Why might a machine dependent language be more appropriate for writing certain types of programs?

Answer 1

Machine dependent languages often have the advantage of being able to be optimized, since the compiler knows what hardware it's running on. Any program which needs to run efficiently will often benefit from being written in a machine dependent language.

Answer 2

They can and they do!

These days we have all manner of computer languages available to us, but computers don't understand any of these languages any more than we understand machine code. Machine code is the computer's native language after all; it is nothing more than a very long series of 1s and 0s to us. Difficult to read and, more importantly, difficult to maintain.

However, when we write code in a high-level language, such as C++, we are actually producing the necessary machine code that the computer can understand. With modern compilers, the resultant code can be every bit as efficient as if we'd entered the machine code by hand.

Nowadays, the closest we actually get to writing machine code by hand is assembly language. Assembly is a low-level language that can be used alone or in conjunction with high-level languages, to produce highly efficient machine code wherever it is required. Some programmers still write entirely in assembly, but all too often coders are far more concerned with features than efficiency. Hence much of today's software can be highly-inefficient compared to similar programs written by old-school coders who use the right tools for the job.

As an aside, we also use assembly to reverse-engineer machine code, more accurately referred to as disassembly.

Answer 3

here's two example, decide which you prefer:
machine code: 7f c5 00 8a 79 12 45
C: a= b+c

The C language is a "high level" language which is easily understandable by the users than the machine codes that are "low level" language.

Answer 4

Machine-independent languages are portable, so you can write your program once and use it on many different architectures with little or no changes.

Answer 5

12 c5 5d 66 73 f8 76 00

It is an example machine code, it's up to you decide if it is easier to use than C language.

Answer 6

1. Because it is easier for users to understand.

2. The c language is a high level which is easily understandable by the users than the machine codes that are low level.
