(HackerRank) Write a Modular C Programming code to solve Pi Series computers, Apply Problem Solving Framework to compute the value of pi using the above series
In 1966 Donald G. Fink published a book entitled “Computers and the Human Mind”, which introduced the idea of artificial intelligence as it related to computers. One of the first problems he introduced to illustrate the utility of computers was the calculation of π. It was 1966, and computers were slow, and used punch cards! He postulates that a speed-up comes by way of simple calculation in the form of series.
Fink used a series of the following form:
π = 4/1 – 4/3 + 4/5 – 4/7 + 4/9 – 4/11 + 4/13…
Fink wants to Apply Problem Solving Framework to compute the value of pi using the above series with the help of modular C programming.
Input Format
First-line indicating value of N, the number of terms in the series.
Constraints
N should be greater than or equal to 100.
Output Format
Computed Series for pi.
Sample Input 0
100
Sample Output 0
Pi series = 3.1316
Sample Input 1
10
Sample Output 1
Cannot compute pi series.Refer : C Programming HackerRank all solutions for Loops | Arrays | strings
CODE:
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<math.h>
void pi(int n)
{
int i;
double sum=0;
for(i=0;i<n;i++)
{
sum=sum+4*(pow(-1,i))/((2*i)+1);
}
printf("Pi series = %0.4lf",sum);
}
int main()
{
int n;
scanf("%d",&n);
if(n>=100)
{
pi(n);
}
else
printf("Cannot compute pi series.\n");
return 0;
}
