clrscr(); equivalent in Code::Blocks
提问by gandalf
how to clear the output console in code blocks?? why doesn't clrscr(); work in Code::Blocks but works in Borland??
如何清除代码块中的输出控制台？为什么没有 clrscr(); 在 Code::Blocks 中工作但在 Borland 中工作？？
I have already tried:
我已经尝试过：
cout << "\x1b[2J\x1b[1;1H" << flush;
cls() ;

The easiest most straightforward way is to just do it through systemfunction call:
最简单最直接的方法是通过system函数调用来完成：
#include <stdlib.h>
int main()
{
system("cls");
}
If you want to do it programmatically MSDN shows how here.
如果您想以编程方式执行此操作，MSDN 在此处显示了方法。
Note that there is no standard function provided by C++ for clearing the console. Some compilers, like borland, provides it as a non-standard function for convenience but it's not portable between different compilers.
请注意，C++ 没有提供用于清除控制台的标准函数。一些编译器，如 borland，为了方便起见，将其作为非标准函数提供，但它不能在不同编译器之间移植。

This is actually a quite simple problem. All you have to do is use printf. You don't even need printf or any headers, for that matter.
这实际上是一个非常简单的问题。您所要做的就是使用 printf。就此而言，您甚至不需要 printf 或任何标题。
printf("\e[1;1H\e[2J");
The \e[1;1H sets the screen to the 1st row and 1st column. the 2J overwrites all characters currently on the screen.
\e[1;1H 将屏幕设置为第一行和第一列。2J 覆盖当前屏幕上的所有字符。
You can also use this:
你也可以使用这个：
write(0,"\e[1;1H\e[2J",12);
Then you don't need stdio.h.
那你就不需要stdio.h了。

You can use the OS commands to clear the contents of the console.
您可以使用操作系统命令清除控制台的内容。
#include<stdlib.h>
int main(){
system("cls"); //For windows
system("clear"); //For Linux
}

I just searched on the internet.
我刚刚在互联网上搜索。
Can't remember the source, but this should be the most accurate so far.
不记得出处，但这应该是迄今为止最准确的。
#include<windows.h>
void clear_screen ()
{
DWORD n; /* Number of characters written */
DWORD size; /* number of visible characters */
COORD coord = {0}; /* Top left screen position */
CONSOLE_SCREEN_BUFFER_INFO csbi;
/* Get a handle to the console */
HANDLE h = GetStdHandle ( STD_OUTPUT_HANDLE );
GetConsoleScreenBufferInfo ( h, &csbi );
/* Find the number of characters to overwrite */
size = csbi.dwSize.X * csbi.dwSize.Y;
/* Overwrite the screen buffer with whitespace */
FillConsoleOutputCharacter ( h, TEXT ( ' ' ), size, coord, &n );
GetConsoleScreenBufferInfo ( h, &csbi );
FillConsoleOutputAttribute ( h, csbi.wAttributes, size, coord, &n );
/* Reset the cursor to the top left position */
SetConsoleCursorPosition ( h, coord );
}
Now, all you have to do is callclear_screen()
现在，你所要做的就是打电话clear_screen()

Create own function in own header file which contain clrscr() and use it. for example :
在包含 clrscr() 的头文件中创建自己的函数并使用它。例如 ：
#include <stdlib.h>
void clrscr()
{
system("cls");
}
save it as "ClearScreen.h" at your path of "include" folder (for ex - C:\Program Files (x86)\CodeBlocks\MinGW\include)
在“include”文件夹的路径中将其另存为“ClearScreen.h”（例如 - C:\Program Files (x86)\CodeBlocks\MinGW\include）
compile it.
编译它。
now use it in your programs like :
现在在您的程序中使用它，例如：
#include <stdio.h>
#include <conio.h>
#include <ClearScreen.h>
main()
{
clrscr();
printf("\nHi");
getch();
return 0;
}
now compile and run it. i hope it works....
现在编译并运行它。我希望它有效....

#include <stdlib.h>
int main()
{
system("cls");
}
or you can just add system("cls"); in your main function. Note: it requires stdlib.h header file , so don't forget to include it.
或者你可以添加 system("cls"); 在您的主要功能中。注意：它需要 stdlib.h 头文件，所以不要忘记包含它。

open conio.h in "MinGW\include" folder just add these lines at very bottom and save conio.h
在“MinGW\include”文件夹中打开 conio.h 只需在最底部添加这些行并保存 conio.h
#include <stdlib.h>
void clrscr()
{
system("cls");
}
thats all now your clrscr(); will work
这就是你的 clrscr(); 将工作

Try this (It is shorter than the one above):
试试这个（它比上面的短）：
#include <windows.h>
void clrscr()/*Create funcion to clean screen.*/
{
HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
COORD coord = {0, 0};
DWORD count;
CONSOLE_SCREEN_BUFFER_INFO csbi;
GetConsoleScreenBufferInfo(hStdOut, &csbi);
FillConsoleOutputCharacter(hStdOut, ' ', csbi.dwSize.X * csbi.dwSize.Y, coord, &count);
SetConsoleCursorPosition(hStdOut, coord);
}
