Question

How a program, using C compiler, is executed on a host machine?

a. Preprocessing, Compilation, Assembly, Linking
b. Compilation, Linking, Execution
c. Compilation, Execution, Preprocessing
d. Preprocessing, Execution, Compilation

Answer 1

A program using a C compiler is executed on a host machine through the steps of preprocessing, compilation, assembly, and linking.

Step-by-step explanation:

The correct sequence of steps for executing a program using a C compiler on a host machine is:

1. Preprocessing: In this step, any preprocessor directives like include statements, macros, and conditional compilation are handled.
2. Compilation: The source code is compiled into object code by the C compiler.
3. Linking: The object code is linked with other necessary libraries to create an executable file.
4. Execution: Finally, the executable is loaded into memory and executed by the computer's operating system.

Therefore, the correct option is a. Preprocessing, Compilation, Assembly, Linking.
