Answer:

False.

Explanation:

When we declare a variable as reference type we have to initialize that variable otherwise the compiler will give error that the reference variable is not initialized.You also cannot initialize the variable Foo& with NULL value because it is a reference variable and we have to initialize it.

On the other there is no need to initialize the variable Foo * since it is a pointer it can also store NULL value.

So the answer is only Foo* can store NULL value not Foo &.

NISA [10]

Answer:

Galen expanded on the Hippocrates' theory of humor by assigning personalities, moods, behaviors, and emotions to the four humors. He believed blood stood for sanguine personality, black bile for a melancholic personality, yellow bile for a choleric personality and phlegm for a phlegmatic personality.

Explanation:

Hippocrates put forward the theory of the four humors. According to the theory, the human body is made up of four substances: black bile, yellow bile, blood, and phlegm. A healthy human body is the product of a balance of among the four humors, while diseases results if there is an imbalance among the four humors.

Galen, a keen admirer of Hippocrates' ideas, further elaborated on this theory and believed that they affected personalities, moods, behaviors, and emotions.

The personalities assigned the four humors are as follows:

People with predominantly black bile are Melancholic (corresponding to the season of autumn dry and cold): They are very sensitive, and enjoy artistic pursuits.

People with predominantly yellow bile are Choleric (corresponding to the season of summer, dry and hot): They possess a passionate temperament, They have a lot of ambition, energy, drive, enormous vitality but are domineering and get angry quickly.

People with predominantly blood are Sanguine (corresponding to the season of spring, wet and hot): These people are confident, joyful, optimistic, expressive, confident, rational and sociable.

People with predominantly phlegm are Phlegmatic (corresponding to the season of winter, wet and cold): They are deep thinkers, fair, calm, very consistent, relaxed, and observant, willing to compromise, and hard workers.

earnstyle [38]

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.
