objectives:
To provide
basic principles C programming language. To provide design & develop of C
programming skills. To provide practical exposures like designing flowcharts,
algorithms, how to debug programs etc.
Descriptions
(if any):
Demonstration
of Personal Computer and its Accessories: Demonstration and Explanation on
Disassembly and Assembly of a Personal Computer by the facultyincharge.
Students have to prepare a writeup on the same and include it in the Lab
record and evaluated.
Laboratory
Session1: Writeup on Functional block diagram of Computer, CPU, Buses, Mother
Board, Chip sets, Operating System & types of OS, Basics of Networking
& Topology and NIC.
Laboratory
Session2: Writeup on RAM, SDRAM, FLASH
memory, Hard disks, Optical media, CDROM/R/RW, DVDs, Flash drives, Keyboard,
Mouse, Printers and Plotters. Introduction to flowchart, algorithm and pseudo
code.
Note: These TWO Laboratory
sessions are used to fill the gap between theory classes and practical
sessions. Both sessions are to be evaluated as lab experiments.
Laboratory Experiments:
Implement
the following programs with WINDOWS / LINUX platform using appropriate C
compiler.
1. Design
and develop a flowchart or an algorithm that takes three coefficients (a, b,
and c) of a Quadratic equation (ax2+bx+c=0) as input and compute all possible
roots. Implement a C program for the developed flowchart/algorithm and execute
the same to output the possible roots for a given set of coefficients with
appropriate messages.
2. Design
and develop an algorithm to find the reverse of an integer number NUM and check
whether it is PALINDROME or NOT. Implement a C program for the developed
algorithm that takes an integer number as input and output the reverse of the
same with suitable messages. Ex: Num: 2014, Reverse: 4102, Not a Palindrome
3.
3a. Design
and develop a flowchart to find the square root of a given number N. Implement
a C program for the same and execute for all possible inputs with appropriate
messages. Note: Don’t use library function sqrt(n).
3b. Design
and develop a C program to read a year as an input and find whether it is leap
year or not. Also consider end of the centuries.
4. Design
and develop an algorithm to evaluate polynomial f(x) = a4x4 + a3x3 + a2x2 + a1x + a0, for a given value of x and
its coefficients using Horner’s method. Implement a C program for the same and
execute the program with different set of values of coefficients and x.
5. Draw the
flowchart and Write a C Program to compute
Sin(x) using Taylor series approximation given by Sin(x) = x  (x3/3!) + (x5/5!)  (x7/7!) +
……. Compare your result with the built in Library function. Print both the
results with appropriate messages.
6. Develop
an algorithm, implement and execute a C program that reads N integer numbers
and arrange them in ascending order using Bubble Sort.
7. Develop,
implement and execute a C program that reads two matrices A (m x n ) and B (p x
q ) and Compute product of matrices A and B.
Read matrix A and matrix B in row major order and in column major order
respectively. Print both the input matrices and resultant matrix with suitable
headings and output should be in matrix format only. Program must check the
compatibility of orders of the matrices for multiplication. Report appropriate
message in case of incompatibility.
8. Develop,
implement and execute a C program to search a Name in a list of names using
Binary searching Technique.
9. Write and
execute a C program that
i.Implements string copy operation
STRCOPY(str1,str2) that copies a string
str1 to another string str2
without using library function.
ii.Read a sentence and
print frequency of vowels and total count of consonants.
10.
a. Design
and develop a C function RightShift(x ,n) that takes two integers x and n as
input and returns value of the integer x rotated to the right by n positions.
Assume the integers are unsigned. Write a C program that invokes this function
with different values for x and n and tabulate the results with suitable
headings.
b. Design
and develop a C function isprime(num) that accepts an integer argument and
returns 1 if the argument is prime, a 0 otherwise. Write a C program that
invokes this function to generate prime numbers between the given range.
11. Draw the
flowchart and write a recursive C function to find the factorial of a number,
n!, defined by fact(n)=1, if n=0. Otherwise fact(n)=n*fact(n1). Using this function, write a C program to
compute the binomial coefficient nCr. Tabulate the results for different values
of n and r with suitable messages.
12. Given
two university information files “studentname.txt” and “usn.txt” that contains
students Name and USN respectively. Write a C program to create a new file
called “output.txt” and copy the content of files “studentname.txt” and “usn.txt” into output
file in the sequence shown below . Display the contents of output file
“output.txt” on to the screen.
STUDENT NAME

USN

NAME 1

USN 1

NAME 2

USN 2

13. Write a
C program to maintain a record of n student details using an array of
structures with four fields (Roll number, Name, Marks, and Grade). Assume
appropriate data type for each field. Print the marks of the student, given the
student name as input.
14. Write a
C program using pointers to compute the sum, mean and standard deviation of all
elements stored in an array of n real numbers.
Course
outcomes:
• Gaining
Knowledge on various parts of a computer.
• Able to
draw flowcharts and write algorithms
• Able
design and development of C problem solving skills.
• Able

Conduction
of Practical Examination:
1 . All
laboratory experiments ( nos ) are to be included for practical
examination. 2 . Students are allowed to
pick one experiment from the lot. 3 . Strictly follow the instructions as
printed on the cover page of answer
script for breakup of marks 4 . Change of experiment is allowed only once and
15% Marks allotted to the procedure part to be made zero.
