Transcribed Image Text:2. Write a simple encryption/decryption program. Function encrypt takes a character
pointer as a parameter and uses pointer-subscript notation to change the value in the
address pointed to by adding 1 to it. Function decrypt takes a character pointer as a
parameter and uses pointer notation to change the value in the address pointed to by
![subtracting 1 from it. Function main calls functions encrypt and decrypt and prints the
encrypted string.
//
#include "stdafx.h"
A simple encryption/decryption program
#include <iostream>
using namespace std;
// write the prototype for function encrypt
// write the prototype function decrypt
int main()
{
// create a string to encrypt
char string[] = "this is a secret!";
cout <« "Original string is
: "
« string <« endl;
encrypt(string);
cout <« "Encrypted string is : " <« string << endl;
decrypt(string);
cout <« "Decrypted string is : " <«string<< endl;
return 0;
}
// encrypt data
void encrypt(char e[])
{
// Write implementation for function encrypt
} // end function encrypt
// decrypt data
void decrypt(char *ePtr)
{
// Write implementation for function decrypt
} // end function decrypt
Sample output
