1. PROGRAMMING  LANGUAGE:

What is programming language?

A programming language is a formal language, which comprises a set of instructions that produce various kinds of output. Programming languages are used in computer programming to implement algorithms. Most programming languages consist of instructions for computers.

How many types of programming language?

Programming language are two types:

  • Low level Language :

    low level language is the language that computer can understand easily. It is machine depend ,required good knowledge on computer architecture.

    Low level language are also two types :

    • Machine level language or Binary language or 0 1 language :

      It is common language every computer can understand. It only understand
      0 1 format language, computer can understand easily.
      All machine level program written on
       .obj file    ⬇️ 
      0100111101010111
1001011011111001
1111001111011010
       called object file.
      1st gen language.

    • Assembly language :

      Assembly language is a low-level symbolic code language. Mnemonics are use 
      such as MOV , ADD , SUB , MUL , DIV having their unique code . It is easy to understand .Then, Mnemonics is converted into machine level language by the help of translator called assembler. Machine dependent.                                   2nd gen language.

  • High-level language :

    High level language is the language that programmer or users can understand easily. Easy to understand code and debug. The program is not directly executed by computer , always translator is required for execution. It machine independent. Example - c ,c++, java, python. 
Translators:Translators are the programs which convert low or high language to machine level lanuage
that computer can read easily.
The translators are mainly three types:
  1. Assembler
  2. Compiler
  3. Interpreter 

Assembler :

Assembler is translator. It converts low level language( Assemble language) to machine language.

Compiler :

Compiler is most popular and preferable translator. If whole code is correct then the program execute other wise it will show error on which line.

Interpreter :

Interpreter is also a translator. It checks statement step by step into machine language , it stops and shows error when one statement is incorrect. The program execute when whole statement check one by one until last statement comes.

2. About C Language :

C Language was developed by Dennis Ritchie in 1970 at Bell laboratories.

Syntax of C language :

Print name in a pattern | name as abbreviation | C-Program

Image
Write a c program to display the name in the following pattern. If the name is Rahul Das than it should display R.Das . Print abbreviation name: Tips:- Use character array to store stuff given by user. You need to use strlen function which is present in the string.h header file to find the length. Code:- #include<stdio.h> #include<string.h> //for strlen() funtion. void main() { char name[20]; int var=0,n=0; printf("Enter Your name :- "); gets(name); var=strlen(name); for(int i=0;i<=var;i++) { if(name[i]==' ') { n=i+1; } } printf("\nYour attribute is :- "); printf("%c.",name[0]); for(int j=n;j<var;j++) { printf("%c",name[j]); } printf("\n\n"); } Output:-
