Concept explainers

Operations

In mathematics and computer science, an operation is an event that is carried out to satisfy a given task. Basic operations of a computer system are input, processing, output, storage, and control.

Basic Operators

An operator is a symbol that indicates an operation to be performed. We are familiar with operators in mathematics; operators used in computer programming are—in many ways—similar to mathematical operators.

Division Operator

We all learnt about division—and the division operator—in school. You probably know of both these symbols as representing division:

Modulus Operator

Modulus can be represented either as (mod or modulo) in computing operation. Modulus comes under arithmetic operations. Any number or variable which produces absolute value is modulus functionality. Magnitude of any function is totally changed by modulo operator as it changes even negative value to positive.

Operators

In the realm of programming, operators refer to the symbols that perform some function. They are tasked with instructing the compiler on the type of action that needs to be performed on the values passed as operands. Operators can be used in mathematical formulas and equations. In programming languages like Python, C, and Java, a variety of operators are defined.

Question

Write code in C.

Write a program that prompts the user to enter an integer n and computes 1 + 2 + 3 + ... + (n − 1) + n.
Validate the input to ensure that n is a positive integer (i.e. n > 0) and loop to re-prompt until a valid
value for n is entered. Reference lecture notes, HW 1 Question 1, and week 2 video on Blackboard for an
example validating user input. Once you validate n, calculate the sum using two different methods:
1. Use a loop to calculate the sum from 1 + 2 + ... + n
2. This nth partial sum of infinite series whose terms are natural numbers (Wikipedia URL) equals
n(n+1)
2
Display the resulting sums for both approaches as int. Why it is ok to display as int is asked as question to
answer in Section F. Finally, display a message if the approaches are equal or else they are not equal.

Use nested loop in Java language. This program asks the user to enter an integer from 3 to 9* and prints a pattern of numbers based on that number.* For example, given the number 4 as input, the output would be:* * 1** 21** 321** 4321** 321** 21** 1** * Print a newline between the prompt and the beginning of the stars.* Note that no input validation is required.
Write a program that plays a simple dice game between the computer and the user. When the program runs, a loop should repeat 5 times. Each iteration of the loop should do the following: Generate a random integer in the range of 1 through 6. This is the value of the computer’s die. Ask from user an integer in the range of 1 through 6. This is the value of the user’s die. The die with the highest value wins. (In case of a tie, there is no winner for that particular roll of the dice.) You need to validate the input if it’s correct or not. As the loop iterates, the program should keep count of the number of times the computer wins, and the number of times that the user wins. After the loop performs all of its iterations, the program should display who was the grand winner, the computer or the user.
Question 2: Write a program to read student ID and check whether it is odd/even number. Output a 4X4 badge if the student ID is even number and output a 3X3 badge if it is odd number. The badge is built up by the (height X width) of asterisks. (Use for-loop to draw the asterisks, do not hard-coded)

Write a program that reads in numbers from the user and outputs the information specified below. Part One: Get Valid Input Read in two integers from the user: a lower end of a range and an upper end of a range. Check if the numbers are valid (lower cannot be greater than upper). If the numbers are invalid, use a loop to ask for new numbers. Continue looping until you get two valid values. Part Two: Calculate the Sum Use a loop to calculate the sum of all values from lower (inclusive) to upper (inclusive). Output the sum to the user. Part Three: Analyze the Sum Determine if the sum is even or odd. Determine if the sum is positive, negative, or zero. Output this information to the user. Part Four: Calculate the Average Calculate the average of all numbers in the range from lower (inclusive) to upper (inclusive).

Write a program that uses loops to collect data and calculate the average score over a number of tests for a number of students. Use Small Basic for this assignment. The program should : 1. first ask the user to enter the number of students in the range of 1 to 10. 2. then the program asks the user to enter the number of tests (in the range of 1 to 5) 3. Then use a loop to collect the scores for those many tests for each student. The outer loop will iterate once for each student. The inner loop will iterate several times, once for each test. Each iteration of the inner loop will ask the user to enter the score for a test of a student. 3. After all iterations, the program should calculates and display the total scores and average score for each student.
Write a program that asks the user to enter how many students they have. Use a for loop to iterate through each student. For each student, allow the user to enter as many scores as they want and let them know that entering -1 will indicate the end of entering scores( note: use a while loop with sentinel value). Sum all the scores for each student and display the total on the screen . For example: Student 1 Total score is 340 Student 2 Total score is 200
