How many bytes is a short in c++

WebAug 6, 2024 · 1. 1. To generalize, an object with n bits (where n is an integer) can hold 2 n (2 to the power of n, also commonly written 2^n) unique values. Therefore, with an 8-bit byte, a byte-sized object can hold 2 8 (256) different values. An object that uses 2 bytes can hold 2^16 (65536) different values! Thus, the size of the object puts a limit on ... WebThe size of the character pointer is 8 bytes. Note:This code is executed on a 64-bit processor. 2. Size of Double Pointer in C As we already know, the size of pointer in C is machine-dependent, so the size of the double-pointer should be the same as that of the character-pointer. Let us confirm that with the following code. #include
