C++ Program To Print And Find Sum Of Series 1+2+4+8+16+32+. . . N

Problem :- Write A C++ Program To Find Sum Of Given Series 1+2+4+8+16+32+.....n

Logic :- Logic is very simple you need to use one for loop and initialize with 1 and run into numbers of terms condition and increase by multiply of condition like i*=2 and print the value of i .

or sum=sum+i; this statement print the sum of the series .

int i,n,sum=0;

cout<<"Enter The Number Of Terms \n";

cin>>n;

cout<<"\nSeries I sGiven Below\n\n";

for(i=1;i<=n;i*=2)

{

sum+=i;

cout<<i<<" ";

}

cout<<"\n\nSum Of Above Series Is\n";

cout<<sum <<endl;;

return 0;

}

Output:-
