I cant access my vector variables in different conditions

im trying to do creating objects in a one condition and listing this objects in another condition, but it doesn't work.Its like that.

void fillVector(vector<Account>& newcreateAccObj){ 

    string name;
    string password;

    cout<<"Enter your surname:"<<endl;
    cin>>name;
    cout<<"Enter your password:"<<endl;
    cin>>password;

    Account newAcc(name,password);
    newcreateAccObj.push_back(newAcc);
    cout<<endl;

}

-----this works fine.-----

void printVector(vector& newcreateAccObj){

unsigned int size=newcreateAccObj.size();

for(unsigned int i=0;i<size;i++){

    cout<<"Account"<<i+1<<endl;
    cout<<"-----------"<<endl;
    newcreateAccObj[i].getId();
    newcreateAccObj[i].getName();
    cout<<endl;

}

}

--this works fine too when i execute these 2 functions in same condition.--

--but when i do this--

if(input=="1"){

            fillVector(createAccObj);

        }

else if(input=="2"){

            printVector(createAccObj);

        }

I choose option 1 first.I create my object and returning the select menu, after that i choose option 2 and it gives me a blank output.

THX FOR HELP.
