求大神可以帮我解释这每行代码分别是什么意思吗？是每行。谢谢了

# include <stdio.h>
# define N 10
void sort(int arr[], int size)
{
int i, j, temp;
for(i = 0; i < N; ++i)
{
temp = arr[i];
for(j = i-1; j>=0 && temp<arr[j]; --j)
{
arr[j+1] = arr[j];
}
arr[j+1] = temp;
}
}
void show(int arr[], int size)
{
int i;
for( i = 0; i < N; ++i )
{
printf("%d ", arr[i]);
}
putchar('\n');
}
int main(void)
{
int array[N] = {73, 22, 93, 43, 55, 14, 28, 65, 39, 81};
sort(array, N);
show(array, N);
return 0;
