can any one give me a code to solve this equation in c++?

Question

X+X^2+X^3........X^n-j

Answer 1

#include #include
#include
void main()
{
int x,j,n;
long int sum;
cout<<"enter the value for x"< cin>>x;
cout<<"enter the value for n and j"< cin>>n>>j;
sum=0;
for(int i=0;i<=j;i++)
{
sum=sum+pow(x,i);
}
cout<<"sum = "< }

Answer 2

I'm not going to do all the work for you. That way you'll never learn.

Have a variable x
Use a for loop for i=1 to 1=n-j
each time round the for loop, have x+=x^i
