Question

Which of the following statements is true? A. Interpreted programs run faster than compiled programs. B. Compilers translate high-level language programs into machine language programs. C. Interpreter programs typically use machine language as input. D. None of the above.

Answer 1

Answer:

B.

Explanation:

Computer programs are written in high level languages. Every language has its own set of syntax and semantics.

Computer only understands instructions in machine language which is written using strings of 0 and 1.

Thus, for execution of a high level language program, it is mandatory to convert high level instructions into machine instructions.

This translation into machine language is done in two ways – compilation or interpretation.

Some languages are compiled while others are interpreted.

Both compilers and interpreters are programs and process the high level language program as needed.

Compiler

Any program written in high level language is compiled.

The program is first analyzed before compilation. This process takes time. The analysis phase is called pre processing.

The program compilation stops only when the program is completely analyzed. Hence, it is difficult to locate the error in the program. This makes debugging easy.

Debugging is defined as removal of errors in the programs.

A compiler is responsible for converting high level language code into machine level code.

The complete program undergoes compilation at the same time.

A compiled program executes faster than an interpreted program.

A compiled program produce machine code which is a collection of 0 and 1, hence, it takes less time to execute.

Examples of compiled languages are C and C++.

Interpreter

Some high level languages are interpreted.

The high level language code is translated into an intermediate level code. This intermediate code is then executed.

The analysis of the program takes less time and takes place before interpretation begins. The analysis phase is called pre processing.

An interpreted program is translated one line at a time.

The program interpretation stops when an error is encountered. This makes debugging easy.

Debugging is defined as removal of errors in the programs.

Examples of interpreted languages include Python and Ruby.

Answer 2

Answer:

The correct answer is B. Compilers translate high-level language programs into machine language programs.

Explanation:

Compilers translate high-level language programs into machine language programs, It is a program that translates the human-readable code to an object/machine code in other to translate the source code into an executable program.
