在C++中,<vector>是一个标准库头文件,它包含了std::vector容器类,这是一个动态数组。要在C++代码中包含这个库,你需要在文件的开头添加以下代码: 代码语言:cpp 复制 #include<vector> 在C++中,<algorithm>是一个标准库头文件,它包含了许多通用的算法,如std::sort()和std::find()。要在C++代码中包含这个库,...
结构体 Cpp 中的 struct 不同于 C 中的 struct,cpp 的 struct 被扩展为类似 class 的类说明符。 结构体是一系列成员元素的组合体,允许存储不同类型的数据项,成员变量可以是各种数据类型,包括整数、浮点数、字符串、其他结构体等,所以你可以根据需要定义自己的结构体来组织数据。 定义结构体 cpp structMyStruct{...

vector类型可以直接添加,Vector最多支持二维,超过二维需要先创建node数组再加入 初始化添加 Json json2={ {"float",12.3}, {"int",23}, {"bool",true}, {"str","string"}, {"null",nullptr}, {"stdstr",string("chenxuan")}, {"arrFloat",{2.3,8.9,2.3}}, {"arrBool",{true,false}}, {"ar...

there is no theoretical limit on the number of elements of a vector, but inserting many elements at a time will force a capacity increase of the vector, which can become a heavy operation. You can use the capacity() member function in order to find to what size can the vector grow to...
