Vector is not a Template?

Question

I am currently trying to follow a tutorial on making a simple 2D tile engine for top-down RPGs. For some reason though I get the intellisense error

vector is not a template

The word "vector" is underlined with red. Why does this not work? Why is it telling me that it's a template, and why does the mean the program won't work?

#ifndef _IMAGEMANAGER_H
#define _IMAGEMANAGER_H
#include <vector>
#include <SFML\Graphics.hpp>
class ImageManager
{
private:
    vector<sf::Texture> textureList;
public:
    ImageManager();
    ~ImageManager();
    void AddTexture(sf::Texture& texture);
    sf::Texture& GetTexture(int index);
};
#endif

Errors I get (no doubt some of these spawn from the error of this part above):

Solution 1

vector is from the std namespace, so you must use std:: to specify:

std::vector<sf::Texture> textureList;

Or you can use a using statement:

using std::vector;
vector<sf::Texture> textureList;

Solution 2

Since I don't see any using statements in your code sample, I am pretty sure you need to add std:: to your vector declaration, like so:

std::vector<sf::Texture> textureList;

Thank you. I used the first tip which solved it. Using the namespace would most likely have solved it too.

[OmniOwl]

The other guy listed more than one solution so I accepted his, though I up-voted yours too for effort! :3

[Shafik Yaghmour]

@Vipar No worries, you should pick the answer that helped you the most.

[Hiura]

Keep in mind that using directives are not recommended in header files.

[hmfarimani]

don't forget #include <vector>

[Ganesh S]

I also had to do #include<vector> further in addition to above solution as I got a error std has no member vector

[Admin]

Building on what Ganesh said, if you arrived here anytime after 2019, you need #include<vector> and the std::vector to use a vector.
