PREFACE TO THIS EDITION

Programming in C is being taught today as an important subject in

almost all the degree programmers. This manual has been used as a

text in ‘GEETA INSTITUTE OF ENGINEERING & TECHNOLOGY’. It has

been specially adapted as a training manual in Programming

technology laboratory. This manual for students and teachers is alike

because of its unique and distinctive learning methodology and

simple writing style. It suits to both beginners and experienced. This

manual covers all the aspects of basic programming concepts that are

needed by the engineers for implementation in various fields.

Basic descriptions of concepts is included to facilitate better

understanding and providing supplementary information and notes

that complement and stand apart from the general text that has been

included. At end of each description of experiment some questions

and space for writing the program is provided to test the basic

understanding of the same. Thanks to all the user students for their

positive criticism and attitude.

WELCOME TO THE C PROGRAMMING LAB

The laboratory work is a group activity where every individual

contributes to the thinking process and activities of the group. It is

always said that whatever you see you forget, what you read you

remember; whatever you’ll do you understand. Laboratory experiments

are integral part of the course. That makes the practical as an integral

part of learning process.

To make laboratory experiments effective, each student must obey

the following rules:

Attendance

Attendance is required at all labs without exception. There are no

make-up labs in this course. Performance will be judged based on the

experiments conducted, quality and punctual submission of the labs

reports for each experiment.

Faculty will take attendance. Failure to be present for an experiment

will result in loosing entire marks for the corresponding lab. However,

genuine cases may be considered for repeat lab. Student must not

attend a different lab groups/section from the one assigned at the

beginning of the class. If a student misses a lab session due to

unavoidable circumstances can provide a legitimate proof as soon as

possible, he/she may be then be allowed by the lab instructor, to make-

it-up.

Laboratory Report

At the end of every lab student will be assigned to write-up one of the

experiment’s problem. Your report must present a clear and accurate

account, results you obtained and what the results mean.

Note:

Before leaving the laboratory, each student must ask the lab

instructor for the experiment to be conducted on the next lab

turn, so that the student come prepared after reading and

reviewing the reallocated experiment. Faculty might check

student’s preparedness and understanding of the experiment.

Do not hesitate to clear any of your doubts concerning the

experiments.

Shut down your system after you have finished with your

experiment.

Instructions

1. Students will not be allowed after the scheduled time.

2. No student will leave the lab without permission.

3. Student should bring their lab manual & should understand it

thoroughly.

4. Any confusion may be clarified from the faculty before starting

the experiments.

5. Students have to maintain discipline and silence in the lab.

6. Students are to remain with their allotted work station.

7. Be attentive at all time.

INTRODUCTION TO C PROGRAMMING LAB

OBJECTIVE: C language came in to existence in 1972 as a high level language. It was developed by Dennis Ritchie at Bell Lab. It was strongly associated with UNIX. It is well suited for structured programming. It is a robust language with number of functions and operators to handle any complex program. C is highly portable. Structure of C Program A C program may consist of one or more following sections: Documentation Section: it gives the name of the program. Link Section: It provides instruction to the complier to link functions from the system library. For example: #include<stdio.h>

#include<conio.h> Definition section: - It is used to define or set values to variables. Global declaration section: - Global Variables are declared in this section. Every C program must have one main ( ) function. The program execution begins at the opening brace and ends at the closing brace of main function section. Subprogram section: - It contains all the user-defined functions that are called in the main function. Executing a program written in C language involves a series of steps:

1. Creating the program 2. Compiling the program 3. Linking the program with functions that are needed from C library 4. Executing the program

Common place holders used by printf and scanf functions are:

int uses %d

float uses %f

char uses %c

character strings use %s
