C code using Simpson’s 3/8 rule or Simpson’s three by eight rule

Problem: Here we have to find integration for the (1/1+x*x)dx with lower limit =0 to upper limit = 6


Step 1: input a,b,number of interval n

Step 2:h=(b-a)/n

Step 3:sum=f(a)+f(b)

Step 4:If n is odd

Then , sum=sum+2*y(a+i*h)

Step 5: else, When   n I s even
Then, Sum = sum+3*y(a+i*h)

Step 6:Display output=sum *3* h/8
