寫壹個方法，求3個double類型變量的最大值，並返回(用C語言編程)

#include <stdio.h>

double maxfun (double x, double y,double z){

double v;

v = x;

if (y>v) v= y;

if (z>v) v=z;

return v;

}

int main()

{

double a,b,c;

printf("input a b c\n");

scanf("%lf %lf %lf",&a,&b,&c);

printf("Maximum value is: %lf\n",maxfun(a,b,c));

return 0;

}
