Write a c++ program to implement the encryption and decryption functions for such a scheme that will split the original file into two new files and vice versa. one of these two new files will containt all the characters in the original file in odd position and the other will contain all characters in the even position. for example, if the original file contained the text: hello world! then the 1st file would contain : hlowrd and the 2nd file would contain: el ol!

1st function:

void split(char sourcefile[ ], char destfile1[ ], char dest file2[ ]);

function should:

i. open sourcefile as an input file stream

ii. open destfile2 and destfile2 as output file streams

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. the highest speed measured was 78.1 mbps. the complete list of 50 data speeds has a mean of x overbarequals16.11 mbps and a standard deviation of sequals18.65 mbps. a. what is the difference between carrier's highest data speed and the mean of all 50 data speeds? b. how many standard deviations is that [the difference found in part (a)]? c. convert the carrier's highest data speed to a z score. d. if we consider data speeds that convert to z scores between minus2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant? a. the difference is nothing mbps.
