Converting a char to ASCII?
c++, visual-studio-2010
Solution
A `char` is an integral type. When you write
char ch = 'A';
you're setting the value of `ch` to whatever number your compiler uses to represent the character `'A'`. That's usually the ASCII code for `'A'` these days, but that's not required. You're almost certainly using a system that uses ASCII.
Like any numeric type, you can initialize it with an ordinary number:
char ch = 13;
If you want do do arithmetic on a `char` value, just do it: `ch = ch + 1;` etc.
However, in order to display the value you have to get around the assumption in the iostreams library that you want to display `char` values as characters rather than numbers. There are a couple of ways to do that.
std::cout << +ch << '\n';
std::cout << int(ch) << '\n'
Problem
I have tried lots of solutions to convert a char to Ascii. And all of them have got a problem. One solution was: ``` char A; int ValeurASCII = static_cast<int>(A); ``` But VS mentions that static_cast is an invalid type conversion!!! PS: my A is always one of the special chars (and not numbers)
