Hi, I have been searching a while for a way to convert acsii code to and from a string, any help is appreciated.
By 'ASCII code', do you mean, say, you have a string of numbers
65 101 116 and you want to convert it to a string
"Eat"?
Well, converting an
int to a
char should work.
chars store the letters by (usually) their ASCII representations
anyway, so the following should work:
1 2 3
|
int x = 97;
char c = static_cast<char>(x);
std::cout << c << '\n'; // a
|
I'll leave it to you to work out how to convert a string of numbers into a string of characters :)

48 65 6c 6c 6f is hex for Hello, I wanna translate this to char.
You can use
std::hex to signify you are reading hexadecimal values:
1 2 3
|
int x;
std::cin >> std::hex >> x;
std::cout << static_cast<char>(x) << '\n';
|
Alternatively, if you already have a string with it in, you can use
std::stringstream and
std::hex like above or use
std::stoi:
1 2 3
|
std::string s = "48";
int x = std::stoi(s, nullptr, 16);
std::cout << static_cast<char>(x) << '\n';

What if its a very long string, like for example 49 20 4c 49 4b 45 20 59 4f 55 52 20 53 4f 43 4b 20 4d 38
