You can use Fwrite () to write a struct body to a file: Fwrite (&some_struct,sizeof SOMESTRUCT,1,FP); The corresponding fread function can be read again, where the fwrite is given a pointer to a structure and the memory image of the structure is

Ask: Why study for more than a year of C language, still do not understand those input function usage, for example: scanf, getch,gets, etc. For: Summary from now on 、、、、、 Ask: It is too late to sum up these basic knowledge, and the others have

A pointer variable 1. Indirect accessThe value of the pointer variable is the address; the value of the ordinary variable is the data, where "*" is the pointer operator. & is an address operator used to refer to a memory address. By using the &

tags (space-delimited): C + + programming language Introduction: The strings in C + + are divided into two types: C-style string String Class Library For the former, it is an array of char types, but the last one must be ' yes '(We can truncate the
