Code:

#include <stdio.h>
#include <math.h>
#include "drand.h"
#define PI (4*atan(1))
int main(void)
{
double A, t, T, p, n, w, y, a, b, c;
A=drand()+1;
T=((drand()+1)*10);
w=(2*PI/T);
p=drand()*2*(4*atan(1));
for(t=0; t<=50; t++)
{ n=(drand()*.6-.3)*A;
y=A*sin( w*t + p) + n;
printf("%f %f \n\n", t, y);
}
return 0;
}

Now modify the program so that while generating the data it uses some method, of your choice, to produce a good estimate of the period from the data. The estimate must be based only on the y values, and could for example use a sliding window.

Then, at the end, generate separate sine data using your sine function with w based on the estimated period, the original values of A and p, and no noise, to plot over the same range of t with points and lines.

It orginally plots just points, now i need to plot a line in addition (along the points as much as possible).Thanks in advance and please keep it real simple if possible.
