General / getline skips the first line of txt file, if i use myFile >> str before it. Why?

« on: July 24, 2017, 02:33:55 pm »

Hello everyone. Does anyone knows, why getline() skips the first line of txt file, if i use myFile >> str before it? I mean if i output some amount string of file before using getline, then it will skip that amount of lines and would output only those one, that are left.
Does someone know why?

#include <SFML/Graphics.hpp>
#include <string>
#include <iostream>
#include <fstream>

using namespace std;

int main() {
    std::string output;
    std::ifstream openfile("map1.txt");

    if (openfile.is_open()) {
        std::string tileLocation;
        openfile >> tileLocation;

        while (!openfile.eof()) {
            std::string str;
            std::getline(openfile, str);
            cout << "string: " << str << endl;
        }
    }

    return 0;
}

General / Event::TextEntered strange behavior..

« on: July 22, 2017, 12:12:26 pm »

Hello everyone, i've just begun to learn SFML (couple days), my knowledge in c++ is average, i've read "C++ Primer", Lippman and already have some c++ code experience.
I have this simple code and my problem is, that it actually does't outputs characters to my console. It outputs everything i've typed AFTER i close the window. But, if i uncomment the << endl; statement, it outputs characters typed in real time. It seems i can't output my typed characters in real time, without having a new line after each character, which is super strange.
If anyone knows, please help)
P.S Sorry for my bad english sometimes, probably, i'm not a native speaker(

#include <SFML/Graphics.hpp>
#include <iostream>
#include <string>

int main() {
    sf::RenderWindow window(sf::VideoMode(500, 500), "SFML works!");
    std::string display = "";
    window.setKeyRepeatEnabled(false);
    while (window.isOpen()) {
        sf::Event event;
        while (window.pollEvent(event)) {
            if (event.type == sf::Event::Closed) {
                window.close();
            }

            else if (event.type == sf::Event::TextEntered) {
                std::cout << (char)(event.text.unicode) /* Try to uncomment THIS << std::endl */;
            }
        }

        window.display();

    }
    return 0;
