Do while help please

Im making a do while loop for C and the part I'm having trouble with looks like this

Code:

---

char y;

do
        {
        printf("On this machine the number of bytes in a char is : %d\n", sizeof(char));

        printf("On this machine the number of bytes in a short is : %d\n", sizeof(short));

        printf("On this machine the number of bytes in a int is : %d\n", sizeof(int));

        printf("On this machine the number of bytes in a long is : %d\n", sizeof(long));

        printf("On this machine the number of bytes in a float is : %d\n", sizeof(float));

        printf("On this machine the number of bytes in a double is : %d\n", sizeof(double));

        printf("On this machine the number of bytes in a pointer is : %d\n", sizeof(char));

        printf("On this machine the number of bytes in a struct is : %d\n", sizeof(struct student));

        printf("Would you like to see the information again?\n");



y = getchar();

}

while (scanf("%s",&y));

while (y == 'y');

while (y != EOF);


}

Well im new to this programming stuff, but im suppose to make a program that displays all those "On this machine" quotes everytime the user enters the letter "y". And if the user enters anything else, the program is suppose to print out : "Goodbye" and exit the program. The problem is that whenever i execute and enter "y", it prints out "on this machine", which is what I want. But i dont know how to get it to print "goodbye" and exit.

If anyone could help me, I will love you long time. :D

/* Your do-while is officially over. */

while (y == 'y'); /* while y is 'y', do nothing at all, indefinately */
/* Your plain old 'while' loop is over, if at all possible. */

while (y != EOF);  /* See above, except test for EOF, except you can't. */
/* Your THIRD loop is now over. */


}

The EOF FAQ will tell you why it's wrong to use a char to test for EOF.

Keep the love for someone who wants it.


Quzah.

when you say my do while loop is over, do you mean it wont loop anymore?

Ermm, is it just me, or is this thread somehow familiar to this one?

I Love You!!!

> or is this thread somehow familiar to
Well both posters are from the same school, so I guess they're both in the same class as well.

Code:

---

int y = 0;

do
{
  /* statements */
  y = getchar();
} while (y == 'y' || y == 'Y');

Something similair to this is what you want.
