Int, short for "integer," is a fundamental variable type built into the compiler and used to define numeric variables holding whole numbers. Other data types include float and double. C, C++, C# and many other programming languages recognize int as a data type.
Consequently, what is the difference between int and integer?
The following are the differences: - Integer is a wrapper class, where as int is a primitive data type. - Integer can be used as an argument to a method which requires an object, where as int can be used as an argument to a method which requires an integer value, that can be used for arithmetic expression.
What is an int variable?
Integer Number Variables. The first type of variable we need to know about is of class type int - short for integer. An int variable can store a value in the range -32768 to +32767. You can think of it as a largish positive or negative whole number: no fractional part is allowed.
