The following
const double PI= 3.14159;
double degrees, radians;
cout << "Enter an angle in degrees and I will convert it\n";
cout << "to radians for you: ";
cin >> degrees;
radians = degrees* PI / 180;
// Display the value in radians left-justified, in fixed-point
// notation, with four decimal places of precision, in a field
// seven spaces wide.

- code for this in C: In college, a student may get a grade of 1.0 (as the highest) to 5.0(lowest). Anyone who gets a Final Grade of at most 3.0 is considered a passing grade. Create a program that will ask the user to input a student's midterm grade and tentative final grade. After calculating the student's final grade using the formula below, main() will then call on DisplayStatus() to display if the student passed the subject or not.

The great circle distance between the twopoints can be computed using the following formula:d = radius X arccos(sin (x1) X sin(x2) + cos(x1) X cos(x2) X cos(y1 - y2))Write a program that prompts the user to enter the latitude and longitude of twopoints on the earth in degrees and displays its great circle distance. The averageradius of the earth is 6,371.01 km. Note you need to convert the degrees into radiansusing the Math.toRadians method since the Java trigonometric methods useradians. The latitude and longitude degrees in the formula are for north and west.Use negative to indicate south and east degrees. Here is a sample run: Enter point 1 (latitude and longitude) in degrees: 39.55 −116.25 ↵EnterEnter point 2 (latitude and longitude) in degrees: 41.5 87.37 ↵EnterThe distance between the two points is…arrow_forwardComputer Fundamentals and Programming 2 Write a program that determines a student’s grade. The program will accept 3 scores and computes the average score. Determine the grade based on the following rules: - If the average score is equal or greater than 90, the grade is A. - If the average score is greater than or equal to 70 and less than 90, the grade is B. - If the average score is greater than or equal to 50 and less than 70, the grade is C. - If the average score is less than 50, the grade is F.

- C-Program for blood pressure. The program (screenshot below) compares the systolic & diastolic measurements to output whether the blood is (low, ideal, pre-high, or high) The code I wrote is able to successfully determine the blood pressure type as long as it lies within the same range. However, if it goes outside that range it prints an error. FOR EXAMPLE**** PLEASE READ*** If the user inputs their systolic variable as 100 and their systolic as 90, it will print an error. If the systolic & diastolic measurements are vastly different the program prints an error, if you could help resolve this issue it would be greatly appreciated.arrow_forwardQuestion # 4: Write a program that calculates the electricity bill. The rates of electricity per unit are as follows: If the units consumed are 300 and 8 2000 2750 Question # 6: Write a program that converts the angle from degree to radian and displays each value.arrow_forwardYour 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…arrow_forward
- C CODE PLEASE 3.28 Fixed LAB: Warm up: Automobile service cost (1) Prompt the user for an automobile service. Each service type is composed of two strings. Output the user's input.Ex: Enter desired auto service: Oil change You entered: Oil change (2) Output the price of the requested service. Ex: Enter desired auto service: Oil change You entered: Oil change Cost of oil change: $35 The program should support the following services: Oil change -- $35 Tire rotation -- $19 Car wash -- $7 If the user enters a service that is not listed above, then output the following error message: Error: Requested service is not recognizedarrow_forwardc## please Write a Console Application that reads two integers, determines whether the first is a multiple of the second and displays the result.

- Problem: Feed Nibble Monster Till Full Write a program that generates a number in [0, 500] at the beginning -- this corresponds to how hungry the monster is -- and keeps asking the user to feed the monster until that number falls to zero. Each time the user feeds the monster a nibble, hunger decreases by the decimal value of the character (i.e. if the user feeds 'A' hunger decreases by 65). But when the user feeds the monster some character that isn't a nibble, the hunger increases by the decimal value of the character (since puking depletes energy). Use while loop. Sample runs: Notice the loop exits after one iteration, because hunger was very low and one nibble made the monster full: Notice hunger increasing after non-nibble (pink highlight): Notice that the program just keeps going when the user feeds the monster only non-nibbles. Do you think the program will keep running forever if the user never gives the monster nibbles?arrow_forward(Temperature Conversions) Write a program that converts integer Fahrenheit temperaturesfrom 0 to 212 degrees to floating-point Celsius temperatures with 3 digits of precision. Perform thecalculation using the formulacelsius = 5.0 / 9.0 * (fahrenheit - 32);The output should be printed in two right-justified columns of 10 characters each, and the Celsiustemperatures should be preceded by a sign for both positive and negative values.arrow_forwardThe owners of the Annan Supermarket would like to have a program that computes the weekly gross pay of their employees. The user will enter an employee’s first name, last name, the hourly rate of pay, and the number of hours worked for the week. In addition, Annan Supermarkets would like the program to compute the employee’s net pay and overtime pay. Overtime hours, any hours over 40, are paid at 1.5 the regular hourlyrate. Net pay is gross pay minus taxes (Refer to the tax table on the second page).Define a class called Employee. The class must have private attributes to store the employee's name, hourly rate, and regular (≤ 40) and overtime hours worked. The class must also have methods to perform the following tasks:• A constructor to initialize the hourly rate to the minimum wage of $7.25 per hourand the hours worked (regular and overtime) to 0.0.• A method to get (a setter/mutator method)⬧ the employee's name⬧ the hourly rate⬧ the hours work for the month (by the week – assume 4…arrow_forward
