- 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.Write function headers for the following:a. A function named check() that has three parameters. The first parameter should accept an integer number, and the second and third parameters should accept a double-precision number. The function returns no value.b. A function named findAbs() that accepts a double-precision number passed to it and returns its absolute value.c. A function named mult() that accepts two floating-point numbers as parameters, multiplies these two numbers, and returns the result.d. A function that produces a table of the numbers from 1 to 10, their squares, and their cubes. No arguments are to be passed to the function, and the function returns no value.e. Write a function named rightTriangle() that accepts the lengths of two sides of a right triangle as the arguments a and b. The function should determine and return the hypotenuse, c, of the triangle. (Hint: Use Pythagoras’ theorem, c2=a2+b2)
- In this lab, you complete a partially written C++ program that includes two functions that require a single parameter. The program continuously prompts the user for an integer until the user enters 0. The program then passes the value to a function that computes the sum of all the whole numbers from 1 up to and including the entered number. Next, the program passes the value to another function that computes the product of all the whole numbers up to and including the entered number. The source code file provided for this lab includes the necessary variable declarations and the input statement. Comments are included in the file to help you write the remainder of the program. #include <iostream> #include <string> void sums(int); void products(int); using namespace std; int main() { double number; cout << "Enter a positive integer or 0 to quit: "; cin >> number; while(number != 0) { // Call sums function…In C++ just do the problem in simple, not complicated code. Even if a problem does not directly tell you to use a function, you should aim to do so regardless. The prime factors of 13195 are 5, 7, 13 and 29.What is the largest prime factor of the number 9003? Create a function called Nevada where you pass in the number as an argument and return the largest factor.Write a function prototype for a function named my_function that accepts two integers (a,b) as parameters and returns a integer? (C++)
- IN 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.Usin C++, write the definition of a function that takes as input the three numbers. The function returns true if the first number to the power of the second number equals the third number; otherwise, it returns false. (Assume that the three numbers are of type double).Write a c++ program that contains a “main” and 4 functions: In the main function declare 4 integer variables x, y, z and m and call the following functions: The first function is to initialize the 4 variables using the last 4 digits of your university ID number. For example, if your ID number is 43956789 then you x=6, y=7, z=8, and m =9. The second function should calculate and print the average of the 4 variables. The third function is to find the largest number of the 3 variables. The last function should double the values of the 4 variables. For example if x = 6 then x will become 12.
- Write a function in c++ language that determines if a number is prime. Use this function in a program that determines and prints all the prime numbers between 1 and 10,000. Do the required commented changes in the following program codeIn C++ just do the problems in simple, not complicated code. Even if a problem does not directly tell you to use a function, you should aim to do so regardless. 1. Create a function that takes in a number n and outputs all the odd numbers from 1 to n. 2. Create a function that takes in a int number and outputs each of the digits backwards 3. Create a function that counts backwards from 100 to 1. 4. If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.Find the sum of all the multiples of 3 or 5 below 1000. Use a function to do this. Return the total to main.Write a C++ program that calculates the average of a group of test scores, where the lowest score in the group is dropped. It should use the following functions: void getScore() should ask the user for a test score, store it in a reference param- eter variable, and validate it. This function should be called by main once for each of the five scores to be entered. void calcAverage() should calculate and display the average of the four highest scores. This function should be called just once by main and should be passed the five scores. int findLowest() should find and return the lowest of the five scores passed to it. It should be called by calcAverage, which uses the function to determine which of the five scores to drop. **DO NOT USE AN ARRAY OR GLOBAL VARIABLES!!!*** YOU MUST USE THE STATED FUNCTIONS. AND INPUT VALIDATION. For FULL CREDIT DISPLAY THE LOWEST SCORE WITH GOOD OUTPUT DESCRIPTION you MUST USE function prototyping.. DO NOT ACCEPT SCORES LESS THAN 0 OR GREATER THAN…
