Question

I have a structure Defined in the Header file for a class i am working in, and i am trying to use the Struct in one of the methods of the class. It looks basically like this:

struct example
{
     double a;
     int b;
     ...
};

in the header above my class definition, and then in the cpp file, i have:

void exampleclass::test(){

    struct example *teststruct;
    teststruct->a = 0; //This line causes a access violation

}

why do i get an error here? Im sure im doing something clompletly wrong here, and i must say im a huge structure rookie.

Answer 1

What about allocating the memory for your structure ?

something like :

example* teststruct = new example;
teststruct->a = 0;
