Detecting C/C++ Heap Issues In Xcode On Macos

Debug, detect & isolate memory related issues on macOS through Xcode & other standard tools

What you'll learn

Understand different kinds of problems associated with memory management

Effectively detect & isolate memory issues

Gain confidence in C/C++ memory management

Understand and use the facilities provided by Xcode for detecting memory issues

Use the standard memory debugging tools provided in macOS

Requirements

Fair knowledge of C & C++ is essential for this course

Not recommended for complete beginners to C++

Description

C++ is a large and complex language, but it gives programmers complete freedom when it comes to management of dynamic memory. This allows the programmers to allocate memory and manipulate it at runtime. That is why C++ is still a favorite language for high performance applications in various domains such as gaming, telecom, finance, aerospace, etc.However, it requires programmers to take great care while using dynamic memory, such as releasing acquired memory, taking care not to overstep memory boundary, etc. Otherwise, it could lead to problems such as dangling pointers, memory corruption, memory leaks, etc. This course will help you overcome all these problem by leveraging the tools provided on macOS platform. It has a rich set of functions provided by the C/C++ runtime heap library. These functions can help detect memory leaks, overflows, etc. You'll learn how to use these functions effectively and make your programs bug-free.In this course, you'll start with the basics of heap memory management and understand C & C++ allocation functions/operators in depth. You'll also learn how to effectively use them to avoid memory problems. Afterwards, you'll learn about the Xcode Malloc Debugging library functions and understand how to use them in your code. You'll also use the guarded memory allocator to effectively detect heap corruptions. You'll also gain knowledge of Xcode instruments, leaks command & more that can help you detect leaks.By the end of this course, you'll have a deep understanding of dynamic memory management. You'll be able to use standard tools effectively to detect & isolate memory problems. Note: This course is ONLY for macOS platform
