Question

The following code shows an example of ____:

double square(double number)
{
return (number * number);
}

a. coupling
b. functional cohesion
c. tight coupling
d. loose coupling

Answer 1

The correct answer is Option B. The code example represents functional cohesion, where a function performs a single specific task, which in this case, is calculating the square of a given number.

Step-by-step explanation:

The provided code example demonstrates an instance of functional cohesion. Functional cohesion exists when the elements of a module, such as functions in a software program, are grouped together because they all contribute to a single, well-defined task. In this case, the function named square takes a double-precision floating-point number (double) as an argument and returns the result of multiplying this number by itself, effectively computing its square.

The example code provided is an illustration of functional cohesion. Functional cohesion refers to a type of cohesion in software design where all the functions or methods within a module are related and contribute to a single well-defined task or responsibility. In this case, the code demonstrates a single function, square, which takes a double number as input and returns the square of that number.
