Difference between Function and Procedure

In this article, we will discuss two important terms that are function and procedure, along with their comparison. The procedure is an important and frequently used programming construct for a compiler. It is used to generate good code for procedure calls and returns.

The function contains the set of programming statements enclosed by {}. It provides code reusability and modularity to the program.

Hope the article will be helpful to you and gives you knowledge about function, procedure, and their comparison. So, without any delay, let's start the topic.

Function

In a programming language, function is said to be a set of instructions that take some input and execute some tasks. A function can either be predefined or user-defined. In the C program, a function can be called multiple times to provide reusability and modularity. It may or may not return a value.

Procedure

It is an important programming construct for a compiler. The procedure is used for generating good code for procedure calls and returns. It does not deal with an expression. It is defined as the set of commands that are executed in order.

In DBMS, a procedure (often called a stored procedure) is a collection of pre-compiled SQL statements stored inside the database. It is a subroutine or a subprogram in the regular computing language. A procedure always contains a name, parameter lists, and SQL statements. In structured query language (or SQL), it does not return a value. In Java, both function and procedure are the same and called sub-routines.

Function v/s Procedure

Now, let's see the comparison between both function and procedure. We are tabulating the difference between both terms based on some characteristics.

So, that's all about the article. Here, we have seen the comparison between function and procedure along with their separate discussion.
