c++ - 如何更改 code::blocks 中的文本颜色和控制台颜色？

Question

我正在用 C 编写程序。我想在控制台中更改文本颜色和背景颜色。我的示例程序是 -

#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
#include <dos.h>
#include <dir.h>

int main(int argc,char *argv[])
{
 textcolor(25);
 printf("\n \n \t This is dummy program for text color ");
 getch();

 return 0;
}

当我编译这个程序时，code::blocks 给我一个错误 - textcolor not defined。为什么会这样？我在 GNU GCC 编译器和 Windows Vista 中工作。如果它不起作用，文本颜色的拷贝是什么。就像那样我想改变控制台的背景颜色。编译器给我同样的错误只是函数的名称不同。如何更改控制台和文本的颜色。请帮忙。

即使答案是用 C++ 我也可以。

Answer 1

textcolor 等函数可在 turbo C 和 Dev C 等旧编译器中使用。在今天的编译器中，这些函数将不起作用。我将提供两个函数 SetColor 和 ChangeConsoleToColors。您将这些函数代码复制粘贴到您的程序中，然后执行以下步骤。我提供的代码在某些编译器中将无法运行。

SetColor 的代码是 -

 void SetColor(int ForgC)
 {
     WORD wColor;

      HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
      CONSOLE_SCREEN_BUFFER_INFO csbi;

                       //We use csbi for the wAttributes word.
     if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
     {
                 //Mask out all but the background attribute, and add in the forgournd     color
          wColor = (csbi.wAttributes & 0xF0) + (ForgC & 0x0F);
          SetConsoleTextAttribute(hStdOut, wColor);
     }
     return;
 }

要使用此函数，您需要从您的程序中调用它。例如，我正在使用您的示例程序 -

#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
#include <dos.h>
#include <dir.h>

int main(void)
{
  SetColor(4);
  printf("\n \n \t This text is written in Red Color \n ");
  getch();
  return 0;
}

void SetColor(int ForgC)
 {
 WORD wColor;

  HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
  CONSOLE_SCREEN_BUFFER_INFO csbi;

                       //We use csbi for the wAttributes word.
 if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
 {
                 //Mask out all but the background attribute, and add in the forgournd color
      wColor = (csbi.wAttributes & 0xF0) + (ForgC & 0x0F);
      SetConsoleTextAttribute(hStdOut, wColor);
 }
 return;
}

当您运行该程序时，您将获得红色的文本颜色。现在我要给你每种颜色的代码 -

Name         | Value
             |
Black        |   0
Blue         |   1
Green        |   2
Cyan         |   3
Red          |   4
Magenta      |   5
Brown        |   6
Light Gray   |   7
Dark Gray    |   8
Light Blue   |   9
Light Green  |   10
Light Cyan   |   11
Light Red    |   12
Light Magenta|   13
Yellow       |   14
White        |   15

现在我要给出ChangeConsoleToColors的代码。代码是——

void ClearConsoleToColors(int ForgC, int BackC)
 {
 WORD wColor = ((BackC & 0x0F) << 4) + (ForgC & 0x0F);
               //Get the handle to the current output buffer...
 HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
                     //This is used to reset the carat/cursor to the top left.
 COORD coord = {0, 0};
                  //A return value... indicating how many chars were written
                    //   not used but we need to capture this since it will be
                      //   written anyway (passing NULL causes an access violation).
  DWORD count;

                               //This is a structure containing all of the console info
                      // it is used here to find the size of the console.
 CONSOLE_SCREEN_BUFFER_INFO csbi;
                 //Here we will set the current color
 SetConsoleTextAttribute(hStdOut, wColor);
 if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
 {
                          //This fills the buffer with a given character (in this case 32=space).
      FillConsoleOutputCharacter(hStdOut, (TCHAR) 32, csbi.dwSize.X * csbi.dwSize.Y, coord, &count);

      FillConsoleOutputAttribute(hStdOut, csbi.wAttributes, csbi.dwSize.X * csbi.dwSize.Y, coord, &count );
                          //This will set our cursor position for the next print statement.
      SetConsoleCursorPosition(hStdOut, coord);
 }
 return;
}

在此函数中，您传递两个数字。如果你想要正常的颜色，只需将第一个数字作为零，将第二个数字作为颜色。我的例子是 -

#include <windows.h>          //header file for windows
#include <stdio.h>

void ClearConsoleToColors(int ForgC, int BackC);

int main()
{
ClearConsoleToColors(0,15);
Sleep(1000);
return 0;
}
void ClearConsoleToColors(int ForgC, int BackC)
{
 WORD wColor = ((BackC & 0x0F) << 4) + (ForgC & 0x0F);
               //Get the handle to the current output buffer...
 HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
                     //This is used to reset the carat/cursor to the top left.
 COORD coord = {0, 0};
                  //A return value... indicating how many chars were written
                    //   not used but we need to capture this since it will be
                      //   written anyway (passing NULL causes an access violation).
 DWORD count;

                               //This is a structure containing all of the console info
                      // it is used here to find the size of the console.
 CONSOLE_SCREEN_BUFFER_INFO csbi;
                 //Here we will set the current color
 SetConsoleTextAttribute(hStdOut, wColor);
 if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
 {
                          //This fills the buffer with a given character (in this case 32=space).
      FillConsoleOutputCharacter(hStdOut, (TCHAR) 32, csbi.dwSize.X * csbi.dwSize.Y, coord, &count);

      FillConsoleOutputAttribute(hStdOut, csbi.wAttributes, csbi.dwSize.X * csbi.dwSize.Y, coord, &count );
                          //This will set our cursor position for the next print statement.
      SetConsoleCursorPosition(hStdOut, coord);
 }
 return;
} 

在这种情况下，我将第一个数字设置为零，将第二个数字设置为 15，因此控制台颜色将为白色，因为白色代码为 15。这在 code::blocks 中对我有用。希望它也对你有用。
