sizeof

(i) Basic concepts The sizeof operator gives the storage size of its operands in bytes. Operands can be an expression or a type name enclosed in parentheses. The storage size of the operand is determined by the type of operand. (ii) Methods of use

(1) Basic Concepts The sizeof operator provides the storage size of its operands in bytes. The operand can be an expression or a type name enclosed in parentheses. The storage size of the operands is determined by the type of the operands. (2) Usage

Will you use sizeof? (VC) Author blog: http://blog.csdn.net/topcool99/ This article consists of two parts. The first part focuses on how to use sizeof in VC to find the structure size and problems that are prone to, and provides solutions to the

First, the definition: sizeof is an operator (operator) in C/s + +, which simply functions by returning an object or a type's memory byte count. Its return value type is size_t and is defined in the header file stddef.h. In a 32-bit system: The

1. define sizeof is an operator (operator). The function is to return the number of bytes of memory that an object or type occupies. The return value type is size_t. (size_t is defined in the header file Stddef.h, which relies on the value of the

Strlen only works as a counter. It starts scanning from a memory location (which can start with a string, a location in the middle, or even an uncertain memory area, the counter value is returned until the first string Terminator '\ 0' is

sizeof () function 1, what is it?     sizeof is actually an operator, which is the same thing as those +,-, which is parsed when the program is compiled. Although we often see sizeof followed by parentheses, which are similar to functions, they

For character arrays and character pointers: 1. if it appears as a string, the compiler will automatically add a 0 to the string as the Terminator. For example, if you write "ABC" in the Code, the compiler will help you store "ABC \ 0 ". 2. The
