Write a program in python or c++ that has two functions:Function one is called: _encryptFunction Two is called: _decryptFunction one takes plain text ,and assesses the indexed value of each letter in the string. For example, a=1,b=2 . It then adds three to the indexed valus , and produces encrypted text , based off of the plain text. Function two reverse this. here is sample output:_encrypt(‘how do you do’)Unsecured: howdoyoudoSecured: lsahscsyhs_decrypt(‘lsahscsyhs’)Uns ecured: lsahscsyhsSecured: howdoyoudo

Develop the program incrementally: a) start by reading and displaying each line of the input file to make sure you are reading the data set correctly. b) use the split string method to extract information from each line into a list. print the list to prove that this step is working correctly. d) convert the exam scores to type int and calculate the student’s average. display those items to prove this step is working correctly. e) create a tuple containing the six items for each student (name, exam scores, exam mean). display the tuples to prove this step is working correctly. (optionally, you may want to have the exam scores in a list so your tuple is (name, scores_list, f) append each tuple to a list. display the list to prove this step is working correctly. g) use the sort list method to re-order the tuples in the list. display the list to prove this step is working correctly. h) use a for statement to display the contents of the list as a table (with appropriate formatting). i) use a for statement to calculate the average of all scores on exam #1, then display the results. note that you could have calculated this average within the first loop, but we are explicitly requiring you to do this calculation by looping though your list of tuples. j) add the logic to calculate the average of all scores on exam #2, then display the results.

3. write assignment statements that perform the following operations with the variables a, b, and c: a. adds 2 to a and assigns the result to b b. multiplies b times 4 and assigns the result to a c. divides a by 3.14 and assigns the result to b

Which of these is not a type of socket? aga (alternating grid array) pga (pin grid array) spga (staggered pin grid array) lga (land grid array)
