    Vectors work when they want to.

    Makes 0% sense.

    I understood and still understand how to make vectors, but now it doesn't work, what the hell?

    push_back is acting like a dick, it gives me an error when I try to call it, even though it's been called like this before, pfft.. It's weird.

    Code:
    #include <string>
    #include <vector>
    
    std::vector<int> vec;
    Yes we know this works, and push_back works.

    Code:
    
    
    vec.push_back(12);

    But this doesn't work, and I even used vectors before, and even used this, now it doesn't work. Lol C++ is REEEEAALLY GREAT

    Post the errors you're getting and tell us how it's "not working".

    std::vector<int> vec();

    Code:
    1>(6) : error C2143: syntax error : missing ';' before '.'
    1>(6) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
    1>(6) : error C2371: 'test' : redefinition; different basic types
    1>        (4) : see declaration of 'test'

    The code that's failing to compile would help, too.

    It was in the OP..

    Fine..
    Code:
    #include <string>
    #include <vector>
    
    std:: vector<int> vec;
    
    vec.push_back(12);

    The compiler is complaining about something named "test". I don't see that in the code.

    That's because I'm changing code around. :P Basically, it's the same thing every time, regardless of what the variable name is.

    There is a space between your declarations std:: and the vector object

    Just a number '12' can be seen as a 'const int' , in which case your specialisation is not correct. Try to define an int equal to 12, and then push back that int. Although I don't suspect this from being the error...
    Code:
    std::vector<int> vec();
    this shouldn't make any difference...

    Post the complete piece of code you're trying to compile, not just snippets. And if you're copy-pasting code, you have to be careful that you don't get any hidden HTML chars in it.

    Neither std::vector<int> vec(); nor const work.

    That's a declaration of a function named vec that takes no arguments and returns a std::vector<int>.
