appending string or int to vector variable

[flavourofbru]

Hi,

Is it possible to add an int or a string or a char to a vector variable??
For example if I declare a vector variable as follows:
vector<string> abc;

Can I append an integer value or some string value to the vector variable such that every time I call a function that has this declaration, it creates a new vector variable abc appened with the int or string value?

Is there any other method by which I can do above operation

Please help.

Thanks,
Rishi

i dont think tht u can append the vector variable like tht
but if i m able to guess ur functionality then u can be better using array of vectors or vector of vectors. Then u can access the sub(contained) vectors like a[0], a[1] and so on. If u can clarify more on ur problem (or requirement) then may be we can help further.

If I understand you correctly, you should be able to write a function template to do that:

[code=cpp]
template< typename T>
vector<T>* MyFunction(T& arg)
{
vector<T>* temp = new vector<T>;
temp->push_back(arg) ;
return temp;
}
int main()
{
int i = 30;
vector<int>* val = MyFunction(i);
string str("Hello");
vector<string>* val1 = MyFunction(str) ;
}
[/code]

If I misunderstand, my apologies.

Hi,
My exact problem is clearly defined below:
Please look at the following code:

dependencies(in t i)
{
string str;
vector<string> fd;
cout<<"enter the attributes of fd"<<i<<endl;
cin>>str;
fd.push_back(st r);
}

int _tmain(int argc, _TCHAR* argv[])
{
int num;
cout<<"Enter the number of functionaldepen dencies"<<endl;
cin>>num;
for(int i=0; i<num; i++)
{
dependencies(i) ;
}
return 0;
}


In the above code I am calling the function "dependenci es" depending on the given input for number of functional dependencies. In the "dependenci es" function, whatever i am inputting is pushed into the vector. But everytime I call the function, the input that I give gets into the same vector.

But what i want to do is, everytime I call the function dependencies, it should create a new vector and push that iteration inputs into new vector instead of pushing into the same old vector.

Is it possible to do that way??

Please help!!

Thanks!!

Take a close look at your dependencies function. Each time you call it, it will create a new and "local" vector of strings. Since it is local, each time you leave dependencies, the vector and its values are deleted. I doubt this is what you want.

Now take a look at MyFunction in post #3. It creates a new vector on the "heap" each time it is called. It returns a pointer to that vector so that the calling program can use the vector. I think this is what you want.

Add your loop to MyFunction or add the vector creation to dependencies and return the new vector.

flavourofbru,

I noticed you had posted a new thread containing this very same question. Please limit your question to one thread in the future - there's no need to have 2 discussions happening at once on the same subject!

Thanks a lot.
