Can we compare character with character

Question

using if / switch statements
ex. if( char == name) where char and name are characters

Answer 1

My english is not so good you mean "character" as "letter" or "character" as type?
In javascript for example (check or first letter "one" string is the same as first letter "two" string:)
var one = "cat";
var two = "cow";
if(one.charAt(0) == two.charAt(0)){
alert("thesame");
}
else{
alert("different");
}
//result thesame

Answer 2

yes
