#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

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-->
