How to change text color and console color in code::blocks?
提问by Ashish Ahuja
I am writing a program in C. I want to change the text color and background color in the console. My sample program is -
我正在用 C 编写程序。我想更改控制台中的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;
}
When I compile this program code::blocks gives me an error - textcolor not defined. Why is this so? I work in a GNU GCC compiler and Windows Vista. If it is not going to work what is the duplicate of textcolor. Like that I want to change the background color of the console. The compiler gives me the same error just the name of the function is different. How to change the color of the console and text. Please help.
当我编译这个程序 code::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，textcolor 的副本是什么。就像那样，我想更改控制台的背景颜色。编译器给了我同样的错误，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。
I am okay even if the answer is in C++.
即使答案是在 C++ 中，我也没关系。

Functions like textcolorworked in old compilers like turbo Cand Dev C. In today's compilers these functions would not work. I am going to give two function SetColorand ChangeConsoleToColors. You copy paste these functions code in your program and do the following steps.The code I am giving will not work in some compilers.
像textcolor这样的函数可以在像turbo C和Dev C这样的旧编译器中工作。在今天的编译器中，这些函数不起作用。我将给出两个函数SetColor和ChangeConsoleToColors。您将这些函数代码复制粘贴到您的程序中并执行以下步骤。我提供的代码在某些编译器中不起作用。
The code of SetColoris -
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;
}
To use this function you need to call it from your program. For example I am taking your sample program -
要使用此功能，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;
}
When you run the program you will get the text color in RED. Now I am going to give you the code of each color -
当您运行程序时，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
Now I am going to give the code of ChangeConsoleToColors. The code is -
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;
}
In this function you pass two numbers. If you want normal colors just put the first number as zero and the second number as the color. My example is -
在此函数中，您传递两个数字。如果您想要正常颜色，只需将第一个数字设为零，将第二个数字设为颜色。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;
}
In this case I have put the first number as zero and the second number as 15 so the console color will be white as the code for white is 15. This is working for me in code::blocks. Hope it works for you too.
在这种情况下，我将第一个数字设为 0，将第二个数字设为 15，因此控制台颜色将为白色，因为白色的代码是 15。这在 code::blocks 中对我有用。希望它也适用于你。

You can also use rlutil:
您还可以使用rlutil：
- cross platform,
- header only (
rlutil.h), - works for C and C++,
- implements
setColor(),cls(),getch(),gotoxy(), etc. - License: WTFPL
- 跨平台，
- 仅标题 (
rlutil.h), - 适用于 C 和 C++，
- 农具
setColor()，cls()，getch()，gotoxy()，等。 - 执照：WTFPL
Your code would become something like this:
你的代码会变成这样：
#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;
}

This is a function online, I created a header file with it, and I use Setcolor();instead, I hope this helped! You can change the color by choosing any color in the range of 0-256. :) Sadly, I believe CodeBlocks has a later build of the window.h library...
这是一个在线功能，我用它创建了一个头文件，我用它Setcolor();来代替，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 有一个更高版本的 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;
}

textcolorfunction is no longer supported in the latest compilers.
textcolor最新的编译器不再支持该函数。
This the simplest way to change text color in Code Blocks.
You can use systemfunction.
这是在代码块中更改文本颜色的最简单方法。您可以使用system功能。
To change Text Color :
要更改文本颜色：
#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;
}
If you want to change both the text color & console color you just need to add another color code in systemfunction
如果您想同时更改文本颜色和控制台颜色，您只需要在system函数中添加另一个颜色代码
To change Text Color & Console Color :
要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: Don't use spaces between color code like these
注意：不要在这些颜色代码之间使用空格
system("color 4 1");
Though if you do it Code Block will show all the color codes. You can use this tricks to know all supported color codes.
但是，如果您这样做，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支持的颜色代码。

You should define the function textcolor before. Because textcolor is not a standard function in C.
您应该之前定义函数 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);
}
