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

wap to delete all vowels from a sentence and print the sentence without vowels.

#include<stdio.h>
void main()
{
char sen[1000],sen2[100];
int i,a,count=0,j=0;
gets(sen);
a=strlen(sen);
for(i=0;sen[i]!='\0';i++)
{
 if(sen[i]=='a'||sen[i]=='e'||sen[i]=='i'||sen[i]=='o'||sen[i]=='u')
        count++;
        else
    {
    sen2[j]=sen[i];
    j++;

    }
    }

printf("%d\n%d",i,a);
printf("\n%s",sen2);
}
