1. a. Convert degrees into Fahrenheit and vice versa

b. Calculate the salary of an employee given his basic pay, HRA = 10% of basic pay,

TA=5% of his basic pay and deductions IT = 2.5% of his basic pay

2. a. Check whether the given number is perfect number

positive divisors, that is, the sum of its positive divisors excluding the number

itself.

Example - The first perfect number is 6, because 1, 2, and 3 are its proper positive

divisors, and 1 + 2 + 3 = 6.

b. Solve quadratic equations for the given values of a,b,c.

3  a. Generate all Amstrong numbers upto n.

Defn: An Armstrong number of three digits is an integer such that the sum of the

cubes of its digits is equal to the number itself.

Example - 371 is an Armstrong number, since 3**3 + 7**3 + 1**3 = 371

b. Convert a decimal number to a hexadecimal number

4. a. Write a menu driven C program to

a. Insert an element into an array

b. Delete an element from the array (first occurrence)

5. a. Write a Menu Driven C Program to

a. Accept a string from the user

b. Encode the string.

c. Decode the string

Apply the following procedure to encode it.

1. Convert each character in a string to its ASCI value.

2. Add an integer value to it and display the encoded string

3. Decode the string using reverse procedure and display.

6. Write a C program to multiply two matrices that satisfy the constraint of matrix

Multiplication

7. Write a C program to find the saddle point of a matrix.

Defn: Given a RxC Matrix, A, i.e. R rows and C columns we define a Saddle-Point

as Saddle_Pt (A) for a row I and column j is that A(i,j) that is the minimum of Row 

i and the maximum of Col j.

8. Write a C program to implement a magic square of size n.

Defn: A magic square is an arrangement of numbers (usually integers) in a square

grid, where the numbers in each row, and in each column, and the numbers that run

diagonally in both directions, all add up to the same number.

9. Write a Menu driven C program to

a. Accept two numbers n and m

b. Sum of all integers ranging from n to m

c. Sum of all odd integers ranging from n to m

d. Sum of all even integers ranging from n to m

Display an error message if n > m. Create functions for each of the options

10. Write a Menu Driven C Program to implement the following using recursion

a. Factorial of a number

b. Fibonacci series

11. Create a structure Complex Number having real and imaginary part as properties.

Write functions to add and subtract the two complex numbers.

12. Define a structure called student having the properties of student_id, student name

and   branch of the student with a sub structure of marks of 3 subjects. Write a

Menu Driven   C Program to

a. Add new student detail

b. Delete a student detail

c. Display all student details

d. Display the average marks scored by the students

13. a. Write a C Program to remove all white spaces and newline characters from a

file.

b. Find whether a given word exists in the file. If it exists display the location of the

word

14. Write a C program to copy one file content to another file without using inbuilt

functions
