The line code will create array is G = array('f',[2.5, 3, 7.4])
<h3>What is meant by array ?</h3>
As opposed to defining distinct variables for each value, arrays are used to hold numerous values in a single variable. Set the data type (such as int) and the array name, followed by square brackets [, to construct an array.
An array is a collection of elements with the same type that are kept in nearby memory locations and may each be separately referred to using an index to a special identifier. There is no need to declare five distinct variables when declaring an array of five int values (each with its own identifier).
In the C programming language, arrays are a derived data type that may contain primitive data types like int, char, double, float, etc.

The function use to get the number of element in a dictionary is len.
<h3>What is a dictionary?</h3>
Dictionaries are used to store data values in key-value pairs. Dictionary are ordered.
Dictionary in python are express as follows:
my_dict = {"name": "Michael", "age": 28, "school": "Oxford"}
Therefore, the length of the element of the dictionary can be gotten using the len() function.
Hence,
print(len(my_dict)) will give you the length of the element.

The following cose will be used to copy assignment operator for CarCounter
<u>Explanation:</u>
Complete Program:
#include <iostream>
using namespace std;
class CarCounter
{
public:
CarCounter();
CarCounter& operator=(const CarCounter& objToCopy);
void SetCarCount(const int setVal)
{
carCount = setVal;
}
int GetCarCount() const
{
return carCount;
}
private:
int carCount;
};
CarCounter::CarCounter()
{
carCount = 0;
return;
}
// FIXME write copy assignment operator
/* Your solution goes here */
CarCounter& CarCounter::operator=(const CarCounter& objToCopy)
{
if(this != &objToCopy)
carCount = objToCopy.carCount;
return *this;
}
int main()
{
CarCounter frontParkingLot;
CarCounter backParkingLot;
frontParkingLot.SetCarCount(12);
backParkingLot = frontParkingLot;
cout << "Cars counted: " << backParkingLot.GetCarCount();
cout << endl << endl;
system("pause");
return 0;
}
the answer is the seconf one
