- Assume userName and input are String variables. Write an expression that tests them for equality.JAVA PLEASEYour program will prompt the user for the following information: current population number of yearly births from the previous year number of yearly deaths from the previous year number of years into the future for your predictive value of the future population. You will then compute the following: birth rate death rate growth rate the predicted future population Assignment Notes: To allow the user to input the numeric data (such as current population) it is necessary to use the input function. The input function takes a string in parenthesis that prompts the user what to enter. The computer then waits until the user types a response, terminated by the user typing the Enter key. A string, as a sequence of characters, is returned to the variable on the lefthand side of the assignment statement. For example: currPopulation = input(“Enter the current US population”) The data in currPopulation is a string (because that is what the input statement does) but we need it to be a number…Lab Activity for the students: Exercise 5: Write a program that asks the user to input a letter. The program finds and prints if the letter is uppercase or lowercase. Then, the program asks the user to input a string and get a three-character substring from the beginning of the string. (1 Mark ) Example : If the inputs are 'y' and "Community". Then, the program will print: y is lowercase The substring is: Com
- Function strlen() takes a string as an argument and returns the number of characters in the string, Which of the following is the correct answer to fill the above statement with it? Select one: a. Spaces are not included in the length calculation b. Null character is not included in the length calculation c. Numbers are not included in the length calculation d. Null character is included in the length calculationBriefly describe each of the following string object methods: InsertprintTodaysDate is a function that accepts no parameters and returns no value. Write a statement that calls printTodaysDate.
- Assume the variable s has been assigned a string. Write code that displays "stop" if s is equal to "end". Otherwise, display "go".Exercise I- Medicine Write a program that asks the user to enter the name of the medicine (t for ThroX, f for FeliX), his mass. The user should enter as well if he has a prescription or not. The program will calculate the dosage using: age and his ThroX without prescription -The max dosage should be 0.75 mL -The dosage = mass / 150 -The number of pills per day to take is 1 ThroX with prescription -The dosage =mass * 3 / 150 -The number of pills per day to take is 5 FeliX with prescription -The dosage = 0.77 mL FeliX without prescription -The dosage should be between 0.3 and 0.7 -The dosage = mass * 0.009 -The number of pills per day to take is 2 -The number of pills per day to take is 6 The program should display the dosage and the number of pills to be taken per day if the requirements are full filled, otherwise it display "Please check your doctor for a prescription". In case the medicine does not exist in the database, the program display “Your medicine is not in our database!"…c# Danielle, Edward, and Francis are three salespeople at Holiday Homes. Write an application named HomeSales that prompts the user for a salesperson initial (D, E, or F) input as a string. Either uppercase or lowercase initials are valid. While the user does not type Z, continue by prompting for the amount of a sale. Issue the error message "Sorry - invalid salesperson" for any invalid initials entered. Keep a running total of the amounts sold by each salesperson. After the user types Z or z for an initial, display each salesperson’s total, a grand total for all sales, and the name of the salesperson with the highest total unless there is a tie. If there is a tie, indicate this in the program's output with the message: "There was a tie". An example of the program is shown below: Enter a salesperson initial >> D Enter amount of sale >> 10 Enter next salesperson intital or Z to quit >> d Enter amount of sale >> 2 Enter next salesperson intital or Z to quit…
