The program must work in a loop, reading two integer numbers, computing the sum of them and printing out the result until instructed to quit.

The program must check the input data for the data type permitted (representation of an integer) and the data value limitations (the value of the integer must not exceed the actual size of byte-coded integers, i.e. min 00000000 and max 11111111 in Base 2 or min 0 and max 255 in Base 10).

The program must be implemented in a modular way with separate functions for inputting data, bit operations, integer operations and outputting the result of the calculation.
