那里错误了？

#include <stdio.h>

int main()

{

        int age = 15;

        int height = 162;

        double weight = 82.5;

        char is fat = 'y';

    printf("年龄：%d 岁\n", age);

    printf("身高：%d CM\n", height);

    printf("体重：%f KG\n", weight);

    printf("是否属于肥胖儿童%c\n", isfat); 

    /*%d,%f,%c此类符号在后面会有讲解*/

    return 0;    

}
