Answer 6

1. Write a program which asks for a number input from the keyboard. Add 40 to the number and then divide it by 5. Now, take modulus of that number with 2 and then multiply the resultant value by 10. Display the result.

2. Write a program which takes temperature in Celsius as input and then display the values after converting it to Kelvin and Fahrenheit.

3. Write a program to find all roots of a quadratic equation using if else. Take co-efficient of the quadratic equation as user input. Check for negative, positive or zero discriminant and calculate roots accordingly.

4. Write a program which asks user to input percentage and then it should display the grade using

following criteria. Use switch statement.

Percentage >= 95%

Grade A+

Percentage >= 90%

Grade A

Percentage >= 85%

Grade B+

Percentage >= 80%

Grade B

Percentage >= 70%

Percentage >= 60%

Grade C+

Percentage >= 40%

Grade C

Grade D

Percentage < 40%

Grade F

5. Write a program which takes two integer values as user inputs and prints their LCM and HCF

6. Write a program which takes integer value as user input and converts it to binary and octal system and then display the answers.

7. Write a program which takes an integer value as user input and prints its reverse.

8. Write a program which checks whether an input integer is prime number or not.

9. Write a program which asks for length and width of a rectangle and calculates the area and perimeter.

10. Write a program which takes length in meters as input and convert it to feet and inches and display it as output.
