Solved String to ASCII value and vice-versa.

This is for C++.

I have a String variable containing alphanumerical characters.
How can I get the ASCII value of each character?
For example, if my String variable is "a1b2", how can I get the ASCII values of each character (97,49,98,50)?

And, if I have an Int32 variable containing a numerical value, how can I create a String out of that ASCII value.
For example, if my Int32 variable has a value of 102, how can I create a String that contains "f" ?

I have been going through the documentation but these simple conversions, that are so basic in other languages, are not simple to understand in the C++ documentation.

Maybe not the best solution but this seems to work:

	maxon::String str = "a1b2"_s;
	Int32 ascii = 102;

	// convert string to ASCII
	for (Int32 i = 0; i < str.GetLength(); ++i)
		char c = (char)str[i];
		Int32 a = (Int32)str[i];
		ApplicationOutput("'@' position @ has char @ (ascii = @)", str, i, c, a);

	// ASCII to string
		maxon::String ascii2str;

		ApplicationOutput("ascii value @ results into string '@'", ascii, ascii2str);

	// alternative
		maxon::String ascii2str;
		iferr(ascii2str.Insert(0, char(ascii)))

		ApplicationOutput("(alternative) ascii value @ results into string '@'", ascii, ascii2str);

Output to console:

'a1b2' position 0 has char 97 (ascii = 97)
'a1b2' position 1 has char 49 (ascii = 49)
'a1b2' position 2 has char 98 (ascii = 98)
'a1b2' position 3 has char 50 (ascii = 50)
ascii value 102 results into string 'f'
(alternative) ascii value 102 results into string 'f'

Thank you very much.
It seems to work :-)


just FYI: you find information on how to access individual characters from a string in the manual: String Manual

Also, one of our examples includes checking the ASCII value of a given character: streamconversion_impl.cpp
