当宣告C/C++的built-in type后,必须马上initialize该变量的值,因为C/C++在宣告变量时,仅为该变量配置了一块内存,却没对该变量设定任何初始值,所以该变量目前的值为宣告该变量前所残留的值,虽可直接使用该变量,但并没有任何意义。 尤其在使用array时,当宣告完array及其大小后,第一件事情就是为array中所有element...
or fewer characters in a string literal used to initialize an array of known size than there are elements in the array, the remainder of the aggregate shall be initialized implicitly the same as objects that have static storage duration. ...
下面是C99中原话: Except when it is the operand of the sizeof operator or the unary & operator, or is a string literal used to initialize an array, an expression that has type ‘‘array of type’’ is converted to an expression with type ‘‘pointer to type’’ that points to the ini...
An array can be initialized while being declared. For instance, int mark[5] = {19, 10, 8, 17, 9}; C initialize array can be done using this formula: int mark[] = {19, 10, 8, 17, 9}; Here, the size is left unspecified. However, because we initialize it with 5 elements, th...
We can initialize a string variable in C by assigning it characters individually and specifying the maximum size of the string as an array size. The syntax and an example for this are given ahead. Syntax: char array_name[static size] = {'C', 'H',' A', 'R', '\0'} Code Example...
A designator causes the following initializer to initialize of the array element described by the designator. Initialization then continues forward in order, beginning with the next element after the one described by the designator. int n5 = {4=5,0=1,2,3,4} // holds 1,2,3,4,5 int aMAX...
A string literal like _T("C:\AAA") should not be modified, so it should be considered const, i.e. const TCHAR*, i.e. LPCTSTR. The OP might have better help if he gives more context. Maybe he wants a TCHAR array that can be modified? Or is a const TCHAR*/LPCTSTR just what ...
在debug版本下指针默认初始值为0xCCCCCCCC,在Release版本下初始值为0x0000000A,(在我电脑上VC6.0)。对于指针如果暂时没有合适的初始化值,就应该把它置为NULL(0)。 对于好的编程习惯来说,declare一个指针,则初始化为NULL,如果是类成员 则在构造函数中initialize,当对指针使用delete时候,则置它为NULL. ...
string literal used to initialize an array, an expression that has type ‘‘array of type’’ is converted to an expression with type ‘‘pointer to type’’ that points to the initial element of the array object and is not an lvalue. If the array object has register storage class, the...
