Explain integer constant with example.

An integer constant is a numerical value that represents a fixed, whole number without a fractional or decimal component.

 In computer programming, an integer constant is a value that represents a whole number without any fractional or decimal part. It can be either positive or negative.

An example of an integer constant is 42. This is a whole number and can be represented in many programming languages as simply 42, without any decimal point or fraction.

Another example of an integer constant is -7. This represents a negative whole number, and can be written with the negative sign preceding the number.

Integer constants are used extensively in computer programming, and are useful for representing counts, indices, and other numeric values that need to be represented as whole numbers.
