A disadvantage of a compiled programming language is that

it can't separate source code from an executable file.
it takes longer to run the program.
it can't run on any platform.
it executes the source code line by line.

One potential disadvantage of a compiled programming language is that it cannot separate source code from an executable file. This means that the source code is always bundled and distributed as part of the executable file. This can make it more difficult to protect intellectual property or to modify and update the program without access to the original source code.

Another disadvantage is that compilation generally takes longer compared to interpreted languages as the code needs to be translated into machine code before it can be executed. This can result in longer development and testing cycles.

In addition, compiled languages are often platform-dependent, meaning that the executable file can only run on specific operating systems or hardware architectures. This lack of portability can limit the potential user base or require the development of multiple versions of the software.

Lastly, while compiled languages execute the source code line by line, this can sometimes limit flexibility and dynamic behavior compared to interpreted languages which can execute code on-the-fly.
