Lab Exercises: 1. Write a script that will generate a random number between 1 and 20 and the user needs to guess that number. If the user enters a wrong number, print a message that indicates that. The user needs to keep trying until the user guesses the right number. Once the user guesses the right number, the program needs to stop and print a message telling the user that he/she guessed the number. 2.

- 4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }5. A prime number is a number that is only evenly divisible by itself and 1. For example, the number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, how- ever, is not prime because it can be divided evenly by 1, 2, 3, and 6. Write a Boolean function named is_prime which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Use the function in a program that prompts the user to enter a number then displays a message indicating whether the number is prime. 6. In another program, use the function you wrote in question 5 to print the prime numbers between 1 and 100 using for loop.1. A prime number is a number that is only evenly divisible by itself and 1. For example, the number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6.Write a Boolean function named is_prime which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Use the function in a program that prompts the user to enter a number then displays a message indicating whether the number is prime.Tip:Recall that the % operator divides one number by another and returns the remainder of the division. In an expression such as num1 % num2, the % operator will return 0 if num1 is evenly divisible by num2.
- A county collects property taxes on the assessment value of property, which is 60 percent of the property’s actual value. For example, if an acre of land is valued at $10,000, its assessment value is $6,000. The property tax is then 72¢ for each $100 of the assessment value. The tax for the acre assessed at $6,000 will be $38.40. Write a function that accepts the actual value of a piece of property and displays the assessment value and property tax. JavaScriptA particular talent competition has 5 judges, each of whom awards a score between 0 and 10 to each performer. Fractional scores, such as 8.3, are allowed. A performer’s final score is determined by dropping the highest and lowest score received, then averaging the 3 remaining scores. Write a program that uses these rules to calculate and display a contestant’s score. It should include the following functions: • void getJudgeData() should ask the user for a judge’s score, store it in a reference parameter variable, and validate it. This function should be called by main once for each of the 5 judges. • double calcScore() should calculate and return the average of the 3 scores that remain after dropping the highest and lowest scores the performer received. This function should be called just once by main and should be passed the 5 scores.Two additional functions, described below, should be called by calcScore, which uses the returned information to determine which of the scores to drop.•…Write a function that returns the number of days in a year using the following header:def numberOfDaysInAYear(year):Write a test program that displays the number of days in the years from 2010 to 2020.
- printTodaysDate is a function that accepts no parameters and returns no value. Write a statement that calls printTodaysDate.Project 5 Please write a program that computes the average of 3 exam scores of 3 students. It first asks the user three exam scores for each student and then compute the average of them. The program should have the following functions. • int getTestScore(): This function is called by main function. It asks the user to enter the score of the exam. Once it gets a user input data, the function returns it to the main function. Input Validation: Please check if the entered score is between 0 and 100 inclusive (considered valid). If not, repeat asking to enter a valid score. • double calAverage(int, int, int, int, int): This function is called by main function. It calculates the average of 3 exam scores passed from main function in int data type. Once the function calculates the average, it returns it to main function in double data type. • void display(string, double): This function is called by main function and displays the student’s name and average exam score. The arguments are…Create a function that takes a number as an argument and returns "Fizz", "Buzz" or "FizzBuzz" If the number is a multiple of 3 the output should be "Fizz" • If the number given is a multiple of 5, the output should be "Buzz" If the number given is a multiple of both 3 and 5, the output should be "FizzBuzz" ● • If the number is not a multiple of either 3 or 5, the number should be output on its own as shown in the examples below. • The output should always be a string even if it is not a multiple of 3 or 5. Examples fizz buzz (3) → "Fizz" fizz buzz (5) → "Buzz" fizz buzz (15) ➡ "FizzBuzz" fizz buzz (4) "4" (Ctrl)
- Convert radians into degrees Write a function in Python that accepts one numeric parameter. This parameter will be the measure of an angle in radians. The function should convert the radians into degrees and then return that value.PHP ATM machines allow 4 or 6 digit PIN codes and PIN codes cannot contain anything but exactly 4 digits or exactly 6 digits. *With user input ($pinNumbers), create a function that takes a string and returns true if the PIN is valid and false if it's not. Examples validatePIN("$1234") ➞ true validatePIN("12345") ➞ false validatePIN("a234") ➞ false validatePIN("") ➞ false Notes ● Some test cases contain special characters. ● Empty strings must return false.Write a function to display a pattern as follows: 12 13 2 1 ...n n-1 ... 3 2 1The function header isdef displayPattern(n):Write a test program that prompts the user to enter a number n and invokes displayPattern(n) to display the pattern.
