Introduction:
List is a generalized container of a two-way linked list. Its data elements can be concatenated into linear tables in a logical sense through the linked list pointer. Unlike vector and deque containers that use linear table sequence
Basics:
A. cpp corresponds to an OBJ, and A. obj is a compilation unit. Multiple compilation units are linked through the linker to form an EXE, which is a program. If a CPP needs a function defined by another CPP, you only need to write the
