How do i increment letters in c++?

Question

I\'m creating a Caesar Cipher in c++ and i can\'t figure out how to increment a letter.

I need to increment the letter by 1 each time and return the next letter in t

Answer 1

Does letter++ work? All in all char is a numeric type, so it will increment the ascii code. But I believe it must be defined as char letter not an array. But beware of adding one to 'Z'. You will get '[' =P

#include 

int main () {
    char a = 'a';
    a++;
    std::cout << a;
}

This seems to work well ;)
