Enter Password in C

Question

I am aware that it is not possible to echo the * while you type in standard ANSI C. But is there a way to display nothing while someone is typing their password in the conso

Answer 1

*This is not ANSI C (Thanks Billy) sample

You can detect keypress with _kbhit(), then get the value using _getch(). Both function will not echo the content on screen.

#include           //For keyboard events
#include           //Include this or iostream
#include            
int main()
{
    bool bContinue = true;
    char szBuffer[255] = {0};
    unsigned int nbufIndex = 0;
    while (bContinue)
    {
        if (_kbhit())
        {
            szBuffer[nbufIndex] = _getch();
            if (szBuffer[nbufIndex] == 0xD)
            {
                bContinue = false;
            }
            else
            {
                ++nbufIndex;
                printf("*");
            }
        }
    }
    printf("\n%s\n", szBuffer);
    return 0;
}
