how to sort arrays in ascending order in c language

/*
Example: sort array in ascending order using C language
*/

#include <stdio.h>
#include <stdlib.h>

void printArr(int* arr,int len){
    for (int i = 0; i < len; ++i){
        printf("%d ",arr[i]);
    }
    printf("\n");
}

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

    int num[] = { 1,6,7,9,3,5,4,2,17,12};

    int len = sizeof(num)/sizeof(num[0]);
    int temp;

    printArr(num,len);
    for (int i = 0; i < len; ++i){
       for (int j = i + 1; j < len; ++j){
          if (num[i] > num[j]){
             temp = num[i];
             num[i] = num[j];
             num[j] = temp;
          }
       }
    }

    printArr(num,len);
    return 0;

}

example of output:

1 6 7 9 3 5 4 2 17 12
1 2 3 4 5 6 7 9 12 17
