C programming | Fundamentals & Basic information

By Programming codester

 PROGRAMMING CODESTER 

 


  • In the previous tutorial we studied the basics of programming language and also learnt about flow chart and algorithm and about interpreter and compiler. 
  • So, we start with c programming in this tutorial. 
  • In the technical world many languages are available for talking to computers like c, c ++, java, java script, python, c#, and many more. 
  • But for beginners and those who are new to this stream c programming is very easy to learn and it's very useful to learn other languages also so we can also say that c language is the base of programming language. 
  •  C programming was created in the 1972s by Dennis Ritchie and remains very widely used and influential.  

In this tutorial we will study about: 

  • Fundamentals of c programming 
  • Application of c programming 
  • Structure of c programming 
  • First basic program “hello world”. 

Let's begin! 

Features of c language: - 

  1. Modularity 
  2. Extensibility 
  3. Elegant syntax 
  4. Case sensitive 
  5. Less memory required 
  6. The standard library concepts 
  7. The portability of the compiler 
  8. A powerful and varied range of operators  
  9. Ready access to the hardware when needed 

Application of c language: - 

  • Operating System. The C programming language was created with the intention of writing UNIX operating systems. ... 
  • 3D Movies. ... 
  • Intermediate Language. ... 
  • Play Important Role in Development of New Programming Language. ... 
  • Embedded Systems. 

Structure of c: - 

 

So, the structure of c is very easy to learn. First will be documentation part, second will be link section, third will be definition section, forth will be global variable declaration and then started main program with void main or int main function. 

So, let's write the first program of c which is Hello World. 

Write a program to print hello world in c. 

 

Output: - 

 

Practice question of this tutorial: 

  1. Who is the father of c programming? 
  2. Application of c. 
  3. Write a program to print your name based on example of hello world. (We will learn in detail in our next blog) 
  4. Why is c programming the base of any programming language? 
Today question:
What will be the output of the following code snippet?

#include <stdio.h>
void solve() {
    int first = 10, second = 20;
    int third = first + second;
    {
        int third = second - first;
        printf("%d ", third);
    }
    printf("%d", third);
}
int main() {
 solve();
 return 0;
}
Answer :10 30

So, in the next tutorial we will study printf and scanf function and their syntax, and primary and secondary data types of c language and basic programs. 

Stay tuned! 

Learn and explore.

C programming | Printf and scanf ||

By Programming codester
  Programming Codester   Printf and scanf function with C language:   We learnt fundamentals of C in previous tutorial.   If you haven't read the previous tutorial, I mentioned the link below here.   So now it's time to learn print and scanf function.   Both printf and scant functions are inbuilt library functions, defined in stdio.h (header file).   Printf ;   The printf functions create and output strings formatted at runtime . They are part of the standard C library. Additionally, the printf functionality is implemented in other languages (such as Perl). These functions allow a programmer to create a string based on a format string and a variable number of arguments.   In shot Printf function is used to print any statements in C language.   The syntax of printf function:   Printf (“any statement you want”);   Example syntax of pr intf :   Printf (“programming codester ”);    Scanf :   In ...

  Programming codester   C programming   Structure   on user’s demand I bring the tutorial of structure in c language!   So first find the error from this code: #include<stdio.h> void main() { printf("hello"); return 0; } If you want to see my other tutorial of c programming I will mention all link at the end of this tutorial. So, stay tuned!   So guys lets start structure with C!   If you want to learn structure, you have to knowledge of datatypes!   So, first we learn about datatypes.   DATATYPES:   There are 2 types of data type :   1.Primary datatype:   In this datatype float, int, char, void, etc. Are the best examples.   2. Secondary Data type:   In secondary data type there are 2 types of secondary data types!                     1] Derived Data type   ( Array , pointer)   2] User defined Dat...

Programming Codestrer   Importance of c programming   { embedded programming }   Q & A SESSION   So, hello my wonderful people!   In this tutorial I tried to cover basic and most asked question by students, beginners and programmers.   -----------------------------------------------------------------------------------------------------------   1.Whenever students start coding, there is always a question in the mind of students which language should be first?   -> So, my answer is you should start with c programming because c programming is a very basic and easy language to learn coding and programming.   -----------------------------------------------------------------------------------------------------------   2. Why C is the base of programming language?   -> The C language is a high-level, general-purpose programming language. It provides a straightforward, consistent, powerful interface for programming systems ...

C++ || Operators with c++

By Programming codester
  Programming codester   Operators with c++ :     In the previous tutorial we learnt about arithmetic and assignment operator with c++ .   Now let' s learn other operators!   We already know there are six types of operators!      Now let's learn about Logical operator, Bitwise operator, Relational operator , and other opera tors .   1.logical operators:   Logical operators are used to check whether an expression is true or false . If the expression is true , it returns 1 whereas if the expression is false , it returns 0 .   Operator   Example   Meaning   &&   expression1 && expression2   Logical AND.   True only if all the operands are true.   ||   expression1 || expression2   Logical OR.   True if at least one of the operands is true.   !   ! expressio n   Logical NOT.   True only if the operand is false.   In C++, logical operat...

  PROGRAMMING CODESTER   What is compiler and interpreter?   Hello wonderful people!   So, in our previous blog we learnt about flow charts and algorithms .   So now we will be studying types of computer languages and also learning what compiler and interpreter.   Types of computer languages:   Machine level language OR Low-level language   It is the language of 0’s and 1’s.   Computers directly understand this language.   Assembly language   It uses short descriptive words (MNEMONIC) to represent each of the machine language   instructions.   It requires a translator knows as assembler to convert assembly language into machine language   so that it can be understood by the computer.   Examples: 8085 Instruction set   Higher level language   It is a machine independent language.   We can write programs in English like manner and therefore easier to learn and use.   Examples: C, C++, JAV...

By Programming codester
Programming codester   Object oriented programming with c++   Operators and variables with c++   In the previous tutorial, we learnt about data types and user input cin .   Question of c programming What is the out of following program? #include <stdio.h> int main ( ) { int i = 10 ; int * p = & i ; printf ( "%d \n " , * p ++ ) ; } AANSWER:10 Now we start a new tutorial!   We will learn about different operators in c++ ( oop )   Variables:   Variables are containers to store any data.   i.e., to store any biscuits, we use boxes.   for example, int is used for integers, float is used for floating numbers, char is used for any character.   So variable is the container who stores our values and data.   Variable scope:   Local variable: are declared inside the braces of any function and can be accessed from there.   Global variable: are declared outside any function and...
