in arduino uno keypad, why did we use byte variable in declaring the number of rows and columns?
Step by step
Solved in 2 steps
- Programming in c++(visual studio 2019): I’m prompting the user to input “even odd or random” to start my code and noticed the while loop I use to check of the user input is valid or not freaks out if I go over the char limit I gave the user input. Can I fix this or do I just need to increase the input size?Using C++ How would I generate a random value for a random location in a multiplication table (printing the random value at a random row and column). Then you ask and read a row and column from the user and compare them with the generated row and column and tell if it’s right. We haven't learned functions. Just nested Loops Assignment: Write a program that prints the multiplication table but inserts a randomly generated incorrect value between 1 and 50 into a cell whose row and column are randomly selected. Make sure the program does insert an incorrect value. For example, if row and column of 3 and 4 are randomly selected, keep generating a random number to print for that location until it's not the right value of 12. Then, ask the user to tell where in the table the incorrect number is located by entering the row and column of the incorrect number. Print whether the user was right or not. If he or she was right, ask for and read the correct value; if not, the program must give the…Using C++ Program: A palindrome is a word that is spelled the same way both forwards and backwards. For example, the word, 'racecar' is a palindrome. Using character arrays, write a program that prompts the user to enter a word from the keyboard and informs the user whether the word is a palindrome or not.
- USE JAVA Write an application that allows a user to enter the names and birthdates of up to 10 friends. Continue to prompt the user for names and birthdates until the user enters the sentinel value ZZZ for a name or has entered 10 names, whichever comes first. When the user is finished entering names, produce a count of how many names were entered, and then display the names. In a loop, continuously ask the user to type one of the names and display the corresponding birthdate or "Sorry, no entry for name" if the name has not been previously entered. The loop continues until the user enters ZZZ for a name. An example of the program is shown below: Enter a name Lan Enter birthdate with slashes between the month, day, and year 12/25/1983 Enter a name or ZZZ to quit Marylouise Enter birthdate with slashes between the month, day, and year 2/20/1992 Enter a name or ZZZ to quit Arminda Enter birthdate with slashes between the month, day, and year 8/30/1992 Enter a name or ZZZ to quit Gudrun…One of your colleagues wanted to generate an List of strings using a random function, and since you are an expert in programming, your colleague asked you to create a program for him that generates random letters to make this desired string (I am a programmer) how can you help him to achieve this task ?

- Reza Enterprises sells tickets for buses, tours, and other travel services. Because Reza frequently mistypes long ticket numbers, Reza Enterprises has asked his students to write an application that shows if a ticket is invalid. Your application/program tellsthe ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you lose the last digit of the number, then divide by 7, the remainder of the division is exactly the same to the last dropped digit. This process is shown below: Step 1: Enter the ticket number; for example 123454 Step 2: Remove the last digit, leaving 12345 Step 3: Determine the remainder when the ticket number from step 2 is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4: Display a message to the ticket agent indicating whether the ticket number is valid or not.. Test your application with the following ticket numbers: - 123454; is a valid ticket number - 147103; is a valid ticket number -…solve in c++ Create an application for a supermarket owner.

Enter an item ID and price2. Retrieve the price of a specific item3. Display all items within a specific range of prices4. Delete an item5. Display all items6. Delete all itemsNote: The items should be stored in memory sorted based on price. The six tasks should be implemented as functions.The program should run continuously until the user presses 'e' to exitPlease solve this using java Write an application that allows a user to enter the names and birth dates of up to 10 friends. Continue to prompt the user for names and birth-dates until the user enters the sentinel value “ZZZ” for a name or has entered 10 names, whichever comes first. When the user is finished entering names, produce a count of how many names were entered, and then display the names. In a loop, continuously ask the user to type one of the names and display the corresponding birth-date or an error message if the name has not been previously entered. The loop continues until the user enters “ZZZ” for a name.
