然而,程序员就该担负职责以保证所有值都处在要求的范围内以及值不是被无意复制的。 enumcolour{red =3, blue, green, yellow =5} ;/* not compliant *//* green and yellow represent the same value – this is duplication */enumcolour{red =3, blue =4, green =5, yellow =5};/* compliant */...
struct token_s; typedef int BOOL; typedef int INT; typedef int(*PFNTERM)(PTOKEN, BOOL, INT); // C2065: 'PTOKEN' : undeclared identifier 若要解决此问题,请添加合适的前向声明: C++ 复制 struct token_s; typedef int BOOL; typedef int INT; // forward declarations: typedef struct token...
malloc 函数是标准 C 规定的库函数。在标准中明确规定了在其内存分配失败时返回的是一个 “null pointer”(空指针): [7.20.3-1] If the space cannot be allocated, a null pointer is returned. 对于空指针值,一般的文档(比如 man)中倾向于用 NULL 表示,而没有直接说成 0。但是我们应该清楚:对于指针类型...
很多嵌入式编程领域都不推荐/不允许使用malloc函数，可以满足你的偏好；但是内存泄露并不是编程领域最严重...
struct token_s; typedef int BOOL; typedef int INT; typedef int(*PFNTERM)(PTOKEN, BOOL, INT); // C2065: 'PTOKEN' : undeclared identifier To fix this problem, add the proper forward declarations: C++ Copy struct token_s; typedef int BOOL; typedef int INT; // forward declarations: ...

在C/C++语言中没有专门的字符串变量,通常用字符数组来存放字符串。字符串是以“\0”作为结束符。C/C++提供了丰富的字符串处理函数,下面列出了几个最常用的函数。 ● 字符串输出函数puts。 ● 字符串输出函数gets。 ●字符串连接函数strcat。 ●字符串复制函数strcpy。 ● 测字符串长度函数strlen。 字符串是面试...
