this wiki page gave a general idea of how to convert a single char to ascii http://en.wikibooks.org/wiki/Ruby_Programming/ASCII
But say if I have a string and I wanted to get each character’s ascii from it, what do i need to do?
'string'.each_byte do |c| $char = c.chr $ascii = ?char puts $ascii end It doesn’t work because it’s not happy with the line $ascii = ?char
syntax error, unexpected '?' $ascii = ?char ^
The
cvariable already contains the char code!yields
