Question
**Understanding Interpreters in High-Level Programming Languages**

An interpreter is a type of computer program that executes instructions written in a high-level programming language. This process involves several functions essential for the program to run correctly and efficiently.

**Quiz Question:**

*What function(s) does an interpreter perform with the instructions in a high-level programming language?*

**Possible Answers:**

1. Executes
2. Translates and Execute
3. Translates
4. Compiles
5. Compiles and Translates

**Explanation of Functions:**

1. **Executes:** This option implies that the interpreter only runs the program without necessarily translating it into machine code.
   
2. **Translates and Execute:** This is the correct function of an interpreter. An interpreter translates high-level instructions into an intermediate form, usually one line or one instruction at a time, and then directly executes them.

3. **Translates:** While an interpreter does translate code, it also needs to execute the translated code, making this an incomplete answer.

4. **Compiles:** This is a function associated more with compilers than interpreters. Compilers translate an entire high-level program into machine code before execution.

5. **Compiles and Translates:** This option mixes the functions of both compilers and interpreters. It’s not entirely accurate as it doesn’t specify the execution part of an interpreter's job.

**Illustrative Diagrams/Graphs (if any):**
There are no diagrams or graphs in this specific content. 

By understanding the exact role of an interpreter, students can better grasp the differences between various types of language processors, which is crucial for software development and computer science education.
