Variablesare names given to computer memory locations in order to store data in a program. This data can be known or unknown based on the assignment of value to the variables. Variablescan also be considered as ‘containers’ which are used to hold more than one value. Their sole purpose is to label and store data in the memory and then this Variable...
The process of creating a variable is also known as Declaration of Variable. Every programming languagehas its own way of declaring a variable. Declaration of a variable does 2 things : 1. It tells the compiler what the variable name is. 2. It specifies what type of data the variable will hold. In general, the declaration consists of 3 parts – the ...
We use the= sign to assign values to the declared variables. The variable name and type will come on the left side, while the value to be stored will be on the right side.
