- 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) Heron’s formula for the area, A, of a triangle with sides of length a, b, and c is A=s(sa)(sb)(sc) where s=(a+b+c)2 Write, test, and execute a function that accepts the values of a, b, and c as parameters from a calling function, and then calculates the values of sand[s(sa)(sb)(sc)]. If this quantity is positive, the function calculates A. If the quantity is negative, a, b, and c do not form a triangle, and the function should set A=1. The value of A should be returned by the function.Hi please Solve in c language. (Wattan Corporation) is an Internet service provider that charges customers a flat rate of $7.99 for up to 10 hours of connection time. Additional hours or partial hours are charged at $1.99 each.Write a function charges that computes the total charge for a customer based on the number of hours of connection time used in a month. The function should also calculate the average cost per hour of the time used (rounded to the nearest 0.01), so use two output parameters to send back these results.You should write a second functionround_money that takes a real number as an input argument and returns as the function value the number rounded to two decimal places. Write a main function that takes data from an input file usage.txt and produces an output file charges.txt. The data file format is as follows:Line 1: current month and year as two integersOther lines: customer number (a five-digit number) and number of hours usedHere is a sample data file and the…
- c++ You are implementing a function that checks the value of the following variable of type char Number of Living Parents, from 0 to 2. Without using IFs or Switches (only use bitwise operators) create the following function that returns the result in integer for this variable: int getNumberChildren (char PersonByte);Question: thanks Write a function called calculateFactorial that takes a positive integer n as input and returns the factorial of n. The factorial of a non-negative integer n is the product of all positive integers less than or equal to n. Example: Input: 5 Output: 120 Explanation: calculateFactorial(5) should return 5 * 4 * 3 * 2 * 1, which equals 120. Remember, the factorial of 0 is defined to be 1. Ensure. Please help.Hi Asap. Thanks Write a function called calculateFactorial that takes a positive integer n as input and returns the factorial of n. The factorial of a non-negative integer n is the product of all positive integers less than or equal to n. Example: Input: 5 Output: 120 Explanation: calculateFactorial(5) should return 5 * 4 * 3 * 2 * 1, which equals 120. Remember, the factorial of 0 is defined to be 1. .

- Hello, I am having trouble with this homework question. We are covering the topic Function 2. 3.)Given the following functions: #include<iostream>using namespace std; void increment(int x, int y) {x+=y;} int main() {int n=10, amount = 5;increment(n,amount);cout << n << "\n";return 0;} 1. Explain the problem with the increment function. 2. Explain how to fix the problem without changing the main function.C++ Fix the broken code, Fix the function that is being used It does not charge the full hour for fractional portions. If you enter 4.5 it will return 27.50 as opposed to 30. Instructions to fix the code Consider this…. Charge will never be less than 20 so…… double charge = 20; for hours above 3…. If (hours >3) charge = 20 + ceil(hours -3)*5; where ceil brings it up to the next full hour value…. The charge will never be greater than 50 so….. If (charge > 50) charge = 50; now all you need to do is return charge Here is the code: #include<iostream>#include<iomanip>using namespace std;/* This is a function that calculates the charge of parking for the given amount of time (in hours) */double calculateCharges(double hours) {if (hours <= 3.0) { // If the time is less than 3 hours.return 20.0; // Charge a fixed amount of $20}else {double charge = 20.0 + (hours - 3.0) * 5; // Calculate the charge, which is $20 + ($5/hour for excess of 3 hours)if (charge >= 50.0) {…(C PROGRAMMING ONLY) DO NOT EDIT THE MAIN 7. Special Exchanging Giftsby CodeChum Admin It's Christmas time and we're having this exchanging gifts activity! I want to surprise the receiver of my gift. After he/she receives my gift, I will add an additional P100 bill! Instructions: In the code editor, you are provided with a main() function that asks the user for 2 integers. Then, a function call to a function named, exchangeGift() is made and the addresses of the 2 integers are passed.This exchangeGift() function hasn't been implemented yet so this is your task. This has the following description:Return type - voidName - exchangeGiftParameters - 2 addresses of 2 integersDescription - swaps the value of the 2 integers and then adds 100 to the 2nd integer (or 2nd parameter)DO NOT EDIT THE MAINInput 1.
