Description

An enumerated data type is useful to keep track of features

Demo Code

enum ShapeType {/*from   w  w w .  j  a v  a 2s  .  co m*/
   circle,
   square,
   rectangle
};  // Must end with a semicolon like a struct
int main() {
   ShapeType shape = circle;
   // Activities here....
   // Now do something based on what the shape is:
   switch(shape) {
      case circle:  /* circle stuff */ break;
      case square:  /* square stuff */ break;
      case rectangle:  /* rectangle stuff */ break;
   }
}

Add initialized value for enum value. 

enum ShapeType {
   circle = 10, square = 20, rectangle = 50
};

The compiler can and will use the next integral value if you miss it. 

enum snap { crackle = 25, pop };
