Can someone help me if possible?

I have wrote a program to guess a randomly generated number correctly within 3 goes.


Nearly cracked it, just one final thing I noticed when I was debugging, if I put 2 wrong answers in, then enter the right answer on the third go, it will tell me I have had too many goes and kick me out, but if I increase the count condition by one, it keeps telling me that my third answer is always correct, even if it isn't.

I have already tried moving the increment value to outside the loop, but obviously after the first loop, the value will not change.

Could someone have a look and see if it can be rectified or suggest any ideas?

Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>

// Guess a number 1-6 with 3 tries

void main()
{
	int a, ans;
	int count = 0;

	srand((unsigned) time (NULL));
	
	ans = ((rand()%6)+1);
	printf("%d\n", ans);
	printf("Three chances to to guess a number between 1 - 6: ");
	scanf("%d", &a);
		
	while ((a != ans) && (count < 2))
	{
		count++;
		printf("Wrong! Please try again: Number of goes so far (%d): ", count +1);
		scanf("%d", &a);

	}

	if (count >=2 )
	{
		printf("Too many goes. End of game. The number was %d\n", ans);
	}
	else
	{
		printf("Correct!\n");
		printf("You had %d goes.\n", count + 1);
	}
}

I am interested in your matter. Now I am stuck with my assignments. I will send a corrected version as the reply tomorrow. With a rough look I saw that the loop condition
while((a != ans) && (count < 2)) should be corrected to
while((a != ans) && (count < 3)). Starting the counter from 1 will also avoide conflicts unless you are familiyar with the concepts of programming. As a suggestion you should use a for loop so the conflicts are minimum. As a matter of style, I think you should use a bool type value to check the condition. To keep portability, do not use void as the return type of main().

Code:
# include <stdio.h>
# include <stdlib.h>
# include <time.h>

int main(void)
{
  int ans, val, ctr;
  srand((unsigned) time(NULL));
  val = (rand() % 6) + 1;
  ans = 0;
  ctr = 0;
  while(ans != val && ctr < 3)
  {
    printf("Enter a value between 1 and 6  :  ");
    fflush(stdin);
    scanf("%d", &ans);
    puts("");
    ctr++;
  }
  if(ans == val)
  {
    printf("You Guessed correct in %d guesses!\n", ctr);
  }
  else
  {
    printf("Too Many Guesses!!!\n");
  }
  fflush(stdin);
  getchar();
  return 0;
}
