1) (1.5 point each, 6 total) Suppose a file named "letters" contains the following characters: aabbccddeeffgghhiijjkkll a. What is the name of the file created by the function call unzip file("letters"); b. Write the contents of the file written by the function call unzip file("letters"); c. What is the name of the file created by the function call zip file("letters"); d. Write the contents of the file written by the function call zip file("letters") (2 points) Compute the bitwise XOR between 10010100 and 11191010. (2 points) Suppose you are looking at the byte at index byte_pos in the file you are encrypting in a call to encrypt_file. Assuming std::string password stores the password you are using to encrypt, write the line of code to get the respective character to XOR with the current byte. 2) 3)
