表达式小题

写一个表达式,如果a>b 返回+1,a==b 返回0 a<b 返回-1:

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

inline int hello(int a, int b)
{
    return (a==b?0:1)?(a>b?1:-1):0;
}

int main()
{

    printf("%d\n",hello(8,9));
    printf("%d\n",hello(9,9));
    printf("%d\n",hello(9,8));

    printf("-------\n");
    printf("%d\n",hello(0,1));
    printf("%d\n",hello(0,0));
    printf("%d\n",hello(1,0));
    return 0;
}
