Chapter 7, Problem 14E

7.10

Program Plan Intro

Modified version of the exercise 7.10 with the global variables:

Program Plan:

• Include required header files.
• Give the function prototype.
• Declare the variable “n” and “val” as global variable
• Define the main function,
  • Get the number from the user.
  • Call the function “prime()”.
  • Check whether “val” equals to “1”.
    • Print the corresponding statement.
  • Otherwise, if the condition fails,
    • Print the corresponding statement.
• Definition for the function “prime()”,
  • Declare the variable “i”.
    • Use for loop to check the condition.
      • Check whether the remainder equals to 0.
        • Return the value “0”.
      • Return the value “1”.

    • Condition to check if both the elements in the array are equal.
      • Return the value “0”.
  • Check whether “isTrans(A,B)” equals to 1.
    • For loop to check whether “k” is less than “5”
      • For loop to check whether “l” is less than “4”
        • Print the element.
      • Print new line.
    • Otherwise, print the corresponding statement inside “else” clause.
• Define the main function
  • Call the function “transpose()” by passing the array.
  • Return the value “0”.
