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