WebJan 19, 2024 · byte datatype has a range from -128 to 127 and it requires very little memory (only 1 byte). It can be used in place of int where we are sure that the range will be very small. The compiler automatically promotes the byte variables to type int, if they are used in an expression and the value exceeds their range. WebIf 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. green clinical waste
