How to assign vector size to array size c++? Ask Question Asked 6 years, 2 months ago. Active 6 years, 2 months ago. Viewed 2k times 1. How can I set the size of my array equal to the size of my vector. Here's my code: vector<Point> data_obj; int my_array[data_obj.size()] but I get compile errors saying:returns the number of elements that can be held in currently allocated storage (public member function)Question: Assign The Size Of Vector SensorReadings To CurrentSize. #include #include Using Namespace Std; Int Main() { Vector SensorReadings(4); Int CurrentSize = 0; SensorReadings.resize(10); /* Your Solution Goes Here */ CoutNotes. If value-initialization in overload (1) is undesirable, for example, if the elements are of non-class type and zeroing out is not needed, it can be avoided by providing a custom Allocator::construct. Vector capacity is never reduced when resizing to smaller size because that would invalidate all iterators, rather than only the ones that would be invalidated by the equivalent sequence ofMay anyone help guide and explain this program for me Assign the size of vector sensorReadings to currentSize. #include #include using namespace std; int main() { vector sensorReadings(4); int currentSize = 0; sensorReadings.resize(10); currentSize = 10; cout

Check if the size of the vector is 0, if not add the back element to a variable initialised as 0, and pop the back element. 2. Repeat this step until the size of the vector becomes 0. 3.

Problem:

I am wondering how can I determine the size of the array in some of the cases. I've written the under small pattern program as an example what I am looking to say.

int main(int argc, char *argv[]) std::vector<unsigned char>v; unsigned char p[1024]; sprintf((char*)&p[0], "%10d", 10); cout << "Size: " << v.size() << " Length: " << v.capability() << endl; v.reserve(30); cout << "Size: " << v.size() << " Length: " << v.capability() << endl; memcpy(&v[0], &p[0], 20); cout << "Size: " << v.size() << " Length: " << v.capacity() << endl; v.reserve(50); cout << "Size: " << v.size() << " Length: " << v.capability() << endl; v.reserve(0); cout << "Size: " << v.size() << " Length: " << v.capability() << endl; v.resize(20); cout << "Size: " << v.size() << " Length: " << v.capability() << endl; v.resize(0); cout << "Size: " << v.size() << " Length: " << v.capacity() << endl; go back 0;

So I want to know the some or the other way to tell a vector what number of elements it lately is supposed to be protecting.
