 | A variable becomes a reference to another variable. |
| Lecture 2 - Slide 15 : 29 |
Here we show a number of examples that illustrate various aspects of references
"The absence of const in a declaration of a reference (argument) is taken as a statement of intent to modify the variable"
| A variable becomes a reference to another variable. |
| No operator operates on a reference as such. |
| A typical use of references: A number of results passed back from vector_min_max via references. |
| A function that attempts to return references to local variables. |
| Ditto - handling the problem by making the local variable static. |
| A function with reference parameters and reference return type. |
| Convenient references to long/deep fields. |
