针对你遇到的问题“error: 'strlen' was not declared in this scope”,以下是一些可能的解决方案和检查点: 确认'strlen'函数的来源: strlen函数是C语言标准库中的一个函数,用于计算字符串的长度。它位于<string.h>头文件中。 检查是否包含了正确的头文件: 确保你的代码中包含了<string.h>头...
宏名称_STRING_H_是为C标准保留的。定义这样的宏是未定义的行为。error

Why wouldn't I be able to use strlen() (which is standard C right?)? What situations require xstrlen() to be used and what would go wrong if you don't? If you have a regular declared character array: static const g_u8_typ crc_TEST_STRING[]= "THE,QUICK,BROWN,FOX,0123456789" ;...
There are library functions available for most of the string operations which are a part of ‘string.h’; header file. However, some of the functions under it are also deprecated and should not be used. We shall have look at them while working with various string operations. ...
This is alright as these bytes are reserved for that array (since you declared strAstro to be 10 elements long initially). Note the presence of the terminating null character. strlen() returns the number of characters in the array, excluding null character. So if we passed strAstro to it...
API/SDK, while strlen() is ANSI C (and part of ISO C++). So if you want your source code to be as portable as possible (to other operating systems) use strlen. Wayne Tuesday, March 8, 2011 5:39 PM | 1 vote Use strlen. The lstrlen function return int type. It is not opportun...
