WebOkay so here's the description for 'int' and 'long int': They both take up 4 bytes. The signed and unsigned values of 'int' AND 'long int' is: int = -2147483648 to 2147483647; and 0 to 4294967295. long int = -2147483648 to 2147483647; and 0 to 4294967295. Both 'int' and 'long int' have the same properties for signed and unsigned. Webint: 4 bytes: long: 8 bytes: float: 4 bytes: double: 8 bytes: long double: 16 bytes .
