ASCII is a 7-bit code, meaning that 128\n characters (27) are defined. The code consists of 33 non-printable and \n 95 printable characters and includes both letters,\n punctuation marks, numbers and control characters. \n\n");
printf (" ASCII code: benefits and areas of application : \n   ASCII is still widely used today, even though UTF-8 \n has become more important when presenting a text. \n However, Unicode has only been displacing the old character encoding method used \n during the early days of the internet since 2008. The advantage of using UTF-8 \n is that the code is almost backwardly compatible: \n ASCII is a subset of UTF-8, so the first 128 characters are identical. \n Since ASCII can be considered the lowest common denominator of most new encoding forms, \n the old encoding method is still used in emails and URLs. \n In addition, ASCII has long been used for artistic purposes as well as \n technical ones: ASCII art uses exclusively printable \n ASCII table characters to produce creative works. \n The spectrum ranges from lettering, to simple stick figures, to real paintings. \n ASCII artists use the different brightness levels of individual \n characters to create light and shade in their artworks.  \n\n");
