ex_ctype.nxc

This is an example of how to use the ctype API functions: isupper, islower, isalpha, isdigit, isalnum, isspace, iscntrl, isprint, isgraph, ispunct, isxdigit, toupper, and tolower.

task main()
{
  string tmp = "a1B2.G% ";
  TextOut(0, LCD_LINE1, tmp);
  NumOut(0, LCD_LINE2, isalnum(tmp[0])); // 1
  NumOut(0, LCD_LINE3, isalpha(tmp[1])); // 0
  NumOut(0, LCD_LINE4, iscntrl(tmp[2])); // 0
  NumOut(0, LCD_LINE5, isdigit(tmp[3])); // 1
  NumOut(0, LCD_LINE6, isgraph(tmp[4])); // 1
  NumOut(0, LCD_LINE7, islower(tmp[5])); // 0
  NumOut(0, LCD_LINE8, isprint(tmp[6])); // 1

  NumOut(40, LCD_LINE2, ispunct(tmp[0])); // 0
  NumOut(40, LCD_LINE3, isspace(tmp[1])); // 0
  NumOut(40, LCD_LINE4, isupper(tmp[2])); // 1
  NumOut(40, LCD_LINE5, isxdigit(tmp[3])); // 1
  NumOut(40, LCD_LINE6, tolower(tmp[4])); // 46
  NumOut(40, LCD_LINE7, toupper(tmp[5])); // 71

  Wait(SEC_5);
