--------------------------------file-----------------------------------
Fin.open (file name); Open file read-in, not empty file
Fin.close (); Close file read-in, must, otherwise cannot open another file
Fout.open (file name); Open file output, will empty the file
Fout.close (); Close the file output, be sure, otherwise you cannot open another file
Ofstream (file name); Create a file
DeleteFile (file name); Delete file
If you want to open a file, the file name is given a string or string plus a string, so write it like this:
String s= "123456";
Fin.open ((s+ ". txt"). C_STR ());
Fout.open ((s+ ". txt"). C_STR ());
To create and delete files:
String s= "123456";
Ofstream ((s+ ". txt"). C_STR ());
DeleteFile ((s+ "txt"). C_STR ());
You can also write this:
String s= "123456.txt";
Fin.open (S.c_str ());
Fout.open (S.c_str ());
Ofstream (S.c_str ());
DeleteFile (S.c_str ());
fin>>x; Read X in File
fout<<x; Export x to the file

How to use: For example, dark red background color, light white font color, A is 64+15=79
-------------------------icon Position---------------------------------
HANDLE Hout=getstdhandle (Std_output_handle); Handle
SetConsoleCursorPosition (Hout,{y,x}); Go to the X, y, and y, and note that X and Y are in reverse, written as {y,x}
-------------------------Clear Screen-------------------------------------
System ("CLS");
-------------------------wait-------------------------------------
Sleep (x); Wait x milliseconds
-----------------------key to determine-----------------------------------
Key_down (c); Judging the button press, the screen does not display
Determine whether to press C
The return value is 0 or 1, press 1, otherwise 0
Note: is to determine whether to press C, not to get the key pressed letters, if you judge the number, you must press the number of the row above
Can not use the keypad, F1, small keyboard, shift and other keys to use the Virtual Key Code table, the following one will be used.
#define Key_down (Vk_noname) ((Getasynckeystate (vk_noname) & 0x8000)? 1:0) Required header files
#include <windows.h> required header files
int b;
while (1==1) dead loop
{
b=0;
B=key_down (' 1 '); To determine the button press
if (b) cout<<1; If the key press is 1, the output 1
}

Program Description: ESC's virtual key table is 0x1b, enter enter for 13,↑ to 72,↓ for 80,← to 75,→ for 77
If you press ESC to exit if you press ↑, output up,↓, output down,←, output left,→, output righr
Recommendation: Write it as a function to change the output of printf 4 rows to call other functions, return values, etc.
Upgrade version:
int F;
F=getch ();
if (f==224)
F=getch ();
When f=224, that is, press ↑↓←→ and then take the F
F Common values:
Enter

---------------------------The calling program--------------------------------
WinExec (file path, 1);
File path \ To be changed to//, such as: I want to call D:\a\b\c.exe, will be written D://a//b//c.exe
If you want to open an. exe file in the same folder as the running program, but do not know the location of the file, or know the location of the file, the \//is a bit difficult, can be written C.exe,
If you want to open an. exe file under one or more folder directories under the folder where the program is running, but do not know the location of the file, or know the location of the file, the \//is a bit difficult, can be written as A//b//c.exe.

--------------------------------function Declaration---------------------------
int a (); function declaration
int B (); function declaration
int A ()
{
b (); Call the B function, because the function declares that all can call B
}
int B ()
{
A (); Call a function
}
--------------------------------Program Calls---------------------------
WinExec ("X://xx//xxx.exe", f);
"" is the path, F is the passed-in value
Example: WinExec ("d://guess number//guess number//guess Number.exe", 1);
If you want to invoke files within a file or folder in your own directory:
WinExec ("Xxx.exe", f);
WinExec ("Xx//xxx.exe", f);
Cases:
WinExec ("Guess number.exe", 1);
WinExec ("Guess number//guess Number.exe", 1);
--------------------------------program Window---------------------------
System ("title timer"); Change the title and change the program name in Task Manager at the same time
System ("mode con cols=x lines=y"); x row y column, non-pixel point
HWND Hdos=getforegroundwindow (); Hide, show handle to Window
ShowWindow (Hdos,sw_hide); Hide Window
ShowWindow (hdos,sw_show); Display window
