Answer / Santosh Kumar Rena
In C, an integer variable stores whole numbers (positive or negative), and the size depends on the system you're using. Some common types include char (one byte), short int (two bytes), int (four bytes), and long int (eight bytes). A floating-point variable is used to store real numbers with a decimal point, such as float (four bytes) and double (eight bytes). Character variables are used to store characters and are enclosed in single quotes (').
