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() { double balloonLaunchAngle; //input: angle in degrees double balloonLaunchVelocity; //input: launch velocity in ft/sec double throwersHeight; //input: user's height plus balcony height in feet double distanceTraveled; //output: distance the balloon traveled in feet double part1, part2, part3; //distance formula: partial result holders int balloonDiam; //ballon diameter in inches double balloonWater; //amount of water in balloon in gallons int poolWater; //amount of water in pool in gallons int balloonNumThrown; //number of balloons "thrown" int balloonNumHit; //number of balloons that "hit" the pool double hitPercentage; //percentage of balloons that "hit" the pool balloonNumHit=0; balloonNumThrown=0; poolWater=0; /*balloonDiam=rand()%(MAX_DIAM-MIN_DIAM+1)+MIN_DIAM; balloonLaunchAngle=(double)rand()/RAND_MAX*(MAX_THETA-MIN_THETA+1)+MIN_THETA; balloonLaunchVelocity=(double)rand()/RAND_MAX*(MAX_VEL-MIN_VEL+1)+MIN_VEL; throwersHeight=(double)rand()/RAND_MAX*(MAX_THR_HT-MIN_THR_HT+1)+MIN_THR_HT;*/ srand(time(NULL)); while(poolWater<CAPACITY) { balloonDiam=rand()%(MAX_DIAM-MIN_DIAM+1)+MIN_DIAM; balloonLaunchAngle=(double)rand()/RAND_MAX*(MAX_THETA-MIN_THETA+1)+MIN_THETA; balloonLaunchVelocity=(double)rand()/RAND_MAX*(MAX_VEL-MIN_VEL+1)+MIN_VEL; throwersHeight=(double)rand()/RAND_MAX*(MAX_THR_HT-MIN_THR_HT+1)+MIN_THR_HT; switch(balloonDiam) { case 3: balloonWater=0.1; break; case 4: balloonWater=0.2; break; case 5: balloonWater=0.3; break; case 6: balloonWater=0.55; break; case 7: balloonWater=0.8; break; case 8: balloonWater=1.25; break; case 9: balloonWater=1.7; break; } part1=(balloonLaunchVelocity*cos(balloonLaunchAngle*PI/180.0))/G; part2=balloonLaunchVelocity*sin(balloonLaunchAngle*PI/180.0); part3=2*G*(throwersHeight+BAL_HEIGHT); distanceTraveled=part1*(part2+(sqrt(pow(part2,2)+part3))); if(distanceTraveled==35) { poolWater=poolWater+balloonWater; balloonNumHit++; } balloonNumThrown++; } hitPercentage=(balloonNumHit/balloonNumThrown)*100; printf("balloon diameter:%d\n", balloonDiam); // printf("balloon Launch Angle:%f\n", balloonLaunchAngle); // printf("balloon Launch Velocity:%f\n", balloonLaunchVelocity); ///printf("Throwers Hiehgt:%f\n", throwersHeight); //printf("Balloon num thrown: %d\n", balloonNumThrown); // printf("balloonNumHit: %d\n", balloonNumHit); //printf("Distance Balloon Traveled: %f\n", distanceTraveled); printf("%d balloons hit the pool.\n", balloonNumHit); printf("%d balloons were thrown.\n", balloonNumThrown); printf("%.2f %% balloons hit the pool", hitPercentage); return(0); }
