I have this assignment due in 2 hours and I can't figure out why it is not giving me any output. When I don't set the counters and accumulators to 0 it works, but when I do it doesn't!
Here is the code:
Code:#include<stdlib.h>
#include<stdio.h> //standard library definitions
#include<math.h> //math definitions
#define BAL_HEIGHT 12 //balcony height in feet
#define G 32 //gravitational acceleration in ft/s2
#define PI 3.14159
#define POOL_CENTER 35 //distance to the center of pool
#define MIN_THETA 5 //minimum balloon launch angle in degrees
#define MIN_VEL 1 //minimum balloon launch velocity in ft/sec
#define MIN_THR_HT 4.5 //minimum height of thrower in feet
#define MAX_THETA 85 //maximum balloon launch angle in degrees
#define MAX_VEL 30 //maximum balloon launch velocity in ft/sec
#define MAX_THR_HT 7.0 //maximum height of thrower in feet
#define MIN_DIAM 3 //minimum diameter of balloon in inches
#define MAX_DIAM 9 //maximum diameter of balloon in inches
#define CAPACITY 7 //pool capacity in gallons
int main()
{
