Can't access my vector variables in different conditions - c++

Question

I'm trying to do creating objects in a one condition and listing this objects in another condition, but it doesn't work.
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<Account>& 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:
int main(){
int whileCondition=-1;
string girisSecim;
vector<Account> createAccObj;
while(whileCondition==-1){
cout<<"--------------------------------------------------------"<<endl;
cout<<"??????????????????????????????????????????????????????"<<endl;
cout<<"1-create acc 2-transferring"<<endl;
cout<<"3-enter acc 4-exit"<<endl;
cout<<"--------------------------------------------------------"<<endl;
cin>>girisSecim;
if(girisSecim=="1"){
fillVector(createAccObj); //BURDA OBJE OLUSTURULUYOR
}
else if(girisSecim=="2"){
printVector(createAccObj);
}
else if(girisSecim=="3"){
}
else if(girisSecim=="4"){
return 0;
}
else{
cout<<"Hatali tuslama."<<endl;
}
whileCondition=0;
cout<<"Programa devam etmek icin -1'i, cikmak icin herhangi bir seyi tuslayiniz."<<endl;
cin>>whileCondition;
}
Edit: I edited the main part.
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.

follow the lifetime of createAccObj.
it seems like you do not send the same vector to both functions.
I will have a guess, your code looks like this:
while (input}(
vector<Account> createAccObj;
if(input=="1"){
fillVector(createAccObj);
}else if(input=="2"){
printVector(createAccObj);
}
here, on each iteration, new vector is created, so when you try to print, you print empty vector.
If this is the case, simply, remove the vector deceleration outside the loop.
Edit:
looking into the code again, seems like you forgot cout in newcreateAccObj[i].getId(); and newcreateAccObj[i].getName();
