Which of the following is an example of a compiled language?

C++ is an example of a compiled language because it is typically transformed from source code into machine code through a compiler before execution. This means that the C++ code is processed and translated into an executable format that the computer's hardware can run directly. The compilation process helps optimize the code for performance and often results in faster execution time compared to interpreted languages, where the code is executed line by line at runtime.

In a compiled language like C++, the developer writes the program in human-readable code and must then use a compiler to convert that code into a lower-level language, which the machine can understand. This stage is crucial as it allows for various optimizations that enhance the program's efficiency.

In contrast, languages such as Python, JavaScript, and PHP are primarily interpreted rather than compiled. This means they are executed line-by-line or at runtime, which can lead to slower performance compared to compiled languages like C++.
