Here in this program, we will code to find the sum of series 1/2+4/5+7/8+…. Here n represents the total number of terms we want to add.

C++ program to find the sum of series 1/2+4/5+7/8+…

#include<iostream.h>
#include<conio.h>
#include<math.h>
void main()
{
int i,n;
clrscr();
float sum=0,s,t=1;
cout<<"Calculate the sum of series 1/2+4/5+7/8+\n";
cout<<"Enter the number of terms you want to add: ";
cin>>n;
for(i=0;i<n;++i)
{
s=t/(t+1);
sum+=s;
t+=3;
}
cout<<"The Sum is: "<<sum;
getch();
}

Output:

Calculate the sum of series 1/2 +4/5 +7/8...

Enter the number of terms you want to add: 5
The sum is: 4.01266233
