object by pointer?

a) void functionName ( ){ }

b) object functionName( ) { }

c) class object functionName( ) { }

d) ClassName functionName ( ){ }

How may byte are used in the following main

knowing that int use 4 byte

answer number only, like: 4

class point

{

int x, y;

int main()

{

point obj;

point arr[2];

}

class employee

{

private : int id; char

name [20];

public :

employee(int x=100)

{

id=x;

}

};

Select one:

one parameter

b. Objects can be created with zero or

one parameter

c. Objects can be created with many

parameters

d. Objects can only be created with

zero parameter

Create a function with a local variable. Show what happens when you try to use that variable outside the function. Explain the results.

Define a function that takes an argument. Call the function. Identify what code is the argument and what code is the parameter.
