You should ues the QProcess class to start your program.

QString program = "./main";
QStringList arguments;
arguments << "-testing" << "45" << "563" << ...;

QProcess *myProcess = new QProcess(parent);
myProcess->start(program, arguments);

Then you can use the waitForFinished to wait for it to finish. exitCode will give you the return code.

The readAllStandardOutput (or *Error) methods allow you to read what the process has output to the console.

Thank you. But I have one question. readAllStandardOutput returns QByteArray. If program will write - (7\n67\n78\n), what format will be qbytearray?

It will have exactly that format. You can create a QString from a QByteArray, or create a QBuffer from it.
