Enum is group of related constants. it will improve the readability of the program. it will not improve the performance of the program. Enum TestingStatus { YetToStart = 0; InProgress=2; Completed=3 };

Multiple benifits: 1. You can provide meaningful names for constant values and use the names to refer to the constant values. This increases the readability of the code and results in better understanding. 2. Better parameterization of the code. If you need to change the value, you don't need to make...

Multiple benifits: 1. You can provide meaningful names for constant values and use the names to refer to the constant values. This increases the readability of the code and results in better understanding. 2. Better parameterization of the code. If you need to change the value, you don't need to make changes in multiple places. Just change the enum definition and your program is valid with new values. 3. enums help the programs by helping them make fewer mistakes. [for ex., usage of a wrong constant], missing to change the value in some places]These mistakes will not be syntactical and hence compiler will not catch. Just that program misbehaves. read less

Using the enum keyword to define a constant can have several benefits. First, constants declared with enum are automatically generated by the compiler, thereby relieving the programmer of manually assigning unique values to each constant. Also, constants declared with enum tend to be more readable to the programmer, because there is usually an enumerated type identifier associated with the constant's definition. Additionally, enumerated constants can usually be inspected during a debugging session. This can be an enormous benefit, especially when the alternative is having to manually look up the constant's value in a header file. Unfortunately, using the enum method of declaring constants takes up slightly more memory space than using the#define method of declaring constants, because a memory location must be set up to store the constant. Here is an example of an enumerated constant used for tracking errors in your program: enum Error_Code { OUT_OF_MEMORY, INSUFFICIENT_DISK_SPACE, LOGIC_ERROR, FILE_NOT_FOUND }; read less

What is the actual size of INT in the C language, 2 or 4 bytes?
The actual size to int is determined by the compiler as the program runs. But theoretically the size is 2 bytes. You can increase the size by adding keyword long infront of it to make the size 4 bytes. Eg int a; // 2 bytes Long int b; // 4 bytes
