正確：

#include <stdio.h>
int main()
{
??? int age = 15;
??? int??? height = 162;
??? float??? weight = 82.5;
??? char??? isfat = 'y';
??? printf("年齡：%d 歲\n", age);
??? printf("身高：%d CM\n", height);
??? printf("體重：%f KG\n", weight);
??? printf("是否屬于肥胖兒童：%c\n", isfat);
??? /*%d,%f,%c此類符號在后面會有講解*/
??? return 0;???
}

錯誤：

#include<stdio.h>
int main()
{
?int age = 15;
?int height = 162;
?float weight = 82.5;
?char isfat = 'y';
?printf ("年齡；%d 歲\n"，age);
?printf ("身高；%d CM\n",height);
??? printf ("體重；%f KG\n",weight);
??? printf ("是否屬于肥胖兒童；%c\n",isfat);
??? return 0;
}

求教！！
