A monte carlo assignment, no print statements are written yet

EDIT: Due at midnight, fg donations for help

basically to throw darts at a target on a rectangle thats 20x20 maxes=10 mins=-10 the target is a circle in the dead center centered at 0,0 witha radius of 3

getting various errors with vim

expected expression before 'double on the x = double y = double and those are my only errors, however when i delete the 'double' i get all these odd errors and my file gets deleted somehow

here it is

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <math.h>
#define PI 3.14159
#define RADIUS 3

int main (int argc, char *argv[])
{
int dNum, seed;
int recArea = 400;
int hits = 0;
int p = 0;
double x, y;
double xmin = -10, xmax = 10, ymin = 10, ymax = 10;
srand(seed);

printf("Enter the random number seed:\n");
scanf("%d", &seed);
printf("Enter the number of darts to throw:\n");
scanf("%d", &dNum);

void getBorders (double *xmin,double *xmax,double *ymin,double *ymax);

for (p=1; p<=dNum; p++) {
x = double RandNumInRange(*xmin, *xmax);
y = double RandNumInRange(*ymin, *ymax);
int DartHits(x,y);
if (DartHits(x,y) == 1) {
hits++;
}
}

double RandNumInRage(double minval, double maxval)
{
double value;
value = rand() / RAND_MAX * (2 * maxval) + minval;
return value;
}

int DartHits (double x, double y)
{
if (sqrt(x*x+y*y) <= RADIUS) {
return 1;
} else {
return 0;
}
}
return 0;
}

if you're trying to cast, use (double)

x = (double) RandNumInRange(xmin, xmax);
y = (double) RandNumInRange(ymin, ymax);


I changed it to that and got


mcint.c: In function 'main':
mcint.c:28: warning: parameter names (without types) in function declaration
/usr/bin/ld: unrecognised emulation mode: cint.c

EDIT

now

You're not defining your 'DarkHits' properly, also "RandNumInRange" is not a function

Look into
