#includeIn this example, a QByteArray object is created with the value "Hello World!". The mid function is then used to extract a subsequence of 5 bytes starting from the position 6 in the original ByteVector. The resultant subsequence is stored in another QByteArray object and displayed using qDebug(). This code example and function are part of the Qt library.#include int main() { QByteArray bytes = "Hello World!"; QByteArray subBytes = bytes.mid(6, 5); qDebug() << subBytes; return 0; }
