Explanation:
In computer programming, function is a block of reusable codes which are grouped to perform a specific task. The usage of function enable the program written in a more structured and modular style that help people to better understand the program. A well written function can reduce code redundancy as well.
One example of function (written in Python) that perform a specific task such as calculate area of rectangle is as follows:
def calculateArea(width, height):
area = width * height
return area
We can simply use the function by calling its name and passing two input values for width and height as follows:
calculateArea(5, 6)
This will give us 30.
