Sort characters in a string (alphabetical order) Program Code

#include <stdio.h>
#include <string.h>

int main() {
    char str[] = "database";
    int len = strlen(str);
    
    printf("Original: %s\n", str);
    
    // Bubble sort
    for(int i = 0; i < len - 1; i++) {
        for(int j = 0; j < len - i - 1; j++) {
            if(str[j] > str[j + 1]) {
                char temp = str[j];
                str[j] = str[j + 1];
                str[j + 1] = temp;
            }
        }
    }
