How does using 'const' in C++ affect performance?

How does using 'const' in C++ affect performance?

Using 'const' in C++ can improve performance by enabling compiler optimizations and ensuring that variables are not modified.

Can you give an example of how 'const' can be used in a function?

Sure! You can use 'const' in function parameters to prevent modification, like this: void myFunction(const int value) { ... }.

Does using 'const' have any impact on memory usage?

Generally, using 'const' does not directly affect memory usage, but it can lead to better optimization by the compiler.

Are there any downsides to using 'const'?

One downside is that it can make code less flexible, as you cannot modify 'const' variables. However, the benefits often outweigh this.
