PartI: Programming Write a C++ program that uses a while statement to determine and print the largest number of 10 numbers from the user input. Your program should use three variables as follows: 1. counter: A counter to count number: The current number input; largest: The largest number found; Write a program that reads a set of floating-point data values. Use a sentinel- controlled while loop to end entering data values. When all values have been read. print out the following formula for calculating standard deviation. 2. count of the values, the average, and the standard deviation. Use the 3. Write a program that estimates the value of the Euler number e using the formula: I! 2! 3! Prompt the user for the desired accuracy of e (that is the desired number of terms in simulation, such as 10)
