Interview Time: 2015.07.15Appointment: 2015.07.14, the day before the telephone interview, you will be called to inquire about the time of the telephone interview.Interview session:No self-Introduction (this is the first time I have interviewed so many companies), direct interview content.Question 1: What are the benefits of these projects?Question 2: In the project that has been done, what is the biggest difficulty, how to solve it?Question 3: In 100 million search terms, find out the maximum n

The difference between the two ways of definitionL Memory AnalysisL Drawing AnalysisL The difference between a constant and a variable stringL Constant Memory address viewIv. functions that return pointersThe pointer is also a data type in C, so the return value of a function can certainly be a pointer-typeL The general form of a function that returns a pointer is: type name * Function n

IntroductionSCANF is the system's own function, and the declaration is contained in the stdio.h file, so if you have the function, you must load the #include"The use of attention(1) Use the SCANF function to enter a character variable.Char A; scanf ("%c", a);(2) input multiple values simultaneously: Scanf ("%d,%d", num1,num2);Note: Here the placeholders are, separated, and require commas to be separated as input 1, 2. This is num1=1,num2=2. If intern

Notoginsengprintf"After Swap_any, a=%d, b=%d\n", A, b); - return 0; the +} Implementing an exchange of two integers In the C language, all function arguments are passed by value, that is, the parameter values passed to the called function are stored in the temporary variable, not in the original variable, so the called function cannot directly modify the value of the variable in the key function. At this point we pass the memory a

In summary, there are three types of annotations: 1. Single-line Comment 1: //haha single-line comment2. Multi-line annotations 1: /* 2: asdfasdfasdfasdfasdf 3: * /Where multiple lines of comments are written 1: /* 2: * function is ... 3: * / 4: void dosomething () {...}The compiler can automatically recognize when the mouse clicks on the function name thing. The right side of the system can display the corresponding comment: 1: #include 2: //This is
