Basic Structure explanation of c , c++ , html , python with the help of code

 

1. Basic structure of c program -

#include<stdio.h>

// #include<conio.h>

int main(){

int a ,b,c; // defining integer here 

// simple hello world 

printf("hello world");

// use of integer 

printf("Enter the value of a -\n"); // printf is use for print any value , sentense etc

scanf("%d",&a); // scanf is use for getting integer value 

printf("Enter the value of b -\n");

scanf("%d",&b);

c = a+b; //we can use any operater here

printf("%d",c );

getch();

return(0);

}

output -

hello world

enter the value of a =

12

enter the value of b =

12

value of c =24

2. basic structure of c++ program -

#include <iostream> // here we explaining header which include the explanation

using namespace std;
int main()
{
int a, b, c; //declaring integer
cout << "enter the value of a =" << endl; // use for print on output screen
cin >> a; // use for getting the value
cout << "enter the value of b =" << endl;
cin >> b;
c = a + b; // here we use any operator and the value of result goes in c
cout << "value of c =" << c; // print the value of c

return 0;
}

output -

enter the value of a =

12

enter the value of b =

12

value of c =24

3. basic structure of html -

<!-- HTML code -->

<!DOCTYPE html> <!-- This is explaining browser that it a document type-->
<html lang="en"> <!-- here we explaining language-->
<head>
<!-- meta is not important for us as starting of html learning -->
<meta charset="UTF-8">

<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title> <!--IT is a title of the website which you show in tab-->
<!-- we enter style tag here also -->
<style>
/* all css was we write here */
</style>
</head>
<body>
<!-- here we first use heading tag -->
<h1>this is a heading tag and the line was look on browser very bold , stronge and cool </h1>
<!-- here we use paragarph tag -->
