WebWe know that the data type “int” has the size of 4 bytes where it can hold values from -2 31 to 2 31 – 1, but in this, we have declared “x” as unsigned int so it can hold values from 0 to 2 32 – 1. The unsigned int can contain storage size either 2 or 4 bytes where values ranging from [0 to 65,535] or [0 to 4,294,967,295].
