Program Elements: Program is a set of instructions.Every Program consists,
- Identity
- Variables
- Functions
- Identity:
- Identity of a program is unique.
- Programs, Classes, Variables and Methods having identities
- Identities are used to access these members.
- Variable:
- Variable is an identity given to memory location.
- Variable is also Called “Named Memory Location”
- Variables are used to store information of program(class/object)
| Syntax | Examples |
| datatype identity = value; | int age = 23; double salary = 35000.00; char gender = ‘M’; char* name = “Amar”; |
- Function:
- Function is a block of instructions with an identity
- Function performs operations on data(variables)
- Function takes input data, perform operations on data and returns results.
| Syntax | Example |
| returntype identity(arguments) { body; } | int add(int a, int b) { int c = a+b; return c; } |
