Quick wins with RAII
- Resource management in C++ extends beyond memory. We often need to work with files, mutexes, database connections, and other system resources. Failing to manage these resources correctly can cause problems ranging from data loss to system-wide resource exhaustion. Let's have a look at the common example of manual resource management working with files. Now, this code has several potential issues. What happens if an exception occurs while processing the file? The fclose call would never be reached, leaving the file handle open. We could add try catch blocks, but that makes the code more complex and error prone. RAII offers a much cleaner solution. This acronym stands for resource acquisition is initialization. The core idea behind RAII is elegantly simple. Linking resource management to object lifetime lets C++ automatically manage resources during object creation and destruction. Here's how it works. Every object should acquire the resources it needs upon initialization. Resource…
