What are the differences between direct and indirect calls?
Direct calls are made to a specific function or method, while indirect calls involve a reference or pointer to the function.
Can you give me an example of each?
Sure! A direct call would be functionName();
, while an indirect call might look like functionPointer();
where functionPointer
points to functionName
.
Why would someone use an indirect call?
Indirect calls are useful for callbacks, dynamic function execution, and when working with function pointers in languages like C.
Are there performance differences between the two?
Yes, direct calls are generally faster since they resolve the function at compile time, while indirect calls may involve additional overhead.
