simple c question

some of you may have looked at my earlier post, basically, i'm making a ecosystem simulation based on the following mathematical model -

(a/b*c) -(d/e*c)+(a/b*c)

there is a ? out of ? chance that an animal will be created, and a ? out of ? chance that something will be destroyed. the math model basically just shows the final amount of animals.

so far what i've got -

Code:

---

#include <stdio.h>
main()
{
     
      float a,b,c,d,e,f,g,h,i;
      printf("number of seconds"); 
      scanf ("%d",&c);
      printf("first number for creation");
      scanf("%d",&a);
      printf("second number of creation");
      scanf("%d",&b);
      printf("first number of destruction");
      scanf("%d",&d);
      printf("second number of desturction");
      scanf("%d",&e);
      f=(a/b*c) -(d/e*c) +(a/b*c);
     
     
      printf("the final amount is %d\n",f);
}

i've tried so many different things...and yet nothing works...
help!!!

thanks in advance,

use %f instead of %d

Thats what I was about to say. Your identifiers are set up as floating point numbers :

Code:

---

float a,b,c,d,e,f;

---

Yet when you call them in your code, you are accessing them as integers:

Code:

---

scanf("%d", &a);

---

Your basicaly confusing the program.

Code:

---

#include <stdio.h>

main()
{
      float a,b,c,d,e,f;
      printf("number of seconds\t"); 
      scanf_s("%f",&c);
      printf("first number for creation\t");
      scanf_s("%f",&a);
      printf("second number of creation\t");
      scanf_s("%f",&b);
      printf("first number of destruction\t");
      scanf_s("%f",&d);
      printf("second number of desturction\t");
      scanf_s("%f",&e);
      f=(a/b*c)-(d/e*c)+(a/b*c);
               
      printf("the final amount is %f\n",f);
}
