The integer is the primary data type used to store numerical data when a decimal value is not needed. A variable of the integer type can contain numbers ranging from -32,768 to 32,768. An integer is defined using the int keyword.
We can declare an integer to be unsigned by using the unsigned keyword. An unsigned integer can range from 0 to 65,535 whereas the normal integer has a range of -32,768 to 32,768. The following code shows how we would define both a regular integer and an unsigned integer:
int mySignedInt = 25; unsigned int myUnsignedInt = 15;
In the preceding code, we declared a variable named mySignedInt of the integer type with an initial value of 25. We also declared a second variable named myUnsignedInt of the unsigned ...
