Using the String class in C + +, there is no limit to the length of the array compared to using the array, and the operation is convenient for adding#include   #include  using namespace std;string jiami ( STRINGSTR,INTK,INTB); String jiemi

Templates are the basis for generic programming . The so-called generic programming is to write type-independent logic code, is a way to reuse. Templates are divided into template functions and template classes.First, we do not use the template

1. There are three sequential containers in the sequential container C + + standard library: vector list deque vector: Supports fast random access, inserting or deleting elements in locations other than the tail may be slow list: Supports fast

Personally think the second kind is more practical, but also the most commonly used ~However, when the calculation algorithm time-consuming, do not forget second, not as long as the milliseconds to reduce, otherwise negative, if the algorithm time

1. Q: Why can't I perform arithmetic operations on void * pointers?A: Because the compiler does not know the size of the value object, the algorithm operation of the pointer is always based on the size of the object being referred to.2. Can the Q:c

First, the summary: Variable size array. Supports fast random access. Inserting or deleting elements at a location other than the tail may be slow.: double-ended queue. Supports fast random access. Insertion/Deletion is fast at the beginning and the
