Base64 encoding of String in Qt 5
base64, c++, qt, qt5
Solution
The identifier it can't find is `base64_encode`. This is because it doesn't come until later in the file. The usual way of preventing this error is to put a function prototype at the beginning of the file or in a separate include header:
QString base64_encode(QString string);
You could also just rearrange the code so that anything depending on the definition comes last, i.e. move `main` to the end.
Problem
I am trying to base64 encode a `QString` in Qt5 . However, I am getting an error saying `identifier not found` on line `QString b64string = base64_encode(src);` ``` #include <QCoreApplication> #include <QByteArray> #include <QBitArray> #include <QString> #include <QDebug> int main(int argc, char *argv[]) { QCoreApplication a(argc, argv); QString src = "Hello"; QString b64string = base64_encode(src); qDebug() << "Encoded string is" << b64string; return a.exec(); } QString base64_encode(QString string){ QByteArray ba; ba.append(string); return ba.toBase64(); } ``` Why is the error occurring? can someone point out my mistake?
