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{//定义...
# How to delete element from Vector How to delete element from Vector: There is tricky thing for deleting in vector loop. The erase method returns the next element after the one you just erased. So you can use that to continue in your loop. vector c; iterator i = c.begin(); while(...
The storage of the vector is handled automatically, being expanded as needed. Vectors usually occupy more space than static arrays, because more memory is allocated to handle future growth. This way a vector does not need to reallocate each time an element is inserted, but only when the additi...
