I was wondering if someone could help me on figuring out how to create multiple structs and also counting the number of structs created. My Code follows three blocks, header file, Television file and then the main file.
Television.h

string Model; //Smart, regular
string Connection; //HDMI, VGA

int Screen_size;
int Resolution; //larger one, so 1920 and etc.
int Channel; //any number
int Volume; //0 - 100
public:

};

Basically, my code only allows me to create one object and modify it. However, I would like to add the ability to create multiple objects and have a counter for it. I tried adding a counter, but it seems that doesn't work very well... I don't need someone to solve it, but if someone could point me to the right direction, that would be great.
