Im not sure why this bubble sort code isn't working at all, could someone give me a hint ?

Help would be much appreciated. Thanks.

Code:#include <stdio.h> #include <stdlib.h> #include <ctype.h> #include <string.h> int array[2]; int temp[2][2]; int checkint(char s[]) //Checks if string is purely numerical { int length = strlen(s); // Define string length for (int i = 0; i < length; i++) // For each character { if (isdigit(s[i])); // If numerical, then do nothing else return 0; //If not, then return 0 } return 1; } static void bubble_sort(int r[], int y) { int i, j, temp; for (i = 0; i < y-1; i++); for (j = 0; j < y-i-1; j++); if (r[j] > r[j + 1]) { temp = r[j]; r[j] = r[j + 1]; r[j + 1] = temp; } } int main(int argc, char *argv[]) { int temp = (argc - 2); array[temp]; if(argc < 2) //Check if enough arguments have been supplied { printf("Too few arguments for this program.\n"); exit(EXIT_FAILURE); //If not then exit } else { for (int i = 1; i < argc; i++) //For every argument provided (excluding 0) { int ans = atoi(argv[i]); //Find the int equivalent int var = (i-1); array[var] = ans; //Store it in the array } bubble_sort(array, argc); for (int a = 0; a < argc-1; a++) printf("%d ", array[a]); printf("\n"); } // Exit indicating success exit(EXIT_SUCCESS); return 0; }
