Write a C/C++ system program to move a file from one folder to another in the Windows file system.

In the event that you delete a file by mistake and subsequently need access to it again, what steps should you take?

Before you use a file extension, you should make sure you are familiar with what it is and what function it serves in the context of your work.

Create a C++ Program to do the following: Create a .txt file with up to 10 double numbers. Then in your code, create an array to hold 10 doubles. Openthe file. Read each number from the file into a place in the array. Count how many numbers you read. Close thefile.Now, go through the data in the array twice. Don’t go through all 10 elements in the array, only the elementsfor which you have read data. On the first pass, calculate the average of the numbers in the array. (Calculate thetotal, divide by count, that is µ).On the second pass through the data, for each number you should calculate how far it is from the average(number - average), square that, and keep a sum of the squares, that is S.When you’re done, calculate the average of that sum of squares, A. The square root of that number, σ is yourstandard deviation.Print out the average µ and standard deviation σ
