The C++ program is an illustration of loops and conditional statements
<h3>How to analyze the infinite series</h3>
The infinite series is given as:

The above series shows that, the addition and the subtraction signs are interchanged, and the denominator of the fractions increase by 2 while the numerator remains the same
<h3>The main program</h3>
The program written in C++, where comments are used to explain each line is as follows:
#include <iostream>
using namespace std;
int main(){
//This initializes the value of pi to 0
double pi = 0;
//This iterates from 1 to 200000
for(int i = 0; i< 200000; i++){
//The following conditions determine the value of pi
if(i%2==0){
pi+=4.0/(1.0+2.0*i);
}
else{
pi-=4.0/(1.0+2.0*i);
}
}
//This prints the value of pi
cout<<pi;
return 0;
}
