#include <QHostAddress>
using namespace std;
tcpclient::tcpclient(QObject* parent): QObject(parent)
  connect(&client, SIGNAL(connected()),this, SLOT(startTransfer()));
void tcpclient::start(QString address, quint16 port)
  QHostAddress addr(address);
  client.connectToHost(addr, port);
void tcpclient::startTransfer()
  client.write("hello world", 12);
   char buffer[1024]/* = "Hello world"*/;
   connect(&client, SIGNAL(readyRead()),this, SLOT(receivedata()));
void tcpclient::receivedata()
    char buffer[1024] = {0};, client.bytesAvailable());
     cout << buffer << endl;
    client.write("inifinity sending", 18);

DON'T SHOUT. Using all capitals is considered shouting on the internet, and rude (using all lower case is considered childish). Use proper capitalisation if you want to be taken seriously.
