We have a program core consisting of five conditional branches. the program core will be executed thousands of times. below are the outcomes of each branch for one execution of the program core (t for taken, n for not taken) branch 1: t-t-t branch 2: n-n-n-n branch 3: t-n-t-n-t-n branch 4: t-t-t-n-t branch 5: t-t-n-t-t-n-t assume the behavior of each branch remains the same for each program core execution. for dynamic schemes, assume each branch has its own prediction buffer and each buffer is initialized to the same state before each execution. list the predictions for the following branch prediction schemes: a. always taken b. always not takern c. 1-bit predictor, initialized to predict taken d. 2-bit predictor, initialized to weakly predict taken what are the prediction accuracies?

Write a program to analyze student’s scores. each student’s id and 4 original test scores are saved in the attached file “student_id_scores.txt”. assume there are exactly 15 students in the class.• the program first opens the file, reads student’s ids and scores from the file and saves them in two arrays: o create a one-dimensional string array “ids” to store the student’s ids.o create a (parallel) two-dimensional int array “scores” to store student’s original test scores. this array has 5 columns, the original 4 test scores should be saved in the first 4 columns, and the last column will be used to save the average score after the calculation in next step.• the program then retrieves test scores from the array “scores”, calculates average score and determines the final letter grade based on the rules in the table below for each student. assume average score is integer value.average score = (score1 + score2 + score3 + score4) / 4average score letter grade90 ~ 100 a80 ~ 89 b70 ~ 79 c60 ~ 70 d0 ~ 60 f• the average score should be saved back in the 5th column of “scores” array.• create a new parallel one-dimensional char array “grades” to save each student’s letter grade.• program also needs to find the number of a, number of b, number of c, number of d and number of f grade. as well as the highest, lowest and average score of the class.• finally, program will display all of the original scores and all results on the computer screen using the format shown as the sample output below.• the program must contain at least the following functions: (1) a function “getscores” to read and store data into “ids” and “scores” arrays.(2) a function “analyzescores” to calculate student’s average score, determine letter grade, get the number of a, b, c, d and f, find the highest, lowest and average score of the class.(3) a function “displayresults” to display all of the results
