更改數組中元素的文本顏色

Question

我有一個程序打印出數組中冒泡排序的通行證，並且想要嘗試添加顯示（通過文本顏色更改）在哪裏進行交換的功能每次傳遞數組。到目前爲止，我嘗試過的所有內容都會更改所有文本顏色，或者不會更改任何內容（如當前示例所示）。有人有主意嗎？

#include <iostream> 
#include <Windows.h> 
#include <iomanip> 
#include <string> 

using namespace std; 

void sortArrayAscending(int *array, int size); 
void printArray(int *array, int); 
void printUnsortedArray(int *array, int size); 

int main() 
{ 
HANDLE a = GetStdHandle(STD_OUTPUT_HANDLE); 
SetConsoleTextAttribute(a, FOREGROUND_GREEN | FOREGROUND_INTENSITY); 

HANDLE screen = GetStdHandle(STD_OUTPUT_HANDLE); 

string hyphen; 
const string progTitle = "Array Sorting Program"; 
const int numHyphens = 100; 

hyphen.assign(numHyphens, '-'); 

const int size = 8; 

int values[size] = { 21, 16, 23, 18, 17, 22, 20, 19 }; 

cout << hyphen << endl; 
cout << "  " << progTitle << endl; 
cout << hyphen << endl; 

cout << "\n This program will sort two identical arrays of numbers using a Bubble Sort"<< endl; 


cout << "\n Array 1 -- Ascending Order: \n" << endl; 

printUnsortedArray(values, size); 

cout << endl; 
sortArrayAscending(values, size); 

cin.ignore(cin.rdbuf()->in_avail()); 
cout << "\n\n\n\nPress only the 'Enter' key to exit program: "; 
cin.get(); 
} 

void sortArrayAscending(int *array, int size) 
{ 
const int regTextColor = 2; 
const int swapTextColorChange = 4; 

HANDLE screen = GetStdHandle(STD_OUTPUT_HANDLE); 

int temp; 
bool swapTookPlace; 
int pass = 0; 

do 
{ 
    swapTookPlace = false; 
    for (int count = 0; count < (size - 1); count++) 
    { 

     if (array[count] > array[count + 1]) 
     { 

      swapTookPlace = true; 
      temp = array[count]; 
      array[count] = array[count + 1]; 
      array[count + 1] = temp; 


      if (swapTookPlace) 
      { 
       SetConsoleTextAttribute(screen, FOREGROUND_GREEN | FOREGROUND_INTENSITY); 

       if (array[count] > array[count + 1]) 
       { 
        SetConsoleTextAttribute(screen, swapTextColorChange); 
       } 
       if (pass < 9) 
       { 
        cout << fixed << setw(2) << " Pass # " << (pass + 1) << " : "; 
        pass += 1; 
        printArray(&array[0], size); 
       } 
       else if (pass >= 9) 
       { 
        cout << fixed << setw(2) << " Pass # " << (pass + 1) << " : "; 
        pass += 1; 
        printArray(&array[0], size); 
       } 
      } 
     } 
    } 
} while (swapTookPlace); 
} 

void printArray(int *array, int size) 
{ 
for (int count = 0; count < size; ++count) 
    cout << "  " << array[count] << " "; 
cout << endl; 
} 

void printUnsortedArray(int *array, int size) 
{ 
cout << " Unsorted "; 
for (int count = 0; count < size; ++count) 
    cout << "  " << array[count] << " "; 
cout << endl;

您需要有一個基本的顏色，當沒有任何交換（白色）時，您想使用。你從那種顏色開始。然後保存當前的屬性設置：

HANDLE handle = GetStdHandle(STD_OUTPUT_HANDLE); 
CONSOLE_SCREEN_BUFFER_INFO Info; 
WORD defaultAttributes = 0; 
GetConsoleScreenBufferInfo(handle, &Info); 
defaultAttributes = Info.wAttributes;

然後改變顏色，您的交換顏色，當你想顯示交換（如你已經這樣做），並重新設置默認的屬性時有沒有交換：

SetConsoleTextAttribute(handle, defaultAttributes);

這裏是個e解決方案。

使用-std = C++ 11標誌在g ++ 5.1.0上編譯。

從Windows的cmd.exe
