String Assignment Questions based on Programming

Operators Assignment Questions

Q1: (Convert Celsius to Fahrenheit) Write a program that reads a Celsius degree in a double value from the console, then converts it to Fahrenheit and displays the result. The formula for the conversion is as follows: fahrenheit = (9 / 5) * celsius + 32 Q2: (Compute the volume of a cylinder) Write a program that reads in the radius and length of a cylinder and computes the area and volume using the following formulas: area = radius * radius * pi volume = area * length

Q3. (Financial application: calculate tips) Write a program that reads the subtotal and the gratuity rate, then computes the gratuity and total. For example, if the user enters 10 for subtotal and 15% for gratuity rate, the program displays $1.5 as gratuity and $11.5 as total.

Q4. (Sum the digits in an integer) Write a program that reads an integer between 0 and 1000 and adds all the digits in the integer. For example, if an integer is 932, the sum of all its digits is 14. Hint: Use the % operator to extract digits, and use the / operator to remove the extracted digit. For instance, 932 % 10 = 2 and 932 / 10 = 93

Q5. (Find the number of years) Write a program that prompts the user to enter the minutes (e.g., 1 billion), and displays the number of years and days for the minutes. For simplicity, assume a year has 365 days.

Q6: (Health application: computing BMI) Body Mass Index (BMI) is a measure of health on weight. It can be calculated by taking your weight in kilograms and dividing by the square of your height in meters. Write a program that prompts the user to enter a weight in pounds and height in inches and displays the BMI. Note that one pound is 0.45359237 kilograms and one inch is 0.0254 meters.

Q7. (Geometry: distance of two points) Write a program that prompts the user to enter two points (x1, y1) and (x2, y2) and displays their distance between them.

Q8: (Print a table) Write a program that displays the following table. Cast floatingpoint numbers into integers. a b pow(a, b) 1 2 1 2 3 8 3 4 81 4 5 1024 5 6 15625s

Control Statements Assignment 1

1. Write a program to find sum of two numbers?
2. Write a program to find given number is odd or even?
3. Write a java program to swap two variables?
4. Write a program to Swap two numbers without using third variable?
5. Write a program to check the given number is prime or not?

Control Statements Assignment 2 (Programs 2a, 2b,...)

1. Write a program to find factorial? Description: Factorial of any number is the product of an integer and all the integers below it for example factorial of 4 is 4! = 4 * 3 * 2 * 1 = 24.

2. Write a program to reverse number? Description : Reverse number means reverse the position of all digits of any number. For example reverse of 839 is 938. Hint: For this program you need modulus operator concept and while loop, while loop is used for check condition and modulus used for find the remainder.

3. Write a program to print Fibonacci Series? Description : Fibonacci series is in the form of 0, 1, 1, 2, 3, 5, 8, 13, 21,...... Hint: To find this series we add two previous terms/digits and get next term/number

4.Write a program to check given number is Armstrong number or not? Description: Armstrong number is a number that is the sum of its own digits each raised to the power of the number of digits is equal to the number itself. For example:  Three Digits Armstrong number is 153, 1 ^ 3 + 5 ^ 3 + 3 ^ 3 = 153  Four Digits Armstrong number is 1634, 1 ^ 4 + 6 ^ 4 + 3 ^ 4 + 4 ^ 4 + = 1634

5. Write a program to Find Largest Number Among Three Numbers Input three number from user and compare these number with each others and find largest number among these three numbers.

Control Statements Assignment 3 (Programs 3a, 3b ,....)

1. Find largest number among three numbers using ternary operator?

2. Write a program to check the given number is palindrome or not? Descritpion : A Palindrome number is a number that remains the same when its digits are reversed. Like 16461, for example: we take 121 and reverse it, after revers it is same as original number.
