wap to print the sum of the following series.

(2^2)+(2^2+2^4)+(2^2+2^4+2^6)+...........n terms.




#include<stdio.h>
void main()
{
int i,j,sum,seriesum=0,p,n;
printf("enter the number");
scanf("%d",&n);
for(i=1;i<=n;i++)
{
 p=2,sum=0;
for(j=1;j<=i;j++)
{
 sum=sum+pow(2,p);
 p=p+2;
}
seriesum=seriesum+sum;
}
printf("%d",seriesum);
}

NOTE-  i have compiled this program in codeblocks if u do it in turbo c++  use  conio.h  header file in the beginning  and getch()  a the  last
