You are tasked to create an encryption program which takes a key word. The keyword will fill the first part of the shifted array. The remaining letters will fill the end of the array. It should look like this:

You should have an interactive menu with the following options:
1 Enter Key word //takes new key word and re-aligns shifted array
2 Encrypt message//takes a message of 140 characters and encrypts message
3 Decrypt message//takes an encrypted massage of 140 characters and decrypts it
4 Quit//exits program;
A couple tips:
Use the copy function from the library not the library. If you use the algorithm library you need to make a change in visual studios precompiler settings or you will get an error. You cannot assign arrays using the ‘=’ operator; only individual indices of the array can be assigned this way.
Take one case or the other for input. All Caps or all lowercase. You can use “toupper()” to set all letters to upper case: http://cpp.sh/7gwx
/* toupper example */
#include
#include
#include //for toupper
using namespace std;
int main ()
{
int i=0;
char str[]="Test String.\n";
char c;
while (str[i])
{
c=str[i];
str[i]=toupper(c);
i++;
}
