What is Program and Programming language?



It is a set of instructions to complete the task. instruction can be mathematical, logical, conditional, and comparison based.
PSEUDO CODE of addition program
a=10
b=20
c=a+b,
display c
Programming language:-
It is a set of codes to create a program practically and load into a compiler or interpreter.
Software is a set of programs and programs will be developed by a set of codes hence programming language is used to develop a software application.
Type of Programming languages:-
1 Based on Execution:-
1.1.1 low level:-  It will be executed directly under the operating system with no need to use any intermediate.
Binary Code
1.1.2  middle level:-  It will be executed by Single Intermediate means compiler or interpreter to convert program code into machine code.
C, CPP, HTML, Assembly code
1.1.3  high level:-  It will be executed by a minimum of Two Intermediate means multiple compiler and interpreter.
Java,.NET, Objective-c, Kotlin, C#, VB,, Python, PHP these all are programming language is the part of high level.
2  Based on Structure
2.1 Structured:-  This type of programming language syntax structure and program flow is pre-define .program will be started by top to bottom or bottom to top approach.
C, CPP,JAVA,PYTHON,PHP
Procedure, Function, Class
2.2 Unstructured:-  This type of programming languages has no proper structure, it can be executed from any position.
COBOL, PASCAL, FORTON, PYTHON, PHP
Without any procedure, function, class

    a=10
    b=20
    print("before swap")
    print(a,b)
    temp=a
    a=b
    b=temp
    print("after swap")
    print(a,b)

    WAP to swap two numbers without using a third variable
    a = 5
    b =9

    a,b=b,a

    print(a,b)

    #convert temperature from Celsius to Fahrenheit?
    # formula --> fahrenheit = (celsius * 1.8) + 32

    celsius=float(input(" Temperature in Celsius : "))
    fahrenheit=(celsius*1.8)+32
    print("{0} degree Celsius is equal to {1} degree Fahrenheit".format (celsius,fahrenheit))

    Fahrenheit= 54.
    Celsius = ((Fahrenheit-32)*5)/9.
    print("Temperature in Celsius is: ");
    print(Celsius);

    COLOUR=("BLUE","RED")
    #COLOUR=("GREEN")
    print(COLOUR[0],COLOUR[1])


    a=12345
    b=23.56
    c="hello"

DSA in C# | Data Structure and Algorithm using C#

  DSA in C# |  Data Structure and Algorithm using C#: Lecture 1: Introduction to Data Structures and Algorithms (1 Hour) 1.1 What are Data Structures? Data Structures are ways to store and organize data so it can be used efficiently. Think of data structures as containers that hold data in a specific format. Types of Data Structures: Primitive Data Structures : These are basic structures built into the language. Example: int , float , char , bool in C#. Example : csharp int age = 25;  // 'age' stores an integer value. bool isStudent = true;  // 'isStudent' stores a boolean value. Non-Primitive Data Structures : These are more complex and are built using primitive types. They are divided into: Linear : Arrays, Lists, Queues, Stacks (data is arranged in a sequence). Non-Linear : Trees, Graphs (data is connected in more complex ways). Example : // Array is a simple linear data structure int[] number...

JSP Page design using Internal CSS

  JSP is used to design the user interface of an application, CSS is used to provide set of properties. Jsp provide proper page template to create user interface of dynamic web application. We can write CSS using three different ways 1)  inline CSS:-   we will write CSS tag under HTML elements <div style="width:200px; height:100px; background-color:green;"></div> 2)  Internal CSS:-  we will write CSS under <style> block. <style type="text/css"> #abc { width:200px;  height:100px;  background-color:green; } </style> <div id="abc"></div> 3) External CSS:-  we will write CSS to create a separate file and link it into HTML Web pages. create a separate file and named it style.css #abc { width:200px;  height:100px;  background-color:green; } go into Jsp page and link style.css <link href="style.css"  type="text/css" rel="stylesheet"   /> <div id="abc"> </div> Exam...

Conditional Statement in Python

It is used to solve condition-based problems using if and else block-level statement. it provides a separate block for  if statement, else statement, and elif statement . elif statement is similar to elseif statement of C, C++ and Java languages. Type of Conditional Statement:- 1) Simple if:- We can write a single if statement also in python, it will execute when the condition is true. for example, One real-world problem is here?? we want to display the salary of employees when the salary will be above 10000 otherwise not displayed. Syntax:- if(condition):    statements The solution to the above problem sal = int(input("Enter salary")) if sal>10000:     print("Salary is "+str(sal)) Q)  WAP to increase the salary of employees from 500 if entered salary will be less than 10000 otherwise the same salaries will be displayed. Solution:- x = int(input("enter salary")) if x<10000:     x=x+500 print(x)   Q) WAP to display th...
