Write a C Program to calculate 1+2+….n sum of series.

#include<stdio.h> 

void main()
{
	int n,i,sum=0;
	printf("Enter the max values of series: ");
	scanf("%d",&n);
	sum = (n * (n + 1)) / 2;
	printf("Sum of the series: ");
i=1;
    while (i<=n)
     {
       if (i!=n)
printf("%d + ",i);
       else
printf("%d = %d ",i,sum);
i++;
      }
	getch();
}
