turbo c guessing game with do/while loop

I've made a simple program in Turbo C which acts like a guessing game. It should end the game after the user inputs 3 wrong characters, or as soon as the correct one is guessed. However it doesn't work and I can't figure out why. The game just closes after I input 4 characters (wrong or not).

#include <stdio.h>
#include <conio.h>

void main(void)
{
char ch;
int tries = 0;
int win_flag = 0;

clrscr();


printf("Guess the letter: ");

do
{
    ch = getch();
    printf("%c", ch);
    tries++;
    if (ch == 'a')
        win_flag = 1;
    else
        win_flag = 0;
}
while (tries <= 3 || win_flag == 1);

if (tries <= 3)
    printf("\nGame over.");
else if (win_flag == 1)
    printf("\nYou win!");

getch();

}

Solution

  • Change your loop condition as 

    while (tries <= 3 && win_flag == 0);
