Question

We covered a number of math functions such as floor(x), tan(x), degrees(x) etc. What benefits can you see with using functions? More importantly, what two other functions besides the math functions could a programmer use?

Answer 1

Advantages of functions.

They enable us hide implementation details of a program. For instance, we have used floor(x), tan(x), degrees(x) without ever having the knowledge of how they were implemented.

Use of functions improves the readability of a program which makes it easy to read and understand.

Using functions also help avoid duplication of code in programs

Other functions a programmer can use are standard library functions, user defined functions and built in functions
