是2-8好不好？

#include?<stdio.h>int?main()
{????
????char?c?=?'a';????
????int?n?=?c;?//將c賦值給n????
????float?f?=?c;???????//將c賦值給f????
????double?d?=?c;?????//將c賦值給d????
????printf("%d\n",n);????
????printf("%f\n",f);????
????printf("%lf\n",d);????
????return?0;???
}

那個(gè)a是有特殊定義的哦

因?yàn)樽址鸻的ASCII碼的十進(jìn)制值就是97.
