What is an entry point in programming?

An entry point in programming refers to the location in the code where execution begins. This is critical in any program because it signifies the first line of code that is executed when the program runs. In many programming languages, this is typically the main function or method. Understanding the entry point is vital for grasping how a program flows and how various functions or procedures are called thereafter.

The concept of the entry point is foundational in understanding program structure and control flow, as it sets the stage for everything that follows in the execution of the program.
