Thread: looping went berserk

Could anyone advice me on why my loop gives a funny output?

My program should work this way...
1. Prompt user if they want to play the game
2. If user type 'y'
>>>2.1. Display 3 random number
>>>2.2. Prompt user if they want to play again.
>>>2.3. If user type 'y' again (repeat step 2.1 & 2.3)
>>>2.4. Else If user type 'n', program terminate.
3. Else if user type 'n', no loop just terminate program.

Here is my code...

Code:

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

void welcome_msg(void)
{
  printf("Pick your number! \n");
}

void reply_msg(char reply)
{
  printf("Would you like to play? (y/n) ");
  scanf("%c", &reply);
}

void num_display(void)
{
  srand((unsigned)time(NULL));
  printf("\nNum: %i  %i  %i  ", rand() %10, rand() %10, rand() %10);
}

void goodbye_msg(void)
{
  printf("Thank you for playing.\n");
}

int main(void)
{
  char answer;

  welcome_msg();
  reply_msg(answer);

  looping: /* a label */
  printf("Play again? \n ");
  scanf("%c", &answer);
  
  if(answer == 'n')
  {
    goodbye_msg();
  }
  else
 {
   num_display();
   goto looping; /* Jump to the label*/
  }

 return 0;
}

Really appreciate for all the help.
Thanks in advance!

also

Code:

void reply_msg(char reply)

is not returning the value of answer
this code is messy

Okie now I'm a little confused which to change first....

Well I'm trying to change the getchar... but not sure where I've to put it in my code without the go to...

Here is what I've done without the "go to"

Code:

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

void welcome_msg(void)
{
 printf("Pick your number!\n");
}

void num_display(void)
{
 srand((unsigned)time(NULL));
 printf("Num: %i  %i  %i  ", rand() %10, rand() %10, rand() %10);
}

void goodbye_msg(void)
{
 printf("Thank you for playing.\n");
}

int main(void)

{
 char ans;
 char ch;

 welcome_msg();
 puts("Would you like to play (yes/no)? ");

 while((ch = getchar()) != '\n' && ch != EOF);
  if (ans == 'y')
 {
  num_display();
  printf("Play again? ");
  scanf("%c", &ans);
 }
 else
 if (ans == 'n')
 {
  goodbye_msg();
}

return(0);
}

I know the code don't make any sense... but oh boy... im getting real confused.... any help would be great!

Like this:

Code:

    while (c != '\n' && c != EOF && c != 'n') {
        c = getchar();
        scanf("%c", &input);
        if (input != 'n')
            printf("%d %d %d\n", rand() % 10, rand() % 10, rand() % 10);
    }
