simple program calculate the sum using for loop (POP) (137)

#include<iostream>

using namespace std;

int main()

{

float x,sum,no_row;

int i,n;

cout<<"input the number:";

cin>>x;

cout<<"enter the number of term:";

cin>>n;

sum =1; no_row = 1;

for (i=1;i<n;i++)

{

  no_row = no_row*x/(float)i;

  sum =sum+ no_row;

}

cout<<"the sum is:"<<sum;

cout<<endl;

}
