intcharSize=Character.BYTES; 1. 上述代码定义了一个整型变量charSize,并将其初始化为Character.BYTES,它表示char类型的大小。 输出char类型的大小 最后,我们将输出char类型的大小。可以使用如下代码输出char类型的大小: System.out.println("The size of char is "+charSize+" bytes."); 1. 上述代码使用System...
byte 8bit char 16bit float 32bit double 64bit boolean 1bit,This data type represents one bit of information, but its "size" isn't something that's precisely defined.(ref) Java基本数据类型大小 private static void calSize() { System.out.println("Integer: " + Integer.SIZE/8); // 4 Sy...

因为char只占用1个字节,所以char szBuf256占用256个字节,即: sizeof(szBuf) == 256 _countof(szBuf) == 256 // _countof函数意思是求数组的长度 得到的是一样的结果。 所以in bytes的时候,传入sizeof(szBuf)就行了。比如我在《sqlite的C语言使用》讲过的sqlite3_prepare函数,第三个参数就传入sizeof(z...
