Chapter 6, Problem 14PE

Program to display sum of square of the integer value of the string values

Program plan:

• The function named “toNumbers()” is defined and inside the “toNumbers()”,
  • Initialize the for loop that ranges till the length of the array
    • The variable “strList[]” stores the integer value of the string values in the array.
    • Return the value stored in the variable “strList”
• The function named “squareEach()” is defined and inside the “squareEach()”,
  • Initialize the for loop that ranges till the length of the array
    • The required variable is declared and stores the array of numbers that have been squared.
    • Return the value stored in the variable “num”
• The function named “sumList()” is defined and inside the “sumList()”,
  • Declare the required variable
  • Initialize the for loop that ranges till the length of the array
    • The variable “y” stores the sum of the numbers in the array.
    • Return the value stored in the variable “y”
• In the “main()” function,
  • Generate a prompt to take the user input.
  • Open the text file from which the contents have to be taken as input.
  • Declare the required array variable.
  • Initialize a for loop to read the lines from the file as user input.
  • Call the method named “toNumbers()” to get the integer value of the string.
  • Call the method named “squareEach()” to square the numbers in the given array.
  • Call the method named “sumList()” to square the numbers in the given array.
  • Print the output value stored in the variable “z”.
• Call the function “main()”.
