C PROGRAMMING LANGUAGE(introduction)

 What is c?

Dennis Ritchie created the potent and extensively used general-purpose programming language C at Bell Laboratories in the early 1970s. Although it was initially intended for system programming, it has now been applied to a wide range of tasks, such as creating games, operating systems, embedded systems, and more software. C is a well-known language that can be used to construct both high-level and low-level software because of its efficiency, flexibility, and low-level capabilities.

Key features of C:

Procedural Language: C programs are structured as collections of functions or processes, in accordance with the procedural programming paradigm.

Portability: C programs are very portable because they can be compiled and executed with little to no modification on a variety of systems.

Efficiency: C is an efficient language to design programs that require high performance because it provides precise control over memory management and system resources.

Structured Programming: C allows programmers to generate structured, maintainable code by supporting elements like loops, conditionals, and functions.

Static Typing: C is statically typed, which means that variables are identified during compilation, assisting in the early detection of problems.

Rich Standard Library: The input/output, string manipulation, memory allocation, and other functions found in C's rich standard library are only a few examples.

Pointer Support: Direct memory manipulation and effective data access are made possible by C's support for pointers, which are variables that hold memory addresses.

HELLO WORLD PROGRAM:

The "Hello, World!" program, which merely writes the phrase "Hello, World!" to the screen, is a quintessential illustration of a C program. This is how it appears in C:

#include <stdio.h>

int main() {

    printf("Hello, World!\n");

    return 0;

}

HOW TO RUN A C PROGRAM:

A C compiler must be installed on your computer in order to run a C program. Microsoft Visual C++, Clang, and GCC (GNU Compiler Collection) are a few popular C compilers. Once you've written your C code in a text editor, use the relevant compiler command to compile it:

For instance, to use GCC to compile the "hello.c" program:

gcc -o hello hello.c

An executable file with the name "hello" will be produced by this command. The executable can then be used:

./hello

And this is what you ought to see:

Hello, World!

Conclusion:

C is a widely used, basic programming language with a long history. Understanding computer architecture, memory management, and low-level programming ideas are essential for developing software in a variety of fields, and learning C gives you a solid foundation in these areas.
