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时:: blocks会给我一个错误 - 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。编译器给出了相同的错误,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。
即使答案是在C ++中,我也没关系。

textcolor 等函数在旧编译器中工作,如 turbo C 和 Dev C 。 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,我正在参加您的示例程序 -
#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;
}
运行程序时,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
现在我将提供 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, 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,因为白色的代码为15.这对我来说是代码:: blocks。希望它也适合你。

您还可以使用rlutil:
rlutil.h
),setColor()
,cls()
,getch()
,gotoxy()
等。您的代码会变成这样:
#include <stdio.h>
#include "rlutil.h"
int main(int argc, char* argv[])
{
setColor(BLUE);
printf("\n \n \t This is dummy program for text color ");
getch();
return 0;
}

我知道,我来晚了,但也许我的回答可以帮助某人。 基本上,这很简单。 这是我的代码。
#include<iostream>
#include<windows.h>
using namespace std;
int main()
{
HANDLE colors=GetStdHandle(STD_OUTPUT_HANDLE);
string text;
int k;
cout<<" Enter your Text : ";
getline(cin,text);
for(int i=0;i<text.length();i++)
{
k>9 ? k=0 : k++;
if(k==0)
{
SetConsoleTextAttribute(colors,1);
}else
{
SetConsoleTextAttribute(colors,k);
}
cout<<text.at(i);
}
}
输出

这是一个在线功能,我用它创建了一个头文件,我使用Setcolor();
代替,我希望这有帮助!您可以通过选择0-256范围内的任何颜色来更改颜色。 :)可悲的是,我相信CodeBlocks后来构建了window.h库...
#include <windows.h> //This is the header file for windows.
#include <stdio.h> //C standard library header file
void SetColor(int ForgC);
int main()
{
printf("Test color"); //Here the text color is white
SetColor(30); //Function call to change the text color
printf("Test color"); //Now the text color is green
return 0;
}
void SetColor(int ForgC)
{
WORD wColor;
//This handle is needed to get the current background attribute
HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
CONSOLE_SCREEN_BUFFER_INFO csbi;
//csbi is used for wAttributes word
if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
{
//To mask out all but the background attribute, and to add the color
wColor = (csbi.wAttributes & 0xF0) + (ForgC & 0x0F);
SetConsoleTextAttribute(hStdOut, wColor);
}
return;
}
答案 4 :(得分:1)
textcolor
函数。
这是更改代码块中文本颜色的最简单方法。
您可以使用system
函数。
更改文本颜色:
#include<stdio.h>
#include<stdlib.h> //as system function is in the standard library
int main()
{
system("color 1"); //here 1 represents the text color
printf("This is dummy program for text color");
return 0;
}
如果要同时更改文本颜色和控制台颜色,只需在system
函数中添加其他颜色代码
更改文本颜色和控制台颜色:
system("color 41"); //here 4 represents the console color and 1 represents the text color
N.B:请勿在这样的颜色代码之间使用空格
system("color 4 1");
尽管如此,“代码块”将显示所有颜色代码。您可以使用此技巧来了解所有受支持的颜色代码。

一种简单的方法......
system("Color F0");
Letter代表背景颜色,而数字代表文字颜色。
0 =黑色
1 =蓝色
2 =绿色
3 = Aqua
4 =红色
5 =紫色
6 =黄色
7 =白色
8 =灰色
9 =淡蓝色
A =浅绿色
B = Light Aqua
C =浅红色
D =浅紫色
E =浅黄色
F =亮白色
答案 6 :(得分:0)
system("COLOR 0A");

其中0A是背景和字体颜色的组合 0
答案 7 :(得分:-1)
您应该先定义函数textcolor。因为textcolor不是C中的标准函数。
void textcolor(unsigned short color) {
HANDLE hcon = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hcon,color);
}
