allocator类用于自定义底层内存的分配: template<typenameT>classMyAllocator{public:usingvalue_type = T;usingpointer = T*;MyAllocator() =default;template<typenameU>MyAllocator(constMyAllocator<U>&){}pointerallocate(std::size_tn){returnstatic_cast<pointer>(operatornew(n *sizeof(T))); }voiddeallocat...
一、指针使用、引用的运用 1、指针具有双重赋值的属性:第一重赋值,为指针变量赋值内存地址;第二重赋值,为指针变量所指的内存的存储空间赋予内容。 2、(引用:cpp的特性;“引用”作为函数的参数):"引用"仍然是值传递。和普通变量相比较,“引用”只是不产生变量的临时副本。 1[root@rockylinux tmp]# uname -a2Lin...

指向对象或函数的指针(此时我们说该指针指向 函数或对象),或 对象末尾后指针,或 该类型的空指针值,或 无效指针值。 指向对象的指针表示 该对象所占用的内存的首字节的地址。对象的末尾后指针表示 内存中该对象所占用的存储之后的首个字节的地址。

Null pointer dereferences空指针解引用 Out of bounds checking越界检查 Uninitialized variables未初始化的变量 Writing const data写入常量数据 2、Cppcheck安装 Cppcheck也可以从各种包管理器安装;但是,您可能会得到一个过时的版本。为了获取更新版本,可以访问https://github.com/danmar/cppcheck进行源码安装。
