Variable Declaration

Variable Declaration is a concept where we'll create memory space(Usually in RAM) for a value and letting system know following information regarding that memory space
1. Name of the variable
2. Type of value it holds
3. The initial value if any it takes.

Syntax
datatype name = value ;

Sample Variable Declaration
int age = 25;
In the above variable Declaration, system will allot 32-bit memory space in RAM and that memory space will be named as age and initial value stored inside is 25

NOTE:
We can blindly follow syntax for declaring variables but When it comes to char datatype we need to give values inside single quotation marks ('value'), when it comes to string we need to give values inside double quotation marks("value"). For all the other datatypes we can directly give the values.
char symbol = '$';
string sentance = "We are Coders Capsule!";
