  NAME
  ****
  ft_isascii ---> is a ascii character

  SYNOPSIS
  ***********
  #include <ctype.h>
  int	isascii(int c);
  #include "libft.h"
  int	ft_isascii(int c);

  DESCRIPTION
  ***********
  The function ft_isascii() mimics the behavior of the isascii() function from
  ctype C library. Both functions check if c is a 7-bit unsigned char value
  that fits into the ASCII character set.

  PARAMETERS
  **********
  c ---> The character to be checked.

  RETURN VALUE
  ************
  - Non-zero value if c is a digit or a letter.
  - Zero value if not.

  NOTES	
  *****
  isascii() is a BSD extension and is also an SVr4 extension.
  POSIX.1-2008 marks isascii() as obsolete, noting that it cannot be used portably
  in a localized application.

/*
  RETURN A CONDITION
  ******************
  When we return a condition, the computer will check if the condition is true or
  false. If it is true it will return 1(boolean true) and if it is false it will
  return 0(boolean false).
