What are some examples of inlining in different programming languages?

Inlining is a technique where function calls are replaced with the function's body to improve performance. For example, in C++, you can use the 'inline' keyword to suggest the compiler to inline a function.

Can you give me a specific example in C++?

Sure! Here's a simple example:

inline int add(int a, int b) {
    return a + b;
}

When you call add(2, 3), the compiler may replace it with 2 + 3 directly in the code.

What about Java? Is inlining used there?

In Java, inlining is not explicitly defined like in C++, but the Just-In-Time (JIT) compiler optimizes method calls at runtime, effectively inlining frequently called methods to improve performance.

Are there any downsides to inlining?

Yes, inlining can increase the size of the binary if used excessively, leading to code bloat. It may also hinder debugging and optimization if not managed properly.
