C++ Changing Default Value of Enums
To change the default value of an enum in C++, you can follow these steps:
- Define the enum type: Start by defining the enum type using the
enum
keyword followed by the name of the enum type. For example:
cpp
enum Color { RED, GREEN, BLUE };
- Assign explicit values: By default, the first enumerator in an enum has a value of 0, and the subsequent enumerators have values incremented by 1. To change the default values, you can assign explicit values to the enumerators. For example:
cpp
enum Color { RED = 10, GREEN = 20, BLUE = 30 };
In this case, the enumerator RED
will have a value of 10, GREEN
will have a value of 20, and BLUE
will have a value of 30.
- Use the enum: You can now use the enum type in your code by declaring variables of the enum type. For example:
cpp
Color myColor = RED;
Here, myColor
is a variable of type Color
, and it is assigned the value RED
.
By following these steps, you can change the default values of enums in C++.
