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 ... WebFeb 1, 2024 · By minimum, it is at least 8 bits, so you will have at least 0 to 127. Alternatively, you can use signed char to get at least -128 to 127. Standard Integers: int The amount of memory that a single int takes depends on the hardware. However, you can expect an int to be at least 16 bits in size.
WebIf you will use up to 32 variables each one with a width of 1 bit, then also the status structure will use 4 bytes. However as soon as you have 33 variables, it will allocate the next slot of the memory and it will start using 8 bytes. Let us check the following example to understand the concept − Live Demo
WebSep 1, 2024 · An integer giving the maximum value a variable of type Py_ssize_t can take. It’s usually 2**31 - 1 on a 32-bit platform and 2**63 - 1 on a 64-bit platform.
