Question

Explain the concept of variable and data type by suitable example? 1

Answer 1

Variables are name given to memory locations which can be used to store data of a particular type. Every variable has a particular data type which is nothing but informs the compiler the type of data the variable is going to receive

Explanation:

Example: int A;

• Here A is the name of the variable

• int is the data type which tells the compiler that A can only take integers and throw an exception when the programmer gives some random input maybe characters like a,b,c,etc.
