Need help coding with assigning the size of a Vector (C++)

[EvanET]

I am prompted to: Assign the size of vector sensorReadings to currentSize.

Assigning is the double equal sign (==) but i get an extremely long error

i am given this much code:

#include <iostream>
#include <vector>
using namespace std;

int main() {
vector<int> sensorReadings(4);
int currentSize = 0;

sensorReadings.resize(10);
//begin student answer
sensorReadings.resize(10) == currentSize; //my answer
//end student answer
cout << "Number of elements: " << currentSize << endl;

return 0;
}

Hi EvanET! :)

Assigning means using an assignment (=) instead of a comparison for equality (==).
So we should have something like [M]currentSize = ?[/M].
Does [M]vector<int>[/M] have a method to retrieve its size, so that we can assign it to [M]currentSize[/M]?

are you meaning like -> .resize?

I'm thinking more like [M].size()[/M]. (Thinking)

Hmmm.. ok.

sensorReadings.size() = currentSize;

so like that?

Well, we can really assign to the size() method...
It should be more like:

currentSize = sensorReadings.size();

currentSize = sensorReadings.size();

WOW(Headbang)

i just had it backwards this whole time (Giggle)

i previously tried it as:

sensorReadings.size() = currentSize;

i guess i just need to read it right to left, so to speak.
