Programming & Computer Science Answers

1. What do you mean by Program? Briefly describe the basic structure of C programs.

2. What is a token? Differentiate between a for loop and a while loop? What are it uses?

3. What is a data type? Differentiate between array and pointer. Write a program to interchange 2 variables without using the third one.

4. What is an array of pointers? Is it possible to have negative index in an array? Why is it necessary to give the size of an array in an array declaration?

5. Submit a Report "the impact of improving debugging skill on programming ability"

Write a C++ program called Winner.cpp for the hackathon competition, the program must do the following: 1.1 Declare all necessary variable and constants. 1.2 Declare a parallel array named candidate and initialize it using the information given above. 1.3 Declare four parallel arrays named judge1Score, judge2Score, percScore, totalScore and initialize them using default values as indicated above. 1.4 Populate the judge 1 score array with random numbers from 1 to 100. 1.5 Populate the judge 2 score array by allowing the user to enter the judge’s score . 1.6 Calculate the total score per candidate and store the results in the correct array. 1.7 Calculate the total for all the candidates’ scores. 1.8 Calculate the percentage for all votes for each candidate and store the results in the correct array. 1.9 Display the competition details . 1.2. 1.10Determine the candidate with highest percentage and display the candidate as well as the highest percentage

Third year programming students have entered a hackathon competition and they are judged by two judges who gives them a score from 1 to 100. You are required to write a program that will help the organizers to tally their scores as well as to determine who the winner is.

Given an array arr[] sorted in ascending order of size N and an integer K.

Check if K is present in the array or not. (Use Binary Search)

Input: N = 5

K = 6

arr[] = {1,2,3,4,6}

Output: 1

Explanation: Since, 6 is present in the array at index 4 (0-based indexing),

output is 1

We've already tried comparing 3 numbers to see the largest among all, so let's try a more complicated mission where we locate the position of the largest among 5 numbers. There are only 4 possible cases for this mission:

- if the largest digit is the first digit, print "Leftmost"

- if the largest digit is the third digit, print "Middle"

- if the largest digit is the last digit, print "Rightmost"

- if none of the above is correct, print "Unknown"

Now, show me how far you've understood your lessons!

Input

A line containing a five-digit integer.

1·4·6·3·2

Output

A line containing a string.

Middle

• Create your own example of each possibility in Python code. List the code for each example, along with sample output from trying to run it.

Write two procedure called mean_(int N) and var_(int N) that calculate and display the mean and variance of N real entered from the keyboard (without using an array).
