UNIT I & II
16 or 8 marks
1. Write the use of looping? Explain about the loops available in ‘C’ with appropriate C
programs.
2. Write a C Program to print all the calculator operations using switch statements.
3. Define an array? List the various types of arrays, Elaborate on Two-Dimensional
array with an example.
4. Write a program to sort the numbers stored in an array in descending order using
function. Pass the array as argument to a sort function.
5. Write a C Program to execute the payroll application with the data given using
Structure.
HRA = 18% of basic pay, DA = 15% of basic pay, PF = 10% of
basic pay, LIC = 7% of basic pay, Exclusion = PF LIC,
Total Salary = Basic Pay+HRA+DA+PF+LIC
Net Salary = Total Salary - Subtraction.

variable).
8. Implement a recursive function to compute the sum of the digits of a number.
9. Write a C program to create a union that stores different data types and demonstrate
how to access the data.
