Objectives: practice with math, while-loops, sentinels, input validation, functionsStarting with the provided file circles.py, write a program that uses functions to computethe area and circumference of a circle of a user-specified radius.The program consists of a main () function and two other functions, as follows:main (): Asks the user for the radius of a circle (floating point number). If the user enters aradius of zero, the program prints “Goodbye!" and ends. If the user enters a negative radius,the program prints “Invalid radius!", and asks again for a radius, and keeps asking until theuser enters zero or a positive number. If the user enters a positive number, the program callsthe two other functions and prints: A circle of radius R has circumference C and area A.(where R is the radius number, C is the calculated circumference, and A is the calculatedarea.) After printing the circumference and area, the program asks again for a new radius.[20 pts]circumference (r) : Takes a radius r as a parameter and computes and returns thecircumference of the circle, using the math formula 2nr (Note: this function does notprint anything.) [15 pts]area (r): Takes a radius r as a parameter and computes and returns the area of the circle,using the math formula rr? (Note: this function does not print anything.) [15 pts]The provided starter program imports Python's math module, which provides an accuratevalue for pi in the pre-defined variable math.pi.

(Numerical) a. The following is an extremely useful programming algorithm for rounding a real number to n decimal places: Step 1: Multiply the number by 10n Step 2: Add 0.5 Step 3: Delete the fractional part of the result Step 4: Divide by 10n For example, using this algorithm to round the number 78.374625 to three decimal places yields: Step1:78.374625103=78374.625 Step2:78374.625+0.5=78375.125 Step3:Retainingtheintegerpart=78375Step4:78375dividedby103=78.375 Using this algorithm, write a C++ function that accepts a user-entered value and returns the result rounded to two decimal places. b. Enter, compile, and run the program written for Exercise 11a.
Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)
(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.

2. Test Scores File: test_scores.py Write pseudocode for the main() part of a program that asks the user to enter 4 test scores between 0 and 100, then displays a JCU grade for each score and also the average test score. When you have written the pseudocode for main, implement your solution in Python code and test it with a range of meaningful data. Remember that we've done the JCU grades question before, so copy your function from that practical code file. Sample Output Score: 3 Score: 50.5 Score: 66 Score: 100 Score 3.0, which is N Score 50.5, which is P Score 66.0, which is C Score 100.0, which is HD The average score was 54.875 Enhancements When you have that working... We asked for 4 scores. Have a look at your code... did you use 4 as a numeric literal or a constant?Change 4 to 3... Did you have to change the program in more than one place?If so, then you've missed one of the things we've taught...As a strong guideline: if you need to use the same literal more than once, you…
Language: Python A particular talent competition has 5 judges, each of whom awards as 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: -getJudgeData() should ask the use for a judge's score, store in a parameter variable, and validate it. This function should be called by main program once for each of the 5 judges. -calcScore(score1, score2, score3, score4, score5) 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…
Functions & Loops : Case Studies Prompt the user to input two positive integers. Variables: firstNum and secondNum (firstNum must be less than secondNum) (use while loop); create a user-defined function called validateUserInput() to validate the user's input. Use Call-by-Value. validateUserInput() is a value returning function. Output all odd numbers between firstNum and secondNum. (use while loop); create a user-defined function called oddNumbers(). Use Call-by-Value. oddNumbers() is a void function. Output the sum of all even numbers between firstNum and secondNum. (use while loop); create a user-defined function called sumEvenNumbers(). Use Call-by-Value. Declare a variable called sumEven in the main() for the sumEvenNumbers(). sumEvenNumbers() is a value returning function. Use sumEven to hold a returned value. Output the numbers and their squares between 1 and 10. (use while loop): create a user-defined function called displaySquareNumbers(). Call-by-Value.…

Assignment Write a program to calculate n! for a given number n and perform the simple calculator operations. The valid operations of the calculator are: + add - sub * mul I div The program must contain a function fact with one input parameter that returns the factorial of a number, a function add that performs the addition of two numbers, a function sub that performs the subtraction of two numbers, a function mul that performs the multiplication of two numbers, a function div that performs the division of two numbers. The program must also check for bad input data. Make sure when you pass parameters you pass the addresses (not the value). • All function return type must be of type void. • Take inputs in main function. • Pass the addresses of the operands and the address of the result to each function. Output must be displayed as follows: 1: Addition 2: Subtraction 3: Multiplication 4: Division 5: Factorial 6: Quit Enter the choice => 1 Enter two numbers => 2, 3 Sum => 5
