我还没有在 C 中找到基本文本颜色的标题，因此我编写了一个标题作为创建彩色 ASCII 字符图表的程序的一部分。使用编译器选项 (/TC) 或默认 C++）和 GCC 在 Visual Studio 2022 中编译时没有错误。该程序包括 AsciiChart.c 和 concolor.h，似乎运行良好。 两者都进行了详尽的评论。 我的问题是，这些文件可以更高效地写入吗？
concolor.h
#ifndef CONCOLOR_H // this is the 'guard' test preventing another header with this name from being overwritten
#define CONCOLOR_H // if there is no other header by this name then define it
/*
The following 'defines' connect each ANSI code string with a readable name.
To use these color/styles just enter the capitalized word in your 'printf' statements
positioned AFTER the formatting string and before the literal strings or variables
followed by a comma (examples in the 'asciichart.c' file).
Remember to add an additional '%s' in the formatting string as a place holder for the color string.
There are ways of shrinking this file to arrays and/or pointers but this is easier to understand.

/* This program will display an ascii chart in the command window
for each corresponding decimal, hex, and octal number.
The first page is the standard ascii set, the second is the extended set.
The pages will toggle back and forth with ANY key press until the command window is closed.
If you right click the top of the cmd window and select 'settings' then
select 'launch size' and set columns to 120 and rows to 36 and run again it will fit better.
This program compiled without errors or warnings in Visual Studio 2022 using the 'C Code (/TC)' compiler.
To build this program make sure both this file and 'concolor.h' are in the same directory and compile it
adding both file names to the compiler input string and a file name(.exe) of your choice for the output
string if you are using a command line compiler like GCC.

我见过的大多数示例都显示在 printf 函数语句的格式化部分插入 color 关键字。 这对于 Visual Studio 中的 C++ 编译器来说没有问题，但当使用 GCC 编译时，它只在各处打印转义序列文本，而没有任何颜色更改。 这已在这些文件中得到纠正。
我们并不期望每个答案都是完美的，但拼写、标点符号和语法正确的答案更容易阅读。他们也往往更频繁地获得支持。请记住，您可以随时返回并编辑您的答案以改进它。
