1. The encryption process can be a simple and straightforward task. One such encryption algorithm is as follows: For each line of text to encrypt For each character of the line to encrypt • determine the 8-bit binary ASCII value of the character flip all the bits in the ASCII value (0 becomes 1 and 1 becomes 0) convert the bit-flipped ASCII value to a hexadecimal representation print the hexadecimal value to standard output followed by a single space print a newline character to the screen. For example, the ASCII value of the character 'A' is 65, which is 0100 0001 in binary. Flipping the bits gives you 1011 1110, which is represented as 'be' in hexadecimal. Write a program to reverse the encryption process stated above. Input will be from a datafile. The first line contains a single integer, n, ndicating the number of lines of encrypted input to decrypt. For each encrypted input line, output the decrypted line properly labeled. Let the user input the file name from the keyboard. Refer to the ample output below. Sample File: : 37 9A 93 93 90 DF A8 90 8D 93 9B DE 36 DF 90 88 91 DF CD DF 9C 9E 8B 8C D1 Sample Run: Enter file name: decrypt.txt Line 1: Hello World! Line 2: I own 2 cats.

C++ please

1. The encryption process can be a simple and straightforward task. One such encryption algorithm is
as follows:
For each line of text to encrypt
For each character of the line to encrypt
• determine the 8-bit binary ASCII value of the character
flip all the bits in the ASCII value (0 becomes 1 and 1 becomes 0)
convert the bit-flipped ASCII value to a hexadecimal representation
print the hexadecimal value to standard output followed by a single
space
print a newline character to the screen.
For example, the ASCII value of the character 'A' is 65, which is 0100 0001 in binary. Flipping the bits
gives you 1011 1110, which is represented as 'be' in hexadecimal. Write a program to reverse the
encryption process stated above. Input will be from a datafile. The first line contains a single integer, n,
indicating the number of lines of encrypted input to decrypt. For each encrypted input line, output the
decrypted line properly labeled. Let the user input the file name from the keyboard. Refer to the
sample output below.
Sample File:
2
B7 9A 93 93 90 DF A8 90 8D 93 9B DE
B6 DF 90 88 91 DF CD DF 9C 9E 8B 8C D1
Sample Run:
Enter file name: decrypt.txt

Line 2: I own 2 cats.
