Numbers series and their sum
N terms of Natural numbers series and their sum ( 1^2+2^2 + 3^2+4^2+5^2 + 6^2 ..... n^2)
---------------------------------------------------------------------------------------------------
#include <stdio.h>
int main()
{
int i,n,sum=0;
printf("Input the number of terms in the series: \n");
scanf("%d",&n);
for(i=1;i<=n;i++)
{
sum+=(i)*(i); //main logic series generation
}
printf("\nSum of Series upto %d terms : %d \n",n,sum);
return 0;
}
------------------------------------------------------------------------------------------------
N terms of even numbers series and their sum ( 2^2 + 4^2 + 6^2 ..... n^2)
---------------------------------------------------------------------------------------------------
#include <stdio.h>
int main()
{
int i,n,sum=0;
printf("Input the number of terms in the series: \n");
scanf("%d",&n);
for(i=1;i<=n;i++)
{
sum+=(2i)*(2i); //main logic even no's generation
}
printf("\nSum of Series upto %d terms : %d \n",n,sum);
return 0;
}
--------------------------------------------------------------------------------------------------
N terms of odd numbers series and their sum ( 1^2 + 3^2 + 5^2+7^2 ..... n^2)
-----------------------------------------------------------------------------------------------
#include <stdio.h>
int main()
{
int i,n,sum=0;
printf("Input the number of terms in the series: \n");
scanf("%d",&n);
for(i=1;i<=n;i++)
{
sum+=(2i-1)*(2i-1); //main logic odd number generation
}
printf("\nSum of Series upto %d terms : %d \n",n,sum);
return 0;
}
