for some reason neither of my drand48() are returning random numbers between 0-1 like they're supposed to... x was resulting in only the inputted number that is n, and y stayed 0
/// Challenge: Darts
/// circle of radius 0.5 inside a 2x2 square
/// throw darts (x) times and calculate random hits
#include <stdio.h>
#include <math.h>
#include <stdlib.h>
int main() {
double n, t, z, a;
int x, y;
printf("How many darts do you want to throw? ");
scanf("%lf", &n);
printf("Okay, let's throw %lf darts\n. . .\n", n);
z = 0;
a = 0;
t = 0;
while (t <= n) {
x = drand48(); /// returns # 0-1
x = x - 0.5; /// puts it on a graph with domain/range -0.5 - 0.5
y = drand48();
y = y - 0.5;
if ((((x^2) + (y^2))^2) <= 0.25) {
z = z + 1;
}
t = t + 1;
}
a = z / (t - 1);
printf("%lf\n", a);
}
/// remember to compile with gcc darts.c -lm
/// remember to run with ./a.out
