WebApr 10, 2024 · Besides the minimal bit counts, the C++ Standard guarantees that 1 == sizeof (char) ≤ sizeof (short) ≤ sizeof (int) ≤ sizeof (long) ≤ sizeof (long long).. Note: this allows the extreme case in which bytes are sized 64 bits, all types (including char) are 64 bits wide, and sizeof returns 1 for every type.

WebFeb 1, 2024 · In a computer, characters are stored as numbers, so char holds integer values that represent characters. The actual translation is described by the ASCII standard. Here’s a handy table for looking up that. The actual size, like all other data types in C, depends on the hardware you’re working on. By minimum, it is at least 8 bits, so you ...
