排序算法之一---选择排序

#include <stdio.h>
void selection_sort(int arr[],int length)
{
    int i,j;
    for (i = 0; i < length; i++){
        int minval_index = i;
        for (j = i+1; j < length; j++){
            if (arr[j] < arr[minval_index]){
                minval_index = j;
            }
        }
        int temp = arr[i];
        arr[i] = arr[minval_index];
        arr[minval_index] = temp;
    }
}

int main(int argc, char **argv)
{
    int arr[] = {6,4,5,67,78,45,534,5,57,65,75,346,8,54};
    selection_sort(arr,sizeof(arr)/sizeof(int));
    int i;
    for (i = 0; i < sizeof(arr)/sizeof(int); i++){
        printf("%d ",arr[i]);
    }
    
    return 0;
}
