Program Plan Intro

Program Plan:

  • Include the appropriate headers into program.
  • Declare and define the constant variable “LEN”.
  • Declare the appropriate functions.
  • Define the “main()” function.
    • Declare the array variable “arr[]” in type of double.
    • Declare the variables “stdDeviation” and “avg” in type of double.
    • Declare the variable “ans” in type of character.
    • Using “do…while” loop, prompt the user for array values.
      • Call the function “stdDev()” which passes array and size of array and store the result in “stdDeviation”.
      • Prompt and get the sentinel value from user.
      • Check the loop with condition for sentinel value.
    • Return “0” to called function.
  • Define the function named “stdDev()” which passes the arguments “arr[]” in type of character and “size” in type of integer.
    • Declare and initialize the “sumSquares” in type of “double”.
    • Call the function “average()” which passes array and size of array as arguments and stores the result in “avg” variable.
    • Using “for” loops, calculate the summation value.
    • Return the square root of summation value.
  • Define the function named “average()” which passes “arr[]” and “size”  as arguments.
    • Declare and initialize the “sum” in type of “double”.
    • Using “for” loop, calculate the total of array values.
    • Return the average of array values.

Write a C++ program that will count from 1 to 10 by 1. The default output should be 1, 2, 3, 4, 5, 6 , 7, 8, 9, 10 There should be only a newline after the last number. Each number except the last should be followed by a comma and a space. To make your program more functional, you should parse command line arguments and change behavior based on their values. Argument Parameter Action -f, --first yes, an integer Change place you start counting -l, --last yes, an integer Change place you end counting -s, --skip optional, an integer, 1 if not specified Change the amount you add to the counter each iteration -h, --help none Print a help message including these instructions. -j, --joke none Tell a number based joke.   So, if your program is called counter counter -f 10 --last 4 --skip 2 should produce 10, 8, 6, 4 Please use the last supplied argument. If your code is called counter, counter -f 4 -f 5 -f 6 should count from 6. You should count from first to last inclusively.…
