Visual C ++ Win32控制台应用程序printf在while循环内的多行输出

Question

I am trying to display data on multiple lines in my console application using printf. The following code displays the data like this:

Default Data=00000000 ACP Status Request=00000000 ACP VHF1 Data=00000000

What I need is:

Default Data=00000000

ACP Status Request=00000000

ACP VHF1 Data=00000000

When I use \\n the data fills the console screen over and over again. Can anyone suggest a solution and explain why the loop is fine and the code works untill I try and goto the next line. Thanks.

while(!_kbhit())
{
    /*Read message records*/
    msgdefault.data = BTI429_MsgDataRd(msgdefault.addr,hCore);

    STAT_REQ.data = BTI429_MsgDataRd(STAT_REQ.addr,hCore);

    VHF1.data   = BTI429_MsgDataRd(VHF1.addr,hCore);

    /*Display values*/
    printf("\r");
    printf("Default Data=%08lX ",msgdefault.data);
    //printf("\n");
    printf("ACP Status Request=%08lX ",STAT_REQ.data);
    //printf("\n");
    printf("ACP VHF1 Data=%08lX ",VHF1.data);
}

You need some function to jump to the start of your screen.

Read your documentation, there may be some function like gotoxy(0,0) or something else.

Try searching for System::Console::SetCursorPosition , this may help you.

Try adding following code in the start of loop before printing anything

HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);

_COORD p;
p.X = x;
p.Y = y;

SetConsoleCursorPosition(hConsole, p);

But make sure to print some empty spaces after your prints so that the remains of old prints are overwritten.
