How to write a program

In this blog I was discuss about how to write a simple
program in any language, because of most of most of the beginners are facing
struggle to write a program, so to avoid that confusion read below article.

First of all clearly understand what the program do and find
out the solution of that. 

Please see the below example:

In this example I was performed arithmetic operations like
Addition, Subtraction, Multiplication and Division.

For any program write an algorithm for that then start
writing of code in your desired programming language.

Algorithm:

Start

Take input for two numbers.

Perform the operation (Addition)

Display the Result

Stop.

Flow Chart for Addition of Two Numbers :

If you observe the above diagram first
it starts the process and take input and perform the operation on it, finally
print the result.

Pseudo code for Addition of two numbers:

Begin

Take two variables A,B.

Assign values to them. (take input)

A =3, B=4;

Print A+B;

End

As a beginner first concentrate about the flow chart and algorithm then it is simple to write the program in any language like C, C++ or Java ...etc.

Addition of two number in C:

#include<stdio.h>

int main()
{
   int a, b, c;

   printf("Enter two numbers to add\n");
   scanf("%d%d",&a,&b);

   c = a + b;

   printf("Sum of entered numbers = %d\n",c);

   return 0;
}

Addition of Two Numbers in C++:

#include <iostream>

using namespace std;

int main()
{
   int a, b, c;

   cout << "Enter two numbers to add\n";
   cin >> a >> b;

   c = a + b;
   cout <<"Sum of entered numbers = " << c << endl;

   return 0;
}

Addition of Two numbers in Java:

import java.util.*;

class SumofTwoNumbers
{
    public static void main(String[] args)
    {
        int a,b,sum;
      
        System.out.println("Enetr a value to A and B:");

        Scanner sr = New Scanner(System.in);

        a = sr.nextInt();

        b = sr.nextInt();

        sum = a+b;

        System.out.println("addition of two numbers is:"+ sum);
    }
}
