Hello,

Please message for rest of the code. Chegg has determine that the post is too long.

My c++ program isn't producing the correct result. The least few output isn't computing properly. Please help me fix my code so that last few lines will look like the following:

$$$$Use eapp3 and dapp3 to test the program.$$$$

Call eapp3 to display its data.

The original data is: 4 5 6 0. The encrypted data is: 3 7 1 2.

Get encrypted data from eapp3 and use the data on the dapp3 to test program.

The original data is: 1743. The decrypted data is: 7640.

The original data is: 1 7 4 3. The encrypted data is: 0 4 6 7.

$$$$Use eapp6 and dapp6 to test the program.$$$$

Call dapp6 to display its data.

The original data is: 0 0 0 0. The encrypted data is: 0 0 0 0.

Get decrypted data from dapp6 and use the data on the eapp6 to test program.

The original data is: 7 8 9 0. The encrypted data is: 6 7 4 5.

Here are my codes. The only one that can NOT be changed is the test file cpp.
