if the'\r' appears does it mean it start from the beginning of the line again?
i mean : "(*xxxxxx  '\r'*) "---> " *)"  isn't it?
if the above one is true, what will b the output for this one
(  '\r'(1+2)
i mean i've found space after '(' so it's Invalid now right?  \but when '\r'
appears it start again from the begginning of the line so ' (1+2) '
replace '(' so the now it's valid???????
** '\r'==carriege return
