Question is in the picture below:

Please explain using \\comments in the program, thank you!

2) The value of can be approximated with the Gregory-Leibniz series: 2n+1 + 2n+1) Write a program that will approximate the value of using the above series evaluated at N terms. Your program should ask the user to enter how many terms to use in the approximation. Draw a flowchart for how your loop functions. Your program will undoubtedly require using a loop to approximate for an arbitrary N number of terms. Notice that the sign of each successive term alternates from positive to negative. As you approach this problem, ask yourself the following questions: a) b) c) d) What's the general pattern to calculate each term at a given n? What value does n start at? Are the terms positive when n is even, or when n is odd? What code can I write to check if n is even or odd each time through the loop
