What are assertions in C++?

What are assertions in C++?

Assertions in C++ are used to verify assumptions made by the program. They help catch bugs by checking conditions at runtime.

How do I use assertions in my code?

You can use the assert macro from the <cassert> header. For example: assert(x > 0); will terminate the program if x is not greater than 0.

Can I disable assertions in release builds?

Yes, you can disable assertions by defining the NDEBUG macro before including <cassert>. This will prevent assertions from being checked.

Are there any alternatives to assertions?

Yes, you can use exception handling or logging for error checking, but assertions are simpler for debugging purposes.
