A function is a group of statements that together perform a task. Every C program has at least one function, which is main(), and all the most trivial programs can define additional functions. You can divide up your code into separate functions.

C is mother language of all programming language.
It is a system programming language. It is a procedure-oriented programming language. It is also called mid-level programming language.
C evolved from a language called B, written by Ken Thompson at Bell Labs in 1970. Ken used B to write one of the first implementations of UNIX. B in turn was a descendant of the language BCPL (developed at Cambridge (UK) in 1967), with most of its instructions removed.
So many instructions were removed in going from BCPL to B, that Dennis Ritchie of Bell Labs put some back in (in 1972), and called the language C.
The famous book The C Programming Language was written by Kernighan and Ritchie in 1978, and was the definitive reference book on C for almost a decade.
The original C was still too limiting, and not standardized, and so in 1983, an ANSI committee was established to formalize the language definition.
It has taken until now (ten years later) for the ANSI ( American National Standard Institute) standard to become well accepted and almost universally supported by compilers.

A computer is an electronic device used to process data, converting the data into information that is useful to people.
A computer is a system made of two major components:
hardware and software.
The hardware is the physical equipment.
The software is the collection of programs (instruction) that allow the hardware to do the job.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

5. C programming language was developed in
1972 by Dennis Ritchie at bell laboratories of
AT&T(American Telephone & Telegraph),
located in U.S.A.
It was developed to be used in UNIX
Operating system.
It inherits many features of previous
languages such as B and BPCL.

7. C is mother language of all programming
language.
It is system programming language.
It is procedure-oriented programming
language.
It is also called mid level programming
language.
8. There are many features of c language are given below.
1) Simple
2) Machine Independent or Portable
3) Mid-level programming language
4) structured programming language
5) Rich Library
6) Memory Management
7) Fast Speed
8) Pointers
9) Recursion
10) Extensible
9. A sample C Program
#include<stdio.h>
int main()
{
--other statements
// Comments after double slash
}

10. Type a program
Save it
Compile the program – This will generate an
exe file (executable)
Run the program (Actually the exe created out
of compilation will run and not the .c file)
In different compiler we have different option
for compiling and running. We give only the
concepts.

11. #include <stdio.h> includes the standard input
output library functions.
The printf() function is defined in stdio.h .
#include <conio.h> includes the console input
output library functions.
The getch() function is defined in conio.h file.
void main() The main() function is the entry point
of every program in c language.
The void keyword specifies that it returns no value.
printf() The printf() function is used to print data on
the console.
getch() The getch() function asks for a single
character. Until you press any key, it blocks the screen.
12. The files that are specified in the include section
is called as header file
These are precompiled files that has some
functions defined in them
We can call those functions in our program by
supplying parameters
Header file is given an extension .h
C Source file is given an extension .c
13. This is the entry point of a program
When a file is executed, the start point is the
main function
From main function the flow goes as per the
programmers choice.
There may or may not be other functions
written by user in a program
Main function is compulsory for any C program
14. #include <stdio.h> includes the standard input
output library functions. The printf() function is defined
in stdio.h .
#include <conio.h> includes the console input
output library functions. The getch() function is defined
in conio.h file.
void main() The main() function is the entry point
of every program in c language. The void keyword
specifies that it returns no value.
printf() The printf() function is used to print data on
the console.
getch() The getch() function asks for a single
character. Until you press any key, it blocks the screen.
17. There are two input output function of c
language.
1) First is printf()
2) Second is scanf()
18. printf() function is used for output.
It prints the given statement to the console.
Syntax of printf() is given below:
printf(“format string”,arguments_list);
Format string can be
%d (integer),
%c (character),
%s (string),
%f (float) etc.
12/11/2015Session-1/Dr.M.karthika 18
19. scanf() Function: is used for input. It reads
the input data from console.
scanf(“format string”,argument_list);
20. Input
› scanf(“%d”,&a);
› Gets an integer value from the user and stores it
under the name “a”
Output
› printf(“%d”,a);
› Prints the value present in variable a on the
screen
Friday, December 11, 2015 20
21. Single line comment
› // (double slash)
› Termination of comment is by pressing enter key
Multi line comment
/*….
…….*/
This can span over to multiple lines

Escape Sequences
23. /* Testing the escape sequences */
#include <stdio.h>
int main(void)
{
printf("Testing the escape sequences:n");
printf("-----------------------------n");
/* 3 times audible tone */
printf("The audible bell ---> a aaan");
printf("The backspace ---> b___ bTestingn");
/* printer must be attached...*/
printf("The formfeed, printer ---> f fTestn");
printf("The newline ---> n nn");
printf("The carriage return ---> r rTestingrn");

Format specifiers
%d is the format specifier. This informs to the compiler that the incoming value is an integer value.
Other data types can be specified as follows:
%c – character
%f – float
%lf – double
%s – character array (string)
Printf and scanf are defined under the header file stdio.h
