The values range of integers are shown in the following table [3]: WebAn integer type variable occupies 4 bytes of memory in 32-bit and 64-bit systems. Hence sizeof(int) is 4. Why is the sizeof(int) 2 or 4 bytes? The size of a data type varies for different machines depending on the processor used (16-bit, 32-bit or 64-bit) Thus, the sizeof(int) is 2 bytes for a 16-bit machine and 4 bytes for a 32-bit and 64-bit ...
