【问题描述】：

我正在为我的 c++ 课程制作一个日历程序，我只是想知道是否有办法改变程序中某些日子的颜色（例如，圣诞节、新年、周末，都会是不同的颜色）如果不可能，我至少可以加粗或其他什么...

这是我的代码

char *month_name[12] = {"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"};
char *month_underline[12] = {"-------", "--------", "-----", "-----", "---", "----", "----", "------", "---------", "-------", "--------", "--------"};
char *week_name[7] = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};
int days = 1;
int days_max;
int i, j, k;

for(i = 0; i < 12; i++)
{
    cout << "--------------------------------------------------------------------------------";

    cout << '\n' << month_name[i] << '\n';
    cout << month_underline[i] << "\n\n";

    for (j = 0; j < 7; j++)
    {
        cout << week_name[j] << "     ";
    }



    cout << "\n\n";

    if (i == 0 || i == 2 || i == 4 || i == 6 || i == 7 || i == 9 || i == 11) //i is the number of the month minus 1 (jan = 0, feb = 1, etc.)
        days_max = 32;
    else if (i == 3 || i == 5 || i == 8 || i == 10)
        days_max = 31;
    else if (i == 1)
        days_max = 29;

    for (days = 1; days < days_max; days++)
    {
        if (i == 0 || i == 9)
        {
            if (days == 1)
            {
                cout << "                        ";
                cout << setw(4) << days << "        ";
            }

【问题讨论】：

哪个操作系统？在 Windows 中，SetConsoleTextAttribute。
system("PAUSE") 看起来像是一种奇怪的暂停程序的方式...

标签： c++ colors

【解决方案1】：

在文本模式下，您有一些限制。但是有一些便携式库可以处理您的目的，例如着色。

阅读这个问题：Portable text based console manipulator 并关注link。它至少在（支持 Windows 和 ANSI-Escape 的操作系统）之间是可移植的

你可以像下面的代码改变颜色：

#include <iostream>
#include "rlutil.h"  // <-- Get it from the link
int main()
{
    rlutil::setColor(2); // 2 for Green

    std::cout << "Hello! I am green!" << std::endl;

    return 0;
}

【解决方案2】：

没有 C++“标准”方法可以做到这一点。您可以按照 Masoud 的建议找到一个库 - 这将使您的代码可以移植到其他系统。或者您可以直接使用例如 ANSI Escape 序列[这可能是便携式解决方案在幕后所做的，但还有其他方法]。

此页面提供了一些信息： http://en.wikipedia.org/wiki/ANSI_escape_code

但请记住，这是不可移植的，并且不适用于所有平台。
