===== FINDING THE DIVISIBILITY OF A NUMBER =====

Take a simple arithmetic problem: what’s left over when you divide an odd number by an even number? The answer may not be easy to compute, but we know that it will most likely result in an answer which has a decimal remainder. How would we determine the divisibility of a number in a programming language like Java? That’s where the modulus operator comes in handy.

To have divisibility means that when you divide the first number by another number, the quotient (answer) is a whole number (i.e – no decimal values). Unlike the division operator, the modulus operator (‘%’), has the ability to give us the remainder of a given mathematical operation that results from performing integer division.

To illustrate this, here is a simple program which prompts the user to enter a number. Once the user enters a number, they are asked to enter in a divisor for the previous number. Using modulus, the program will determine if the second number is divisible by the first number. If the modulus result returns 0, the two numbers are divisible. If the modulus result does not return 0, the two numbers are not divisible. The program will keep re-prompting the user to enter in a correct choice until a correct result is obtained.


The above program determines if number ‘A’ is divisible be number ‘B’ via modulus. Unlike the division operator, which does not return the remainder of a number, the modulus operator does, thus we are able to find divisibility between two numbers.

To demonstrate the above code, here is a sample run:

Welcome to My Programming Notes' Java Program.

Please enter a value: 21
Please enter a factor of 21: 5

Incorrect, 21 is not divisible by 5.

Please enter a new multiple integer for 21: 7
Correct! 21 is divisible by 7

(21/7) = 3

===== CELSIUS TO FAHRENHEIT CONVERSION DISPLAYING DEGREES DIVISIBLE BY 10 =====

Now that we understand how modulus works, the second program shouldn’t be too difficult. This function first prompts the user to enter in an initial (low) value. After the program obtains the low value from the user, the program will ask for another (high) value. After it obtains the needed information, it displays all the degrees, from the range of the low number to the high number, which are divisible by 10. So if the user enters a low value of 3 and a high value of 303, the program will display all of the Celsius to Fahrenheit degrees within that range which are divisible by 10.

Java || Random Number Guessing Game Using Random & Do/While Loop

This is a simple guessing game, which demonstrates the use of the “Random” class to generate random numbers. This program first prompts the user to enter a number between 1 and 1000. Using if/else statements, the program will check to see if the user obtained number is higher/lower than the pre defined random number which is generated by the program. If the user makes a wrong guess, the program will re prompt the user to enter in a new number, where they will have a chance to enter in a new guess. Once the user finally guesses the correct answer, using a do/while loop, the program will ask if they want to play again. If the user selects yes, the game will start over, and a new random number will be generated. If the user selects no, the game will end.

Java || Compute The Sum From A String Of Integers & Display Each Number Individually

Here is a simple program, which was presented in a Java course. This program was used to introduce the input/output mechanisms which are available in Java. This assignment was modeled after Exercise 2.30, taken from the textbook “Java How to Program” (early objects) (9th Edition) (Deitel). It is the same exercise in both the 8th and 9th editions.

Our class was asked to make a program which prompts the user to enter a non-negative integer into the system. The program was supposed to then extract the digits from the inputted number, displaying them each individually, separated by a white space (” “). After the digits are displayed, the program was then supposed to display the sum of those digits to the screen. So for example, if the user inputted the number “39465,” the program would output the numbers 3 9 4 6 5 individually, and then the sum of 27.

C++ || Modulus – Celsius To Fahrenheit Conversion Displaying Degrees Divisible By 10 Using Modulus

This page will consist of two simple programs which demonstrate the use of the modulus operator (%).

REQUIRED KNOWLEDGE FOR THIS PROGRAM

Modulus
Do/While Loop
Functions
Simple Math - Divisibility
Celsius to Fahrenheit Conversion

===== FINDING THE DIVISIBILITY OF A NUMBER =====

Take a simple arithmetic problem: what’s left over when you divide an odd number by an even number? The answer may not be easy to compute, but we know that it will most likely result in an answer which has a decimal remainder. How would we determine the divisibility of a number in a programming language like C++? That’s where the modulus operator comes in handy.

To have divisibility means that when you divide the first number by another number, the quotient (answer) is a whole number (i.e – no decimal values). Unlike the division operator, the modulus operator (‘%’), has the ability to give us the remainder of a given mathematical operation that results from performing integer division.

To illustrate this, here is a simple program which prompts the user to enter a number. Once the user enters a number, they are asked to enter in a divisor for the previous number. Using modulus, the program will determine if the second number is divisible by the first number. If the modulus result returns 0, the two numbers are divisible. If the modulus result does not return 0, the two numbers are not divisible. The program will keep re-prompting the user to enter in a correct choice until a correct result is obtained.

The above program determines if number ‘A’ is divisible be number ‘B’ via modulus. Unlike the division operator, which does not return the remainder of a number, the modulus operator does, thus we are able to find divisibility between two numbers.

To demonstrate the above code, here is a sample run:

Please enter a value: 21
Please enter a factor of 21: 5

Incorrect, 21 is not divisible by 5.
Please enter a new multiple integer for that value: 7

Correct! 21 is divisible by 7
(21/7) = 3

===== CELSIUS TO FAHRENHEIT CONVERSION =====

Now that we understand how modulus works, the second program shouldn’t be too difficult. This function first prompts the user to enter in an initial (low) value. After the program obtains the low value from the user, the program will ask for another (high) value. After it obtains the needed information, it displays all the degrees, from the range of the low number to the high number, which are divisible by 10. So if the user enters a low value of 3 and a high value of 303, the program will display all of the Celsius to Fahrenheit degrees within that range which are divisible by 10.

C++ || Random Number Guessing Game Using Srand, Rand, & Do/While Loop

This is a simple guessing game, which demonstrates the use of srand and rand to generate random numbers. This program first prompts the user to enter a number between 1 and 1000. Using if/else statements, the program will then check to see if the user inputted number is higher/lower than the pre defined random number which is generated by the program. If the user makes a wrong guess, the program will re prompt the user to enter in a new number, where they will have a chance to enter in a new guess. Once the user finally guesses the correct answer, using a do/while loop, the program will ask if they want to play again. If the user selects yes, the game will start over, and a new random number will be generated. If the user selects no, the game will end.

C++ || Find The Prime, Perfect & All Known Divisors Of A Number Using A For, While & Do/While Loop

This program was designed to better understand how to use different loops which are available in C++.

This program first asks the user to enter a non negative number. After it obtains a non negative integer from the user, the program will determine if the inputted number is a prime number or not, aswell as determine if the user inputted number is a perfect number or not. After it obtains its results, the program will display to the screen if the user inputted number is prime/perfect number or not. The program will also display a list of all the possible divisors of the user inputted number via cout.
