If we want to get the last char from string, how can we get it?

Question

string x = "I know C#";
char x = ???????

Answer 1

char lastCharacter = x[x.length - 1]

in your example, you can't give both the string and char variables the same name

Answer 2

char getLastChar(string s) {
return s[s.Length-1];
}

Answer 3

char need root like charoot

Answer 4

Tomek example is right, but we need to think about exception... If string is empty this example will be generate error message.

Answer 5

string x = "I know C#";
char x = str[8];

This example can only be used if you know the exact amount of chars in the string, so as uos mentioned you can delve a little further into other examples to handle exceptions or more robust code.

Answer 6

Look up a character at index method similar to the one in Java. Then pass the parameter variableName.length() as the parameter in the character at method. This will always give the index of the last character in the string.
