Need help debugging code - Program uses function to sort array

I have been working on this all day and cant seem to work anything out.The program accepts the array values and stops. No compiler errors.
:confused:
Any help whatsoever is greatly appreciated!

Code:

---

#include <stdio.h>
#include <stdlib.h>
int *ptr;
int* sort(int numbers[], int size);
int main(int argc, char *argv[])
{
  //declaring variables//
  int x;
  int i;
  int counter;
  int place1;
  int place2;
  int place3;
  int place4;
  int p;
  int size;
 
  //Prompts for and accepts integers//
  printf("How many integers in array?\n");
  scanf(" %d", &size);
  int numbers[size];
 
  for(i=0;i<(size);i++)
  {
  printf("Enter Number #%d  ", i+1);
  scanf(" %d", &numbers[i]);
  }
 
  //sorts array//
  ptr = sort(numbers,size);
 
  //prints sorted array//
  for(p=0;p<size;p++)
  {
  printf(" %d", *(ptr+p));
  }   
 
  system("PAUSE");   
  return 0;
}




int* sort(int numbers[], int size)
{
 //declaring variables//
 int x;
 int smallest;
 int holdsvar;
 int y;
 //sorts array by finding min value//
 for(x=0; x=(size-1) ; x++)
 {
          smallest=x;
          for(y=x; y=(size-1); y++) 
          {
                  if (numbers[y] < numbers[smallest])
                  {
                                  smallest=y;
                  }
          }
 //switches analysed spot(0->array size) with smallest value//
 holdsvar=numbers[x];
 numbers[x]=numbers[smallest];
 numbers[smallest]=holdsvar;
 }       
       
return &numbers[0];
}

Your compiler allows array declarations from local variables?

I'm impressed! :cool:

Make sort a void function, you don't need any return from it, or do have some special purpose in mind here?

Code:

---

for(x=0; x=(size-1) ; x++)

---

Do you know the difference between == and = ?
If not, you need to learn it.
If yes, What do you think this does "x=(size-1)"?

FYI: Making warning go way without understanding them is a bad thing to do.

Yeah, it's a feature added in C99. But I think you use a pre-1999 compiler which doesn't have that feature. ;)

Thank you stahta01.


I was assigning (size-1) to x...ooops

To resolve this i changed

Code:

---

for(x=0; x=(size-1) ; x++)

---

to

Code:

---

for(x=0; x<size ; x++)

---

for both "for" loops in the sort function.
Program works now, thanks guys!
