Question

Describe with examples the uses of enumeration data types

Answer 1

Enumerated Data Types: The Enumerated data type allows the programmer to invent his own data type and decide what value the variables of this data type may carry. Enum or enumerator is an integer or number with defined meaningful names. Enum is often used inside C programs to replace a hard coded numbers with some meaningful symbols

ex.
/* A function prints state of a task with numbers */ void print_task_state (int state) { switch (state) { csase 0: printf ("Task has been added.\n"); break; case 1: printf("Task is ready.\n"); break; case 2: printf("Task is running.\n"); break; case 3: printf("Task is waiting.\n"); break; case 4: printf("Task has been terminated.\n"); break; default: printf("Task in undefined state.\n"); } }
