     NAME
          itoa - convert an integer to an ASCII character string

     SYNOPSIS
          int num;
          char *itoa(int, char *), string;
          ...
          itoa(num, string);

          num     Value of type int
          string  A byte pointer to a character array

     DESCRIPTION
          The itoa function converts an integer to an ASCII string.
          If num is negative, the string will contain a minus sign,
          one to 10 digits, and a null.

          The include file stdio.h defines this function.  It also
          defines a macro Litoa, which is replaced by 13, the maximum
          number of characters itoa returns.

     RETURN VALUE
          Address The address of the string returned

     EXAMPLE
          #include <stdio.h>
          #define STRINGMIN 13

          int i = 1, num;
          char string[STRINGMIN], *itoa(int, char *);

          main(argc, argv)
          int argc;
          char *argv[];
          {
               while (i < argc) {
                    num = atoi(argv[i]);
                    num *= i;
                    itoa(num, string);
                    printf("%s0, string);
                    i++;
               }
               return 0;
          }

          A call to the program test with the numbers 1, 2, 3, and 4
          generates the output
