"WebAn Integer is a wrapper class for int and provides more flexibility in comparison to the int. 3. Purpose: It is used for only a single purpose, i.e., storing an integer value into memory. Its main purpose is to convert an int into an object or an object into an int. 4. Memory use: It takes 4 bytes to store an integer value in it. " - Compare size_t and int
