C语言程序设计教程（第三版）课后习题9.8 （C语言代码）利用三目运算符

#include <stdio.h>

#define max(a,b,c) (a>b?a:b)>c?(a>b?a:b):c

float max_1(float a,float b,float c)

{

    if(a>b)

        return (a>c?a:c);

    else

        return (b>c?b:c);

}

int main (void)

{

    float a,b,c;

    scanf("%f %f %f",&a,&b,&c);

    printf("%.3f\n",max(a,b,c));

    printf("%.3f\n",max_1(a,b,c));

    return 0;

}
