Use QTimer or QElapsedTimer if you need more precision.

main.cpp

#include 
#include 
#include 
#include 
#include 

int main(int argc, char **argv)
{
    QCoreApplication application(argc, argv);
    QTimer timer;
    QTextStream textStream(stdout);
    QString word = "apple";
    int i = 0;
    QObject::connect(&timer, &QTimer::timeout, [&textStream, word, &i] () {
        if (i < word.size()) {
            textStream << word.at(i) << flush;
            ++i;
        }
    });
    timer.start(1000);
    return application.exec();
}

main.pro

TEMPLATE = app
TARGET = main
QT = core
CONFIG += c++11
SOURCES += main.cpp

Build and Run

qmake && make && ./main

Output

apple
