Answer 1

Answer: size(): This function is used to return the number of elements inside the vector.

Step-by-step explanation: Took a quiz on this Hope it helps :D

Answer 2

To determine the number of elements in a vector, you can use the size() function in C++. This function returns the size of the vector, which is the number of elements it contains.

Step-by-step explanation:

Counting Elements in a Vector
To determine the number of elements in a vector, you can use the

size()

function in C++. This function returns the size of the vector, which is the number of elements it contains. Here's an example:

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

int main() {
vector<int> myVector = {1, 2, 3, 4, 5};
int sizeOfVector = myVector.size();
cout << "The size of the vector is: " << sizeOfVector << endl;
return 0;
}

In this example, the

size()

function is called on the

myVector

vector and the result is stored in the

sizeOfVector

variable. The output of this program will be "The size of the vector is: 5".
