Difference between Objective and Function
In programming, the terms objective and function are often used interchangeably. However, they have distinct meanings and it’s important to understand the differences between them to use them properly.
The main difference is that an objective is a data structure that encapsulates data and behavior whereas a function is a set of instructions that perform a specific task.
Before we move to the differences, let’s understand what are Objective and Function:
- Objective: An objective is a data structure that contains data and methods (behavior) that operate on that data. It is an instance of a class, which is a blueprint or template for creating objects.
- Function: A function, on the other hand, is a set of instructions that performs a specific task. It takes input, performs some operation on it, and returns output.

Now, let’s move to Objective vs Function:
Major differences between Objective and Function
| Objective | Function |
|---|---|
| An objective is a data structure. | A function is a set of instructions. |
| An objective encapsulates data and behavior. | A function performs a specific task. |
| An objective can be used to represent a real-world object. | A function is not used to represent a real-world object. |
| Objectives are high-level goals or purposes. | Functions are low-level blocks of code that perform specific tasks to achieve those goals. |
| Objectives are more abstract and conceptual. | Functions are more concrete and specific. |
That’s it.
Note that sometimes, the question might also be asked as “distinguish between Objective and Function”.

Final words
Objectives and functions are two distinct concepts in programming that serve different purposes. Objectives are high-level goals or purposes that guide the development process, while functions are low-level blocks of code that perform specific tasks to achieve those goals. When designing and developing a program, it’s important to define clear objectives and create functions that implement the program’s functionality in a clear and efficient way.
