2. C
• C is the successor of B(BASIC) and A(ALGOL)
languages.
• Most Popular language for over 3 decades
(30+ years)
• C is a Procedure oriented programming
language
– i.e. data should be assign first like
– Data then function.
3. Why we have to learn C?
1. To better understand other languages.
- Like:- c++, c# and java.
2. To understand how data flow with in the
compiler.
3. To development of coding logic.
4. Software are used to run c language
code.
• Turbo c or turbo c++
• Auto C
• Borland C
• These software run .c extension files which tell the compiler or interpreter
that .c file is a file that belongs to c language
• Like for c++ its .cpp
• For java its .java
• For c# its .cs extension files.
5. Lets understand C by a simple Code.
#include<stdio.h> or #include”stdio.h”
#include<conio.h> or #include”conio.h”
Void main()
{
printf(“Hello world”);
}
Output: Hello world
Note:
#include is preprocessor which tell compiler to search the directory(library files)
within <stdio.h>, “conio.h” Here stdio.h is a library file which contain printf()
function.
