### 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);
}
}```
