Complete Modern C++ - If and switch with Initialization

The video tutorial explains the importance of using variables within their intended scope to avoid unnecessary pollution of the outer scope. It covers the use of index variables in for loops, memory allocation with malloc, and the enhanced capabilities of if and switch statements in C-17, allowing for initialization within these statements. Examples include checking for null pointers and writing strings to files, demonstrating how to manage variable scope effectively.

How can unnecessary variables be avoided in the outer scope when using loops and conditionals?

Describe how the visibility of a stream object differs when created inside a conditional block versus outside.
