Question

我正在为我的c ++课程制作日历程序，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，都会有不同的颜色）如果不可能，我至少可以大胆一点......

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 << "        ";
            }
            else if (days == 6 || days == 13 || days == 20 || days == 27)
            {

        }

Answer 1

在文本模式下，您有一些限制。但是有一些可移植的库可以处理你的目的，比如着色。

阅读此问题：Portable text based console manipulator并按照link进行操作。它至少可以在（Windows和ANSI-Escape支持的操作系统）之间移植

您可以更改以下代码的颜色：

#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;
}

Answer 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 - 这将允许您的代码可移植到其他系统。或者您可以直接使用ANSI Escape序列[这可能是便携式解决方案在幕后所做的事情，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

请记住，这是不可移植的，并不适用于所有平台。
