程序加载时,该段会被映射到内存的可读写区域。 .bss 段(Uninitialized Data) 用途:存放未初始化或初始化为0的全局/静态变量(如 int y; 或 static int z = 0;)。 特点: 不占用ELF文件的实际空间(仅记录长度),加载时由操作系统分配并清零内存。 提升存储效率(无需在文件中存储大量零值)。 .rodata 段(Read...

value = myStructPtr->myField;// Accessing field of uninitialized struct printf("Value: %d\n", value); return0; } 另一方面,Zig没有任何参考资料。它具有可选类型,在开头用问号表示。只能给可选类型赋值,并且只能在使用关键字或简单地通过表达式检查它们是否为null时引用它们(null引用曾被快速排序算法的创...
明确表示希望所有的构造函数都使用相同的值。避免维护问题。可以生成最短,最高效的代码。 Example, bad(反面示例) 代码语言:javascript 代码运行次数:0 classX{// BADint i;string s;int j;public:X():i{666},s{"qqq"}{}// j is uninitializedX(int ii):i{ii}{}// s is "" and j is uninitiali...

显示:warning: `ulParam' might be used uninitialized in this function 警告原因: 当ulParam做为表达式的右值时,而在此之前,你又没有对这个参数进行初始化。 例如:void Func() { ulong ulParam; ulong ulRetCode; if(…) { ulParam = ……..; ...
Tentativesymbols are those symbols that have been created within a file but have not yet been sized, or allocated in storage. These symbols appear as uninitialized C symbols. The ability of a name in one translation unit to be used as the definition of the same name in another translation ...
