If the object represents a data type, is the variable for a primitive data type like an integer also an object representing this type, or do objects not represent primitive data types?

// Let's assume I have a class called "DifferentTypes."

class DifferentTypes {
public:
    int I{};
    string str{};
    bool b{};
};// Sorry for my poor code writing

int main() {
    DifferentTypes dfft;
    dfft.I = 10;

    int x{};
    x = 10;

    return 0;
}
