c++ - Copy constructor for a stack using linked list -



c++ - Copy constructor for a stack using linked list -

template <class t> stack<t>::stack(const stack<t>& otherstack) { list<t> the=otherstack.list; listitem<t> *temp=the.gethead(); while(temp!=null) { push(temp->value); temp=temp->next; } }

i using linked list create stack , re-create constructor not working. please help.

the re-create constructor of list<t> defined as:

template <class t> list<t>::list(const list<t>& otherlist) { head=null; listitem<t> *temp=otherlist.head; while (temp!=null) { insertattail(temp->value); temp=temp->next; } }

if list , stack have usual semantics, constructor reverses order of items in constructed object. should either traverse list in reverse order or such re-create twice restore original order. possible list can copied assignment operator ,

this.list = otherstack.list

is enough. not seeing list code can't tell.

c++

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...

javascript - mongodb won't find my schema method in nested container - i trying access method of schema stored within mixed container. here situation : have cases model can many different things, have schema each of these things stored in "casecontent" mixed property. var caseschema = mongoose.schema({ casecontent : {}, object : {type:string, default : "null"}, collision : {type : boolean, default : false} }); the casecontent property filled model of 1 of schemas, 1 exemple : var treeschema = new mongoose.schema({ applecount : {type : number, default : 3} }); treeschema.methods.dostuff = function (data) { console.log('hey, listen'); homecoming true; }; then, want utilize method of schema original container : caseschema.methods.dostuff = function (data) { if (this.casecontent.dostuff !== undefined) { this.casecontent.dostuff(); console.log('it worked'); } else { ...
