We transitioned from punch cards to programming languages because programming languages provide a much more user-friendly and efficient way to interact with computers. Punch cards required users to manually enter instructions and data, which made programming a difficult and error-prone procedure. However, these low-level hardware features were abstracted by programming languages, allowing programmers to communicate with computers using human-readable language. This update highlights that the purpose of programming languages is to simplify and improve the effectiveness of computer teaching, hence improving accessibility and reducing the cognitive load on developers.
Because different problems require different approaches. Specific objectives, such readability, system performance, or suitability for tasks (like web development, machine learning, and hardware programming), are considered while creating programming languages. This variety lets developers pick the best tool for each problem. For example, Python is often suggested because it’s easy to use and has many tools for data science. But when more control over hardware and memory is needed, C is a better choice. Also, programming languages change as new technology develops, which gives even more options.
One drawback of Python is its performance—since it's an interpreted language, it's slower compared to compiled languages. Applications that need fast performance, like handling big data or real-time calculations, can struggle with delays. For example, running a complex algorithm in Python can take much longer than using a language like C. Another disadvantage of Python is that its high memory and resource requirements make it unsuitable for embedded systems. Python doesn’t provide the strong hardware control or low memory usage that embedded systems often require. To improve Python, I'd like to see better optimization for performance, perhaps through more effective just-in-time (JIT) compilation or integration of lower-level control for embedded systems. To make Python more versatile for IoT and robotics development, some examples include integrating lightweight libraries or tools that enable the language to be utilized in embedded hardware or microcontroller-based projects.
First, I will think about what the language is meant to do and who will use it. I want to make sure it can solve real problems. Then, I will focus on making the rules simple and easy to understand. At the same time, I will focus on the memory and complexity of the language to make it fast enough to fit today's technology. Furthermore, I would have to construct the back-end code generator and the front-end compiler for the source code. A piece of software called the front-end compiler takes the source code and outputs an odd-looking data structure. Another piece of software that takes whatever the front-end created and turns it into code that actually works is the back-end code generator.
