#include<stdio.h>
int main()
{
int i,n,sum=0;
printf("\n Enter the n: " );
scanf("%d",&n);
for(i=1;i<=n;i++)
{
if(i%2==0) /* for series is -1 +2 -3.......*/
sum= sum+i;
else
sum = sum-i;
}
printf(" Sum of %d terms is %d \n",n,sum);
return 0;
}
/* For series 1 - 2 +3 ....
then use
for(i=1;i<=n;i++)
{
if(i%2==0)
sum= sum -i;
else
sum = sum +i;
}
