18CPL17/27 C PROGRAMMING LABORATORY BY SUNAGAR

Laboratory Programs:

1. Familiarization with computer hardware and programming environment, concept of naming the program files, storing, compilation, execution and debugging, taking any simple C- code.

PART A

2. Develop a program to solve simple computational problems using arithmetic expressions and use of each operator leading to simulation of a commercial calculator. (NO built-in math function)

3. Develop a program to compute the roots of a quadratic equation by accepting the coefficients. Print appropriate messages.

4. Develop a program to find the reverse of a positive integer and check for palindrome or not. Display appropriate messages.

5. An electricity board charges the following rates for the use of electricity: for the first 200 units 80 paise per unit: for the next units 90 paise per unit: beyond 300 units Rs I perunit. All users are charged a minimum of Rs. 100 as meter charge. If the total amount is more than Rs 400, then an additional surcharge of 15% oftotal amount is charged. Write a program to read the name of the user, number of units consumed and print out the charges.

6. Introduce I D Array manipulation and implement Binary search.

7. Implement using functions to check whether the given number is prime and display appropriate messages. (No built-in math function)

PART B

8. Develop a program to introduce 2D Array manipulation and implement Matrix multiplication and ensure the rules of multiplication are checked.

9. Develop a Program to compute Sin(x) using Taylor series approximation. Compare your result with the built- in Library function. Print both the results with appropriate messages.

10. Write functions to implement string operations such as compare, concatenate, string length. Convince the parameter passing techniques.

11. Develop a program to sort the given set of N numbers using Bubble sort.

12.Develop a program to find the square root of a given number N and execute for all possible inputs with appropriate messages. Note: Don't use library function sqrt(n).

13.Implement structures to read, write and compute average- marks and the students scoring above and below the average marks for a class of N students.
