C programming: arrays in ascending order?

Question

say I have the array [5,7,1,9,2], I want it to be in ascending order so obviously the array would then be [1, 2, 5, 7, 9]. how can I do this using the bubblesort algorithm?

Answer 1

hm. simply implementing the bubble algo... surely an already done code is out there, you have just to pass your array in.

like

bubblesort(myarray,NUM);

if myarray is

int myarray[NUM]; or something like this

Answer 2

Just use one of the stdlib sort routines.  Here's how to do it with qsort.

#include <stdlib.h>

int myArray[5] = {5,7,1,9,2};

int ascendCompare(const void *a, const void *b) {

   int a_val = *((int *)a);

   int b_val = *((int *)b);

   return a_val - b_val;

}

int main(int argc, char*argv[]) {

   qsort(myArray, 5, sizeof(int), ascendCompare);

}
