Write a C program (estimate.c) that estimates using Monte- Carlo methods. Plot the estimate M/N vs. N, where M is the number of random points within a unit circle and N denotes the number of total random points within a square. To make a figure look more nicely, please take N=1e3, 1e4, 1e5, 1e6, 1e7, and 1e8, and plot the figure with a logarithmic scale for the x-axis (using MATLAB)
