The expected number of strokes varies from hole to hole and is called par (possible values: 3, 4, or 5). Each score's name is based on the actual strokes taken compared to par: "Eagle": number of strokes is two less than par "Birdie": number of strokes is one less than par "Par": number of strokes equals par "Bogey": number of strokes is one more than par Given two integers that represent the number of strokes used and par, write a program that prints the appropriate score name. Print "Error" at the end of the output if par or score is not in the expected range.

- The number of permutations of a set of n items taken r at a time is given by the followingformulan!/r!(n−r)!: where n! is the factorial of n, r! is the factorial of r, and (n-r)! is thefactorial of the result of n-r. The factorial of a number n can be solved using the followingformula: n!=e−nnn√ 2πn.If there are 18 people in your class and you want to divide the class into programming teams of 3members, you can compute the number of different teams that can be arranged using this formula(n!/r!(n−r)!).Write a C++ program that determines the number of potential team arrangements. You will needto use the double type for this computation. Use the Lab Template you set-up last week, properformatting, and appropriate comments in your code. The output must be labeled clearly andformatted neatly.What is the probability that in a classroom of x people, at least 2 will be born on the same day of the year, ignoring leap year?
