Regarding programming languages, C and C++ are among the most influential programming languages used in software development. Both have played a significant role in software engineering evolution, so knowing the differences can help you choose which one to learn. This question is becoming more relevant as 2024 approaches.
Origins and Evolution
C Language: C was created by Dennis Ritchie in the early 1970s at Bell Labs. Many even refer to it as a precursor of modern programming languages because it has introduced powerful yet simple methods of developing softwares. In fact, C is procedural language hence focuses on step-wise instructions for carrying out tasks. It is particularly known for being efficient, having hardware control features and its part in the making UNIX operating systems possible.
C++ Language: It is a C based language that was developed by Bjarne Stroustrup in the early 1980s to add object-oriented programming (OOP) features to C. Nevertheless, it still maintains the efficiency and control associated with C, but it introduces ideas like classes, inheritance and polymorphism. Consequently, over time, this programming language has been shaped into one that can support different kinds of programming paradigms such as procedural, object oriented, and generic programming.
Key Differences Between C and C++
- Programming Paradigm:
C is a procedural programming language operating with functions focused on top down approach in its design.
On the other hand, C++ can be categorized as a multi-paradigm language that supports procedural programming, object oriented programming and generic programming. This allows for more flexibility in designing software particularly where complex and large scale applications are involved.
- Object-Oriented Programming:
C does not have any built-in features for object-oriented programming (OOP). However, one can apply OOP principles using structures and function pointers which is quite cumbersome and not very intuitive.
Contrarily, C++ was created with OOP concepts in mind. It provides support for classes, objects, inheritance, polymorphism, encapsulation etc., making it easier to model real-world problems and develop reusable code too.
- Memory Management:
Memory allocation is done manually in C by use of malloc() and free(). This enables programmers to have control over memory at low level but also leads to memory leaks among other issues.
C++ on the other hand uses RAII(Resource Acquisition Is Initialization) technique together with smart pointers which makes memory management safer compared to manual method. The new operator is used for dynamic memory allocation while delete operator frees up this space. Additionally, C++ comes with automatic garbage collection features which reduce chances of making mistakes related to managing your own memory
Standard Template Library (STL):
There are no STLs in
C++ has the Standard Template Library (STL) that contains a set of ready-made algorithms (e.g. search, sort) and data structures (e.g. vectors, maps, linked lists). It is important to note that the use of this library quickens software development and improves code quality.

Function Overloading and Templates:
The programming language C does not allow function overloading, which is the ability to have multiple functions with the same name but different argument types.
On the other hand, C++ allows developers to design functions with similar names but different parameters such as function overloading. Moreover, templates are introduced in C++ allowing users to create generic classes or functions capable of working with any type of data.
Error Handling:
C employs traditional error handling techniques like errno and return codes that are often cumbersome and prone to errors.
Exception handling was introduced in C++, which offers a more structured and really safer way of dealing with errors. By using exception handling in C++, it becomes possible for creators to separate error handling codes from main logic hence resulting into cleaner codes which can be easily maintained.
Performance Considerations
Both languages are known for their performance prowess albeit in different areas:
System-level programming, embedded systems and low-level hardware access situations frequently choose C due to its simplicity and lack of extra baggage that makes it very efficient at helping programmers achieve high levels.

Which one will you learn by 2024?
Consider studying C if:
Systems programming, developing software for resource-limited environments or embedded systems interests you. You have a desire to know how the software interacts with the hardware in a low-level way. Your intention is to work on legacy code bases or contribute to open-source projects written in C.
Learn C++ if:
Creating applications across a wide range, games, real time systems or high-performance programs is your interest. You need to learn object-oriented programming and design patterns which are essential for today’s software development. If you want to pursue a career in finance industry, game development or any other business that requires solidly built and scalable software solutions.

Conclusion
Both C and C++ have specific advantages that make them strong languages. The decision between the two is based on future aspirations, project types, and industries of interest. By 2024, mastering C can give a good foundation in programming especially for tasks at the system level. In contrast, C++ has more diverse applications making it important in modern software development.
