Top 20 Basic Program Use in C, Python, Java, JavaScript with Examples

May 03, 2022 0

Most Important 20+ Program use this same logic find all popular programming language such as C, C++,Python, Java, JavaScript and one so on. 


So In this post discuss most popular and famous Python, C, C++, Java and JavaScript  language used find program all program one by one. These program can be asked from basic use in array, string, pointer, list, loop, condition statement etc. chapter are similarly find all questions. 


Let's see the list of all basic program:- 

  • Write a program add two number. 
Hints How to Find :- c = a+b
Where a, b and c is variable. 
            print(c)

Program 
1. Python 
>>> a=10
>>> b=20
>>> c=a+b
>>> print(c)
30
>>> Done In Python

 

2. C and C++ 

// #include<iostream> // in C++

#include<stdio.h> // in C

#include<conio.h>

int main(){

int a= 10, b=20;

int c=a+b;

printf("Addition in C and C++", C);

 

3. Java

class add{
public static void main(String args[]){
int a=10,b=20;
int c= a+b;
System.out.println("Addition Value in Java: "+c);
}
}

4. JavaScript

<!DOCTYPE html>
<html lang="en">
<head>
    <title>Addition Program</title>
</head>
<body>
    <script>

        // Q1. Addition of two number
    //  var a =10;
    //  var b =20;
    //  var c =a+b;
    //  document.write("Addition Value is:-",+c);
   
// Get user input:-

     var num1 =parseInt(prompt("Enter 1st number:-"));
    var num2 =parseInt(prompt("Enter 2nd number:-"));
    var num3= num1 +num2;
    document.write("Additon value:-", num3);

    </script>
</body>
</html>


Note Important Point  for you:- Well Upper see Addition Program in Diff language like that, C, C++ , Python, Java and Java Script So you can watch all programming language logical are same just change in something syntax  in addition program so used this syntax in our program find given basic program, So Next question. 


Only JavaScript Language Solved all Program
