#pragma once
#include<iostream>
#include<SFML\graphics.hpp>

class ship{
   private:
           sf::Texture st;
           sf::Sprite ss;
           int frame ;
   public:
           int xvel;
       int yvel;
           int life;
           ship(float x,float y);
           void move(sf::RenderWindow &name);
           };
ship::ship(float x ,float y)
{
        life=100;
        if(!st.loadFromFile("bul1.png")){std::cout<<"error";}
        ss.setTexture(st);
        ss.setPosition(x,y);
        frame = 2;
}
void ship::move(sf::RenderWindow &name)
{
        if(sf::Keyboard::isKeyPressed(sf::Keyboard::Up)){ yvel-=0.8;}    
        if(sf::Keyboard::isKeyPressed(sf::Keyboard::Down)){ yvel+=0.8;}
        if(sf::Keyboard::isKeyPressed(sf::Keyboard::Left))
         { xvel-=0.8;
          --frame;}
        if(sf::Keyboard::isKeyPressed(sf::Keyboard::Right))
         { xvel+=0.8;
          ++frame;}
        else if(!sf::Keyboard::isKeyPressed(sf::Keyboard::Left)&& !sf::Keyboard::isKeyPressed(sf::Keyboard::Right)){frame=2;}

        if(frame>4){frame=4;}
         else if(frame<0){frame=0;}

        if(frame==0){ss.setTextureRect(sf::IntRect(0,0,22,43));}
        else if(frame==1){std::cout<<"f2";
                ss.setTextureRect(sf::IntRect(42,0,33,43));}
        else if(frame==2){ss.setTextureRect(sf::IntRect(86,0,43,43));}
        else if(frame==3){ss.setTextureRect(sf::IntRect(140,0,33,43));}
        else if(frame==4){ss.setTextureRect(sf::IntRect(194,0,22,43));}
        ss.move(xvel,yvel);
        name.draw(ss);
        std::cout<<"draw";
}

#include "stdafx.h"
#include <SFML\graphics.hpp>
#include "ship.h"

{sf::RenderWindow app(sf::VideoMode(800,600),"test");
sf::Texture bt;
bt.loadFromFile("spw.jpg");
sf::Sprite background(bt);
ship player(400,300);
while(app.isOpen())
{       app.clear();
    app.draw(background);
        sf::Event x;
        while(app.pollEvent(x))
                {if(x.type==sf::Event::Closed){app.close();}}

okay .. iknow that this question has been asked many times and i have even checked out the topics but i just cant seem to get my head around this problem
#include <SFML\graphics.hpp>
#include "stdafx.h"

int main()
{
        sf::Texture img;
        if(!img.loadFromFile("bg.png"))
        {std::cout<<"load error";}
        sf::Sprite bg(img,sf::Rect<int>(10,12,30,23));
        sf::RenderWindow app(sf::VideoMode(640,480),"test");
        while(app.isOpen())
        { sf::Event x;
        while(app.pollEvent(x))
        {if(x.type==sf::Event::Closed){app.close();}}
        app.clear(sf::Color(0,0,0,0));
        app.draw(bg);
        app.display();
        }
return 0;
}

my texture could not have gone out of scope as there is only a main function and even the image is getting loaded as it does not show any error
plzz help
