Write a C++ program to perform 128-bit encryption and decryption using XOR operation.
Your program must ask for 128-bit key and plain text then perform encryption and decryption.
The information about colours is to be stored in bits of a variable called colour. The bit
number 0 to 7, each represent 8 colours of a rainbow, i.e. bit 1 represents Blue, 2 represents Green,
and so on (see table below). Write a C++ program that asks the user to enter a number and based on
this number, an eight lined rainbow (of asterisks *) is to be displayed, such that, if the bit is ON,
respective colour is displayed otherwise black line is drawn (not visible).
