function returning String

I'm writing a function that will be called everytime the program ask for the user to input something.

Code:

---

int main(voidz)
{
    char integer[INT_SIZE+EXTRA_SPACES];
    int number;
    printf("Enter a number.");
    *integer=getInput(INT_SIZE);
    number=atoi(integer);
    printf("%i",&integer);


}






void readRestOfLine()
{
  int c;


  /* Read until the end of the line or end-of-file. */
  while ((c = fgetc(stdin)) != '\n' && c != EOF);


  /* Clear the error and end-of-file flags. */
  clearerr(stdin);
}


char* getInput(int size)
{
    char input[size+EXTRA_SPACES];
    fgets(input,size+EXTRA_SPACES,stdin);
    if (input[strlen(input) - 1] != '\n')
    {
        /* String was too long. Reject string and flush input buffer. */
        printf("Input was too long.\n");
        readRestOfLine();
    }
    else
    {
        input[strlen(input) - 1] = '\0';
        return input;
    }
}

My problem is,it's not printing the number entered,but the memory location(i think).And also,when a invalid(over-length) input,it still print out the memory location.
Thanks.

I don't know who taught you to read from a file like that but it's just mental.

On another note "integer" is a char array and you are printing its address. Google how to printf a char array in C.

Also, int main(VOIDZ????) Hahaha.

oops,sorry about the error up there.

Code:

---

int main(void)
{
    char integer[INT_SIZE+EXTRA_SPACES];
    int number;
    printf("Enter a number.");
    *integer=getInput(INT_SIZE);
    number=atoi((void*)integer);
    printf("%s",integer);
    printf("%i",number);


}

why it's not working for the both printf?

number=atoi((void*)integer);

What the hell are you trying to achieve here?

Also, is integer correctly terminated?

You should pass char-Array to your function, you should never return an lokal automatic variable to the calling context, try:

Code:

---

int main(void)
{
    char integer[INT_SIZE+EXTRA_SPACES];
    int number;
    printf("Enter a number.");
    getInput(INT_SIZE+EXTRA_SPACES,integer);
    number=atoi(integer);
    printf("%i",number);
}

void readRestOfLine()
{
  int c;


  /* Read until the end of the line or end-of-file. */
  while ((c = fgetc(stdin)) != '\n' && c != EOF);


  /* Clear the error and end-of-file flags. */
  clearerr(stdin);
}


char* getInput(int size,char *input)
{
    fgets(input,size,stdin);
    if (input[strlen(input) - 1] != '\n')
    {
        /* String was too long. Reject string and flush input buffer. */
        printf("Input was too long.\n");
        readRestOfLine();
    }
    else
    {
        input[strlen(input) - 1] = '\0';
        return input;
    }
}

You should be compiling with warnings enabled. This:

Code:

---

  char input[size+EXTRA_SPACES];

---

is a local variable. You can't return those because they go out of scope when the function ends. Ie, they don't really exist. They may seem to exist, but they are prone to getting overwritten, in whole or in part, by something else (if you used the compiler warnings, you would know this).

thanks~it's working now....^^
