Pls help me to understand this error

#1

In this question of i compare values of char c with a and z like this:
if(“a”<=c && c<=“z”)
then it gives error but as soon as i do like this:
if(‘a’<=c && c<=‘z’) i.e use single quotes it doesnt give error

hi @kunal81198 double quotes are used for strings, single quotes are used for characters. You cannot compare a character with a string and that is why error arises in the first syntax.
