Write a C++ function factorial that takes an integer, n, and returns the value of n factorial (a.k.a., n!): When n is positive, n! = 1 * 2 * 3 * ... * n. For example, 5! = 1 * 2 * 3 * 4 * 5 = 120. When n is zero, n! is defined to be 1. When n is negative, n! is undefined. You may assume that the parameter n will not be negative for this problem.

In C++ write a program that generates three random numbers and then find the min number among the generated values, using these three functions: void getrandnum(int &n1, int &n2, int &n3), int findMin(int n1, int n2, int n3), and void printResult(int n1, int n2, int n3, int min). Make the main function drive all these functions.

In C++ Define a function named CoinFlip that returns "Heads" or "Tails" according to a random value 1 or 0. Assume the value 1 represents "Heads" and 0 represents "Tails". Then, write a main program that reads the desired number of coin flips as an input, calls function CoinFlip() repeatedly according to the number of coin flips, and outputs the results. Assume the input is a value greater than 0. Hint: Use the modulo operator (%) to limit the random integers to 0 and 1. Ex: If the random seed value is 2 and the input is: 3 the output is: Tails Heads Tails Note: For testing purposes, a pseudo-random number generator with a fixed seed value is used in the program. The program uses a seed value of 2 during development, but when submitted, a different seed value may be used for each test case. The program must define and call the following function:string CoinFlip()
In 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.

Please help with this lisp function and provide photos so it's easier to read the code
in c++. Write the definition of function int integerCubeRoot(int n). The function returns the biggest integer whose cube is less than or equal to n. Absolutely no function calls e.g. to a <math> function. Just basic operations like * and + etc. BTW you can cube a number just using basic multiplication.

Write a C++ program to calculate a rectangle's area. The program consists of the following function: getLength – This function should ask the user to enter the rectangle's length, and then returns that value as a double getWidth – This function should ask the user to enter the rectangle's width, and then returns that value as a double. getArea – This function should accept the rectangle's length and width as arguments and return the rectangle's area. • displayData – This function should accept the rectangle's length, width and area as arguments, and display them in an appropriate message on the screen. main – This function consists of calls to the above functions.
In C++ Even if a problem does not directly tell you to use a function, you should aim to do so regardless. 2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder. What is the smallest positive number that is evenly divisible by all of the numbers from 1 to 20?
