POProblem for template class<class_name> that has bitset as argument
text
Body
copied!<p>I want to write a class in C++ in which one of the parameter is a <code>bitset<size></code>. I want to give the facility to vary this "size" for any object of that class but should be constant for that object.</p> <p>If I make a variable <code>const int size;</code> and initialize it in the constructor, then it does not compile because to writiting <code>bitset<size></code> would require <code>size</code> to be static which would make it same for all objects of the class.</p> <p>Is there any other method than making a class template and passing the size as <code>classname<size></code>?</p> <p>thanks but.. but this makes this Foo class objects whenever used as composition (object as data member)... would it be necessary to again make that class template. I made a class and Passed a (#define BIT_SIZE 16 to Foo bits;) it is giving compile errors undefined reference to Foo<16>::Foo(). where Foo() is the constructor. I thought it should work because that is also compile time. and i just wanted to make only size BIT_SIZE bits. should i make my "next level" class template ?? it can be that these errors were because of other mistakes. but i checked that again and again.</p> <hr> <p>yes sir i have implemented that and but included the header files and not cpp files .......... when i changed these to cpp files ... multiple declaration error came. i am working on linux ubuntu .. when i took these files to dev_cpp in windows that worked . may be because compiler did that automatically what i need to do. so what is that i need to do.</p>
