, and the last read of the string is read into the line feed. Therefore, when you call the Fgets function, you can read a maximum of n-1 characters. At the end of the read, the system will automatically add ' + ' at the end and return with STR as the function value.2.2 fputs functionThe Fputs function is used to output a string to a file. The Fputs function is called in the following form:Fputs (str, FP);Here, the FP is the file pointer; Str is the string to be output, which can be a string cons

Why a constructor cannot be a virtual functionC++ From the storage space point of view, the virtual function corresponds to avtableA pointer to a virtual function table, which we all know, but this pointvtableThe pointer is actually stored in the object's memory space. The problem is that if the constructor is virtual, you need to passvtableTo invoke, but the object is not instantiated, that is, the memory space is not yet, how to findvtableIt? So the constructor cannot be a virtual f

function is a kind of encapsulation supported by Python, we can decompose complex tasks into simple tasks by splitting large pieces of code into functions through a layer of function calls, which can be called process-oriented programming. function is the basic unit of process-oriented program design.Incoming functionThe function itself can also be used as a parameter.
