## Unnecessary Curly Braces in C : Why the Fuss and What\'s the Impact?

Unnecessary Curly Braces: A Peculiar Coding Practice

In a recent code review, many developers have observed an unusual practice: enclosing code within unnecessary curly braces. The question is, what impact does this have and why is it being done?

The practice stems from C, where nesting loops and conditional statements introduced new scopes for variables. This allowed developers to declare variables within specific blocks without worrying about naming clashes. However, in C , variables can be declared anywhere within a scope.

Additionally, C introduces destructors, providing automatic cleanup of resources. This eliminates the need for explicitly releasing resources, which was a common reason for using curly braces in C.

In the specific example provided, the enclosed code appears to be a series of boolean operations and checks. It declares a new variable, isInit, whose scope is limited to the curly braces. While this may provide a sense of organization, it is not necessary in C .

Instead of relying on curly braces to control scope, it is more conventional to use methods to organize and separate code. This allows for logical grouping of operations and improves code readability. Moreover, it eliminates potential confusion about variable scope and reduces the likelihood of naming conflicts.
