This thing was accidentally seen some time ago. although I have already learned C ++, I cannot say that I am proficient .. so I need to study these books carefully in the future .. I hope it will be useful to you. several of them are quite classic

Some books on the market use void main (), which is actually incorrect. Void main () has never been defined in C/C ++ () . The father of C ++ Bjarne stroustrup clearly states the definition void main (){ /*... */} Is not and never has been c ++, nor

References are a concept in C ++. Beginners can easily confuse references with pointers. In the following program, n is M's oneReferences, and M is a referenced object (referent ).Int m;Int & n = m;N is equivalent to M alias (nickname). Any

1. This concept must be distinguished by pointer assignment and pointer assignment. Assign values by pointer: indicates the value of the memory area pointed to by the update pointer. Assign a value to the pointer: changes the address to which the

Summary: The value assignment operator and replication initialization are usually used together. Both of them have merged versions. Sometimes you don't need to worry about them. In addition, private: Class (const Class &) can prevent the user code

In C ++, the string class is designed in the standard library for the difficulty of processing strings in C language. Therefore, the string class can be directly used if string processing is involved in programming.    The reason why the char *
