1) A function called `is_equal` takes two float arguments and returns a bool value.
Write the function prototype for the `is_equal` function.

2) The `display` function displays a value in a formatted manner.
It takes one argument, an integer, that represents the value to be displayed. It returns nothing.
Write a calling statement for the `display` function that will display the value 247.

3) Assume the following array has been created and initialized:
`double values[15] = { 1.8, 3.4, 2.7, 7.1, 9.4, 13.3, 14.0, 15.3, 12.4, 19.6, 42.7, 99.9 }`;

a) What value is stored in `values[14]`?
b) What value is stored in `values[9]`?
c) What is the result of `values[10] - values[8]`?
d) What is the result of `values[9] + 2.4`?

Answer :

1) The function prototype for the "is equal" function, which takes two float arguments and returns a bool value, can be written as:

bool isEqual(float arg1, float arg2);

2) To call the "display" function and display the value 247 in a formatted manner, the calling statement can be:

display(247);

3a) The value stored in values[14] is 99.9.

3b) The value stored in values[9] is 19.6.

3c) To calculate the result of values[10] - values[8], we subtract the value at index 8 from the value at index 10.

values[10] - values[8] = 42.7 - 12.4 = 30.3

3d) Since the term "values b" is not defined in the question, it is difficult to determine the result of "values b + 2.4."

What is an array?

An array is a data structure that stores a fixed-size sequence of elements of the same type. It provides a way to store multiple values under a single name. Each element in the array is identified by its index, which represents its position in the sequence. Arrays can hold elements of any data type, such as integers, floating-point numbers, characters, or custom objects.

Arrays have a contiguous block of memory where the elements are stored. This allows for efficient access to individual elements using their index. The index of the first element is typically 0, and the index of the last element is the total number of elements minus one.
