i need c++ code to implement RSA Algorithm(Encryption and Decryption)

make sure that the program must print p and the Encryption and Decryption

here is the key generation n= p*q alpa(n) = (p-1) (q-1) d = e^-1 mod alpa (n)

make sure the code is working and print the right Encryption and Decryption (it must be a code )

so please make sure its working before you solve it ) note that Encryption and Decryption are Letters, not numbers
