C + + interview topics collected during the job searchThe difference between C's struct and C + + struct BODY1, C in the structure of the body does not allow the existence of functions, C + + allows an internal member function, and allows the

These two classes are inherited from Abstractstringbuilder,abstractstringbuilder with two member properties1 Char [] value; 2 int count;The former is used to store strings, which are used to count how many bits are actually used, that is, the actual

This blog is still based on Google's official document as the main line, the code example is completely taken from a demo project we are developing, through a period of previous attempts, the feeling that this combination of ways is more conducive

Yesterday, the senior again out of the test test, let us implement similar to the string class of No mystring class, at first very headache, but really in the writing code when I was very excited to find that this process is really a very valuable

programming exercises (harder than C) (91-100) 91. Write a C function that gives the number of bits in a byte that are placed in 1. "Reference Answer" unsigned int TestAsOne0 (char log) { int i; unsigned int num=0,

1. Conceptually differentiated:A copy constructor is a constructor, and an assignment operator is a category of operator overloading, which is usually a member function of a class2. Differentiate from prototypes:Copy constructor prototype ClassType (

/****************** There are two differences between the copy constructor and the value assignment operator overloading ******** *******************/   1. Copy the constructor to generate a new class object, but the value assignment operator cannot.

Basic programming skills for C ++/C programmers.1. Enter the if statement for BOOL, float, and comparison between pointer variables and "zero value. (10 points) Tip: here, the "zero value" can be 0, 0.0, false, or "Null Pointer ". For example, the

1 Programming Basics1.1 understanding of basic concepts: the difference between const char *, char const *, and char * const is almost the same as that in each C ++ interview.In fact, there are only three declarative methods that are very similar

Requirements: Write a string class, construct, copy, assign values, deconstruct, and so on. Class string { Public: String (const char * STR = NULL); // common Constructor String (const string & other); // copy the constructor ~ String (void); //

Question 5: Write a function to shift n loops of a char string to the right. For example, if "abcdefghi" is n = 2, it should be "hiabcdefgh" after the shift" The function header is as follows:// Pstr is a pointer to a string ending with '\ 0' //

Chapter 2 class constructor, destructor, and assignment functionConstructors, destructor, and assignment functions are the most basic functions of each class. They are so common that they are easy to paralyze. In fact, these seemingly simple
