"WebbIf Integer data type int is of 4 bytes, then the range is calculated as follows: 4 bytes = 4 X 8 = 32 bits Each bit can store 2 values (0 and 1) Hence, integer data type can hold 2^32 values In signed version, the most significant bit is reserved for sign. So, 0 denotes positive number and 1 denotes negative number. Hence " - Range of integer in cpp
