How do I write inline functions?

Inline Functions in C++

Inline functions are a feature in C++ that allows you to suggest to the compiler to insert the function's code directly into the code at the call site, instead of performing a traditional function call. This can lead to performance improvements, especially for small, frequently-called functions.

Benefits of Inline Functions

• Reduced function call overhead
• Optimized performance for small functions
• Improved readability and maintainability

Syntax of Inline Functions

To define an inline function, simply use the inline keyword before the function's return type:

When you call this function in your program, the compiler will try to replace the call with the actual code of the function.
