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;
- }
当我编译这个程序代码:: blocks给我一个错误 – textcolor未定义.为什么会这样?我在GNU GCC编译器和Windows Vista中工作.如果它不起作用什么是textcolor的副本.就像我想要改变控制台的背景颜色.只要函数名称不同,编译器就会给出同样的错误.如何更改控制台和文本的颜色.请帮忙.
即使答案是在C中,我也没关系.
解决方法
像textcolor这样的函数在turbo C和Dev C等旧编译器中运行.
在今天的编译器中,这些功能不起作用.我将提供两个函数SetColor和ChangeConsoleToColors.您将这些函数代码复制粘贴到程序中并执行以下步骤.我给出的代码在某些编译器中不起作用.

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;
- }
要使用此功能,您需要从程序中调用它.例如我正在拿你的示例程序 –
- #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;
- }
运行程序时,您将获得RED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,&count );
- //This will set our cursor position for the next print statement.
- SetConsoleCursorPosition(hStdOut,coord);
- }
- return;
- }
在此功能中,您传递两个数字.如果你想要正常颜色,只需将第一个数字设为零,将第二个数字设为颜色即可.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,coord);
- }
- return;
- }
在这种情况下,我将第一个数字设置为零,第二个数字设置为15,因此控制台颜色将为白色,因为白色的代码为15.这对我来说是代码:: blocks.希望它也适合你.
