Program Plan Intro

Decryption of the intercepted message

Program plan:

  • Include necessary header files.
  • Declare the namespace.
  • Declare the function “decrypt()”.
  • Define the function “decrypt()”.
    • Declare the necessary variables.
    • Use “for” loop to iterate the string length using the function “strlen()”.
      • Encode the string and assign the result into the variable “Encrypt”.
      • The “if” loop check the condition.
        • True, use the formula to decrypt the message.
      • Otherwise, use the formula to decrypt the message.
      • Assign the decrypted message into the variable “decode[i]”.
  • Define the “main()” function.
    • Declare and initialize the necessary variables.
    • Use “for” loop to iterate the number or key between “1” to “100”.
      • Call the function “decrypt()”.
      • Print the result.
    • Return “0”.
