WebThe types of these constants, other than CHAR_BIT and MB_LEN_MAX, are required to match the results of the integral promotions as applied to objects of the types they describe: CHAR_MAX may have type int or unsigned int, but never char. Similarly USHRT_MAX may not be of an unsigned type: its type may be int . WebYou seem to be misunderstanding how bits and shift work in C++. To begin: The lowest (least significant) bit is number 0.On a 64-bit number the highest (most significant) bit is number 63.. Shifting to the right moves high bits to the lower positions, filling up with zero bits at the top. Shifting to the left move bits to the higher positions, filling up with zero bits …

WebDec 26, 2024 · The maximum (unsigned) 64-bit integer is 18446744073709551615. This is (2^64)-1, which is essentially the square of (2^32)-1, which is "about" 4 billion. In general, you can estimate that every 10 bits represents 3 decimal digits. For 64 bits, that means a good estimate would be 16 (from the 4 leftover bits) followed by 18 zeroes (6*3).
