bit is 63 bytes. In 32-bit machines, long is 4 bytes, the highest byte is the symbol bit, and the data bit is 31 bytes. The Signed Conversion Function strtol truncates "3000000000" to 2147483647 (the maximum number of signed four-byte positive values, that is, the binary number is 0111 1111 1111 1111 1111 1111 1111 1111 ). Use strtoul to correctly handle the error (valid for the number of 4-byte unsigned characters ). Similarly, for 8-byte unsigned numbers, strtoull is required. Otherwise, even
