Solve in C$++$ and write a program to encrypt and decrypt

Encrypt the plaintext $x=x_1||x_2||x_3=10100111||10101010||10100111$ using the block modes

ECB, CBC$,$ CFB$,$ OFB, CTR where the blockcipher is defined as two rounds of Feistel with

$f(R,K_i)\frac{?}{b}=ar(R)o+K_i,$ key $K_1=0111$ for the first round, and key $K_2=1010$ for the second

round. Use $IV=01001100$ in all cases.
