Q1: What is an inline function in C++?

A. A function expanded at the point of call B. A function stored in a separate memory location C. A recursive function D. A virtual function

Q2: How do you declare a function as inline?

A. By using the inline keyword before function definition B. By using virtual keyword C. By using static keyword D. By using extern keyword

Q3: Which is a key advantage of inline functions?

A. Faster execution due to no function call overhead B. Smaller executable size C. More readable code D. Supports recursion

Q4: What happens if the inline function is too large?

A. Compiler may ignore the inline request B. Compilation error C. Program crashes D. Function is always inlined

Q5: Are inline functions allowed to be recursive?

A. Yes, but usually not inlined fully B. No, recursion disallows inline C. Yes, always fully inlined D. No, causes error

Q6: Can inline functions be defined inside a class?

A. Yes, they are implicitly inline B. No, must be outside C. Yes, but only if static D. No, causes error

Q7: Which of these is true about inline functions?

A. They increase code size if used excessively B. They reduce executable size C. They always replace macros D. They can only be used in header files

Q8: Can inline functions have multiple definitions in different files?

A. Yes, allowed if inline B. No, causes linker errors C. Yes, but only static D. No, only one definition allowed

Q9: What is the relationship between inline functions and macros?

A. Inline functions are safer and type-checked alternatives B. Macros are preferred over inline functions C. Inline functions and macros are the same D. Macros have better debugging support

Q10: Which is NOT true about inline functions?

A. They guarantee inline expansion B. They reduce function call overhead C. They can be recursive D. They can be defined in header files

Q11: How are inline functions typically defined in multi-file programs?

A. In header files B. Only in source files C. In main program file D. In a special inline directory

Q12: Can inline functions have static variables inside?

A. Yes, but static variables are shared across calls B. No, static variables disallow inline C. Yes, static variables are duplicated D. No, causes error

Q13: Does using inline functions affect debugging?

A. Debugging may be harder due to no function call B. Debugging is easier C. No effect on debugging D. Debuggers always treat inline functions as normal

Q14: What is the default linkage of an inline function?

A. Extern linkage with inline semantics B. Static linkage C. No linkage D. Internal linkage only

Q15: Which of the following should NOT be inline?

A. A large function with loops and conditions B. A simple accessor function C. A short utility function D. A function defined inside class

Q16: Can virtual functions be inline?

A. Yes, if called non-virtually B. No, never inline C. Yes, always inline D. Only if static

Q17: How does inline affect recursive function calls?

A. Only initial calls are inlined B. All recursive calls are inlined C. No inlining for recursion D. Recursion disables inline

Q18: Why prefer inline functions over macros?

A. Type safety and better debugging B. Faster execution C. Works with C and C++ D. Macros are deprecated

Q19: What happens if inline keyword is omitted?

A. Function is not inlined unless compiler decides B. Compilation error C. Function always inlined D. Function treated as macro

Q20: Which compiler directive can force inline?

A. __forceinline (MSVC specific) B. #inline C. #pragma inline D. inline
