sorting in ascending order using bubble sort with pointers

Question

I have to print pointer parameters in ascending order and I was trying to use bubble sort algorithm, but the compiler doesn't sort in the right order. I'm only allowed to use one function.

void sort3(int *a, int *b, int *c){   
        int array[3]= {*a, *b, *c};
        int temp, i,j;
        for(i=0;i<3;i++){
            for(j=0;j<3-1;j++){
                if(array[j]>array[j+1]){
                    temp=array[j];
                    array[j]=array[j+1];
                    array[j+1]=temp;
                }
            }
        }
    }

Answer 1

You sort the local array array, but you don't "return" the values back to the calling function.

Without knowing the full context it seems like you should assign back to what the pointers are pointing to:

*a = array[0];
*b = array[1];
*c = array[2];
