In programming, it often denotes a literal value, such as a number, a string, or a boolean, or a variable that represents such a value. It is the building block from which more complex expressions are constructed. An alapkifejezés cannot be further decomposed into simpler components without losing its meaning or identity. For instance, in the expression `2 + 3`, both `2` and `3` are alapkifejezések. Similarly, in `x * y`, `x` and `y` would be considered alapkifejezések if they are variables.
The concept of an alapkifejezés is crucial for understanding how expressions are evaluated and parsed. It forms
