copy Assignment operator ?? Constructor ??

[onkar]

class Base{

// some stuff

};

int main(void){
Base a;
a=Base(10);
return 0;
}


what are the constructors called ?? Is copy assignment operator also
called in this situation ?? If yes how is it defined ??

You can find your answer here:

Hope that helps.

class Base{

// some stuff

int main(void){
Base a;
a=Base(10);
return 0;

}

what are the constructors called ??

Default constructor in the first line of main. Constructor from
int in the second line of main.

Is copy assignment operator also
called in this situation ??

Obviously, since you have an assignment in the second line of
main.

If yes how is it defined ??

However you've defined it. By default, it calls the copy
assignment operator for each of the base classes, then the copy
assignment operator for each member.

If your C++ book doesn't explain this in detail, it's time to
change books.
