Const Variables in C++

This Snippet is coded by a user inOnline cpp Compiler. You can see and run this code too.

زبان: C++

This code demonstrates the use of the const keyword in C++. A constant variable named myNum is initialized with the value 15.

Constants in C++ are read-only, and any attempt to modify them results in a compile-time error.

When the line myNum = 10; is executed, the compiler throws:

error: assignment of read-only variable 'myNum'

This prevents accidental modifications, making your code safer and more predictable.
