- (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.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)Explain why it's okay for a function to have side effects on occasion.
- How can we pass argument to a function by reference instead of pass by value?Create a function in C language that takes two integers x, and y as the parameters and returns the sum and the absolute difference of both the numbers but the return type of the function should be void. You can add extra parameters to the function but the function should not return anything and should send the required values as well. Test your function for the numbers 10, and 5 inside the main function.What does it mean to provide parameters to a function in the right order when it accepts more than one?
- This is c programming question. Use function please for solving. Question: (The function that returns letter grade according to midterm and final grade) : The function turn_to_letter decides on the letter grade of the student according to the table below from the visa and final grades sent into it and returns it, write it together with a main function which the turn_to_letter function is called and prints the letter equivalent on the screen. - Success score = 40% of midterm + 60% of final, - F for the success score below 50, D for between 50 and 59, C for between 60 and 69, B for between 70 and 79, A for 80 and above.C Programming Problem : Write a C program with a function that takes an integer value (1 <- integer value < 9999) and returns the number with its digits reversed. For example, given the number 6798, the function should return 8976. Those two- original number and reversed number- numbers will pass to another function as parameters and calculate their sum. The program should use the function reverseDigits to reverse the digits and SumOriginalReverse to calculate their sum. Your output should appear in the following format: Output reverse digiS 4321 Main Enter a number between 1 and 9999: 6798 The number with its digits reversed is: 8976 6798 + 8976 - 15774 12.34 JomoriginalRevers Enter a number between I and 9999: 6655 The number with its digits reversed is: 5566 6655 + 5566 = 12221 Enter a number between 1 and 9999: 8 The number with its digits reversed is: 8 8 + 8 = 16 Enter a number between 1 and 9999: 123 The number with its digits reversed is: 321 123 + 321 = 444 Enter a number…In a function call, you can't have keyword and non-keyword parameters.
- What roles do the parameters and the return statement play in a function definition?Create a function in C++ that returns the century depending on the year given as a parameter. Sample Input1993 Sample Output20 HintYou need to divide 1996 by 100: 1996/100 = 19.96, then round it to the nearest integer, which is 20 in this caseIN C programming Write a function that will take an integer as an argument and return the factorial of the integer. Then write another function that will take two integers as arguments and then return the ratio of the factorials of the first argument with the second one. You need to make two calls to the first function inside the second function to find the factorials of the numbers.
