Quiz on C Program Structure and Execution

What is the purpose of the `#include ` directive in a C program?

• To define the `main` function

• To include standard input-output functions

• To declare variables

• To perform arithmetic operations

Where does the execution of a C program start?

• At the `#include` directives

• At the `main` function

• At the `return` statement

• At any function defined in the program

Which of the following is a valid way to define the `main` function?

• `int main()`

• `void main()`

• `main()`

• All of the above

What is the role of the `return 0;` statement in the `main` function?

What happens during the preprocessing phase of a C program?

• The code is compiled into machine language

• Preprocessor directives like `#include` are processed

• The `main` function is executed

• The program is linked with libraries

What is the purpose of the compilation phase in a C program?

• To convert the source code into executable machine code

• To link the program with libraries

• To preprocess the source code

• To execute the program

What does the linker do during the execution of a C program?

• Translates the source code into object code

• Links the object code with libraries to create an executable

• Executes the program

• Handles preprocessor directives

In which phase are syntax errors detected in a C program?

• Preprocessing

• Compilation

• Linking

• Execution

What is generated by the compiler as the output of the compilation phase?

• Object file

• Source file

• Executable file
