Series Pattern Program for 1 + 2 + 3 + 4 + 5 + … + n

This article discusses, how to write a prorgram to solve 1 + 2 + 3 + 4 + 5 + … + n series in python, C, C++ and Java.

Problem Definition

Write a prorgram to solve 1 + 2 + 3 + 4 + 5 + … + n series in python, C, C++ and Java.

Sample input and Output:

Enter the value of n: 10

Sum is: 55

Source code to solve the series 1 + 2 + 3 + 4 + 5 + … + n in python

sum = 0
n = int (input("Enter the value of n:"))
for i in range(1,n+1):
    sum = sum + i
print ("Sum is: ", sum)

Source code to solve the series 1 + 2 + 3 + 4 + 5 + … + n in C

#include <stdio.h>
int main()
{
    int i,n,sum=0;
    printf ("Enter the value of n:");
    scanf ("%d", &n);
    for(i=1;i<=n;i++)
    {
        sum+=i;
    }
    printf("Sum is: %d",sum);
    return 0;
}

Source code to solve the series 1 + 2 + 3 + 4 + 5 + … + n in CPP (C++)

#include <iostream>
using namespace std;
int main()
{
    int i,n,sum=0;
    cout << "Enter the value of n:";
    cin >> n;
    for(i=1;i<=n;i++)
    {
        sum+=i;
    }
    cout << "Sum is: " << sum;
    return 0;
}

Source code to solve the series 1 + 2 + 3 + 4 + 5 + … + n in Java

import java.util.Scanner;
class Series1
{
    private static Scanner scan;
    public static void main(String[] args)
    {
 	int i, n, sum = 0;
	scan = new Scanner(System.in);
	System.out.println("Enter the value of n:");
	n = scan.nextInt();
	for(i=1;i<=n;i++)
	{ 
   	    sum+=i;
	}
	System.out.print("Sum is: " + sum);
    }
}
