Question: 1 / 400

Does a compiler execute the program directly?

True

False

A compiler does not execute the program directly; instead, it transforms source code written in a high-level programming language into machine code or an intermediate code that can then be executed by a computer. The primary role of a compiler is to analyze the source code for syntax and semantic correctness, optimize it, and generate the target code. This process is distinct from execution, which is handled by a runtime environment or the operating system.

In contrast, execution is generally performed by a processor or virtual machine that interprets the compiled code. This is a crucial distinction because it highlights the separation between the compilation phase and the execution phase of a program's lifecycle. Thus, saying the compiler executes the program directly is incorrect, as the compiler's main job is to prepare the program for execution rather than to run it itself.
