Variable
• Variable is a name given to the memory location.
• Declared by writing Type Variable_Name ;
• Initialized and declared by Type Variable_Name = Value ;
• EX : int a ; / float a, b, c; / etc.
Rules for defining a variable in C
- Can contain alphabet,digits and underscore(_).
- A variable name can start with alphabet and underscore only.
- It can’t start with number/digit.
- No whitespace and reserved keywords are allowed.
- Valid Names : int meet, int abc_xyz , int _a, int a4.
- Invalid Names : int 4a , int long , int &sra.
