call by reference
[kɔːl baɪ ˈrɛfərəns]
noun
chamada por referência
1. A programming mechanism where a function or method receives a reference (memory address) to the original variable instead of a copy of its value, allowing the function to modify the original variable
In C++, when you use call by reference with the & operator, changes made to the parameter affect the original variable.
Em C++, quando você usa chamada por referência com o operador &, as mudanças feitas no parâmetro afetam a variável original.
