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.

(Rounding Numbers) Function floor can be used to round a number to a specific decimal place. The statementy = floor(x * 10 + 0.5) / 10;rounds x to the tenths position (the first position to the right of the decimal point). The statementy = floor(x * 100 + 0.5) / 100;rounds x to the hundredths position (the second position to the right of the decimal point). Write a program that defines fourfunctions to round a number x in various ways:A. roundToInteger(number)B. roundToTenths(number)C. roundToHundredths(number)D. roundToThousandths(number)For each value read, your program should print the original value, the number rounded to the nearest integer, the number rounded to the nearest tenth, the number rounded to the nearest hundredth and the number rounded to the nearest thousandth.

- 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; }arrow_forwardUse the pseudocode description below to write a portion of a program that uses an if, else if, else decision structure that will determine if someone lives in Boston. 1. display message that describes what program will do. 2. ask the user to input an answer to the question: Do you live in Boston?. 3. if they entered 'y', display a message confirming that they live in Boston. 4. if they entered 'n' , display a message confirming that they don't live in Boston. 5. if they entered an invalid entry, display a message telling them.arrow_forwardQ2: (Financial: Compare cost) Suppose you shop for rice in two different packages.

- Answer this question Write a program that calculates and displays a person’s body mass index (BMI). The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height. A person’s BMI is calculated with the following formula:BMI = weight × 703 / height2where weight is measured in pounds and height is measured in inches. The program should display a message indicating whether the person has optimal weight, is underweight, or is overweight. A sedentary person’s weight is considered to be optimal if his or her BMI is between 18.5 and 25. If the BMI is less than 18.5, the person is considered to be underweight. If the BMI value is greater than 25, the person is considered to be overweightarrow_forwardPROGRAM LANGUAGE C PROGRAM In a course with 2 midterms and 1 final exam, you will write a code that determines the remainder and passer. The program will first say "Please enter the 1st midterm grade:" and when you enter from the keyboard, it will ask for the second exam and then the final grade. The effect of the first midterm grade will be 25%, the effect of the second visa grade will be 25% and the effect of the final exam will be 50%. If these three exams are calculated with the percentages given, the result will be "Passed the Course!" If it is 50 and above, and if it is below 50, "Failed from the Course" will be written.

- Ron bought several acres of farm to grow and sell vegetables. Suppose that Ron wants to grow a maximum of two types of vegetables. Write a program that prompts Ron or the user to do the following: Enter the total farm area in acres. The number of vegetables (one or two) that the user wants to grow. If the user wants to grow trwo types of vegetables, then specify the portion,as a percentage, of the farm land used for each type of vegetable. Enter the seed cost, plantation cose, fertilizing cost, labor cost, for each acre. Enter vegetable selling price per acre. Output the total revenue.

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_forwardUse C++ Programing language. Write a program that computes and displays the charges for a patient’s hospital stay. First, the program should ask if the patient was admitted as an inpatient or an outpatient. If the patient was an inpatient, the following data should be entered: The number of days spent in the hospital The daily rate Charges for hospital services (lab tests, etc.) Hospital medication charges If the patient was an outpatient, the following data should be entered: Charges for hospital services (lab tests, etc.) Hospital medication charges Use a single, separate function to validate that no input is less than zero. If it is, it should be reentered before being returned. Once the required data has been input and validated, the program should use two overloaded functions to calculate the total charges. One of the functions should accept arguments for the inpatient data, while the other function accepts arguments for outpatient data. Both functions should return the…arrow_forward
