Why there is no Tzuyu ? Why does sizeof (x++) not increment x?There is not sizeof operator in Java. If sizeof …(T) is zero, there is no member type.
Register return short signed sizeof static. C-如何找到'sizeof '(指向数组的指针)?? How to find the'sizeof '(a pointer pointing to an array)? For example, sizeof (a), where a is integer, will return 4. Sizeof () this function is an alias of the count() function.如何find'sizeof '(一个指向数组的指针)?? How to find the'sizeof '(a pointer pointing to an array)? 还有其他一些重要的运算符,包括的sizeof 和?? There are few other important operators including sizeof and? 类似于sizeof 操作符,decltype不对其操作数求值。 Like the sizeof operator, decltype's operand is not evaluated. Sizeof (bool)的值为实现定义,而且可以异于1。The value of a sizeof (bool) is implementation defined and might be different from 1. 永远也不必乘上sizeof(char),因为根据定义,sizeof (char)严格为1。 Sizeof(char) is not really necessary, since the size of char is 1 by definition. 例如,sizeof (char)返回1,因为char类型是1字节长数据类型。 For example, sizeof (char) commonly returns 1, since it is one byte large. 两个glVertexAttribPointer调用的倒数第二个参数都是5*sizeof (GLfloat)。 The second last argument to both glVertexAttribPointer calls is 5*sizeof (GLfloat). Sizeof (bool)的值是由实现定义的,可能不等于1。The value of a sizeof (bool) is implementation defined and might be different from 1. 要获取一个类型或在特定平台上的变量的确切大小,可以使用sizeof 方法。 To get the exact size of a type or a variable on a particular platform, you can use the sizeof method. Sizeof 返回的值是一个常数,因此它总是在程序执行前就被固定了。The value returned by sizeof is a constant, so it is always determined before program execution. 如需得到一个类型或一个变量在特定平台上的准确大小,可以使用sizeof 方法。 To get the exact size of a type or a variable on a particular platform, you can use the sizeof method. 相应的,sizeof (src)运算符表示的不是数组的大小,而是指针的大小。 Correspondingly, the sizeof (src) operator evaluates not the array size, but the size of the pointer. 为了得到一个类型或在特定平台上的变量的确切大小,可以使用sizeof 操作符。 To get the exact size of a type or a variable on a particular platform, you can use the sizeof operator. 比如,SizeOf (Longint)返回4,因为一个Longint变量使用4个字节的内存。 In 64-bit iOS SizeOf (LongInt) returns 8, since a LongInt variable uses eight bytes of memory. 我们可以发现任何值的宽度,它的类型的width使用unsafe.Sizeof ()函数:. We can discover the width of any value, and thus the width of its type using the unsafe. Sizeof () function. 五、sizeof的主要用途1、sizeof 操作符的一个主要用途是与存储分配和I/O系统那样的例程进行通信。 EXAMPLE 1 A principal use of the sizeof operator is in communication with routines such as storage allocators and I/O systems. 例如,一个三角形包含三个顶点,因此该三角形的缓冲区大小是:3*sizeof (CUSTOMVERTEX)。 For example, a triangle contains three vertices, so the size of the triangle's buffer is: 3* sizeof (CUSTOMVERTEX). 我认为我的编译器有问题:我注意到sizeof ('a')是2而不是1(即,不是sizeof (char))。 I think something's wrong with my compiler: I just noticed that sizeof ('a') is 2, not 1(i.e. not sizeof (char)). 现在,Linux内核已支持SIZEOF_FIELD,FIELD_SIZEOF ,sizeof_field作为计算C结构成员大小的方法。 The Linux kernel to now has supported sizeof _FIELD, FIELD_sizeof, sizeof _field as means of calculating the size of a member of a C struct…. 早在C++还未完全标准化的1997年,布莱恩·帕克(BrianParker)就基于sizeof 操作符,提出了一种可移植的解决方案。 As early as 1997, before C++ was fully standardized, Brian Parker proposed a portable solution based on the sizeof operator.
