如何在c ++

Question

//跟随代码一旦改变颜色，然后他们一直保持它们，//如果我想用不同的颜色写一个单词，如cout＆lt;＆lt;“4June”//应该用红色的jxt文本的颜色应该改变不是背景//颜色，如果我显示的东西像cout＆lt;＆lt;“颜色没有改变”;那么//颜色应该是原始颜色，如何获得那个c ++ ????

#include <iostream>
#include <windows.h>
#include <winnt.h>
#include <stdio.h>
#include "stdafx.h"
using namespace std;

int main(int argc, char* argv[])
{
   HANDLE consolehwnd = GetStdHandle(STD_OUTPUT_HANDLE);
   cout << "this text is not colorized\n";
   SetConsoleTextAttribute(consolehwnd, FOREGROUND_RED);
   cout << "this text shows as red\n";
   SetConsoleTextAttribute(consolehwnd, FOREGROUND_BLUE);
   cout << "this text shows as blue\n";
}


OR

SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),1)

OR

system("color 3");
cout<<"colour changed"<<endl;**

Answer 1

如果您希望将red文字投放到black背景，则只需输入SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),4); cout<<"4th June";

要重置为正常颜色，请将其设置为颜色7。 SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),7);

以下是所有控制台颜色的表格。只需输入上图中的颜色代码编号即可制作256种组合，以获得所需的颜色。

以下是一些控制台颜色管理代码。

#include <windows.h> 
#include <iostream>
using namespace std;




void gotoxy(int x, int y);
void setcolor(WORD color);
void setForeGroundAndBackGroundColor(int ForeGroundColor,int BackGroundColor);
void clrscr(); 
void printAllColors();



int main()
{
  // set red text on black background    
  gotoxy(30,10);
  SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),4); cout<<"4th June";  

  // set white text on black background
  gotoxy(1,23);
  SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),7);



  return 0;
}


void setcolor(WORD color)
{
    SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),color);
    return;
}



void setForeGroundAndBackGroundColor(int ForeGroundColor,int BackGroundColor)
{
   int color=16*BackGroundColor+ForeGroundColor;
   setcolor(color);
}




void gotoxy(int x, int y)
{
    COORD coord;
    coord.X = x; coord.Y = y;
    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord);
    return;
}




void clrscr()
{
    COORD coordScreen = { 0, 0 };
    DWORD cCharsWritten;
    CONSOLE_SCREEN_BUFFER_INFO csbi;
    DWORD dwConSize;
    HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);

    GetConsoleScreenBufferInfo(hConsole, &csbi);
    dwConSize = csbi.dwSize.X * csbi.dwSize.Y;
    FillConsoleOutputCharacter(hConsole, TEXT(' '), dwConSize, coordScreen, &cCharsWritten);
    GetConsoleScreenBufferInfo(hConsole, &csbi);
    FillConsoleOutputAttribute(hConsole, csbi.wAttributes, dwConSize, coordScreen, &cCharsWritten);
    SetConsoleCursorPosition(hConsole, coordScreen);
    return;
}


void printAllColors()
{
   int ix=0;
   int iy=1;
   int col=0;
   setcolor(7);
   clrscr();

   // Demo setForeGroundAndBackGroundColor
   for (int i =0;i<16;i++)
   {
      for(int j=0;j<16;j++)
      {
       setForeGroundAndBackGroundColor(i,j);
       gotoxy(i*5  , iy+j); cout<<""<<i + (16 *j)<<"";
       col++;
      }
   }


   setcolor(31);
   cout<<"\n";

  gotoxy(1,23);
}
