scanf("%f%f%f",a,b,c);
要加&,其它的没什么问题了.
给你个更简单的.
#include <stdio.h>
int main(void)
{
    float a,b,c;
    printf("input 3 numbers a b c:");
    scanf("%f %f %f",&a,&b,&c);
    printf("The max one is:%f",a>b?a>c?a:c:b>c?b:c);
    getch();
    return 0;
}

程序代码：

/*
用数组解决一下
*/
#include<stdio.h>
int main(void)
{
        float a[3],max;
        int i;
        char  c;
        for(i=0;i<3;i++)
        {
                printf("请输入第%d个数,enter结束输入：\n",i+1);
                scanf("%f",&a[i]);
                while(c=getchar()!='\n'&&c!=EOF);
        }
        puts(" ");
        max=a[0];
        for(i=1;i<3;i++)
                if(max<a[i])
                        max=a[i];
        printf("max=%f\n",max);

        getch();
}
