Problem # 3:
Write a program that displays the sum of the following series using do-while loop.
1 + 1/4 + 1/8 + ... + 1/100
Solution:
#include<iostream>
#include<conio.h>
#include<iomanip>
using namespace std;
int main()
{
float n=4,sum=1;
do
{
sum=sum+1/n;
n+=4;
}
while(n<=100);
cout<<"The sum of the series is:"<<setprecision(4)<<sum<<endl;
return 0;
}
#include<conio.h>
#include<iomanip>
using namespace std;
int main()
{
float n=4,sum=1;
do
{
sum=sum+1/n;
n+=4;
}
while(n<=100);
cout<<"The sum of the series is:"<<setprecision(4)<<sum<<endl;
return 0;
}
