2010年8月12日 · Interesting that these answers utilize printf like it is a given.printf converts the integer to a Hexadecimal string value.

Note that 0 - 127 (0 to 0111 1111) in hex shows as expected, because the sign bit is 0, so when going from 8-bit to 32-bit its extended with 0's (which show as blank in the hex). Once you get to 128 (1000 000) signed char, it becomes a negative number (-128), and it is sign-extended with 1's / …

2021年4月26日 · Note that using %#X will use upper-case letters for the hex digits and 0X as the prefix; using %#x will use lower-case letters for the hex digits and 0x as the prefix. If you prefer 0x as the prefix and upper-case letters, you have to code the 0x separately: 0x%X .

I am currently attempting to read in Hex values from a text file. There can be multiple lines of Hex's and each line can be as long as needed: f53d6d0568c7c7ce 1307a7a1c84058 b41af04b24f3eb83ce Currently, I put together a simple loop to read in the Hex values into an unsigned char line[500] with fscanf as such:

2011年11月21日 · Convert a long hex string in to int array with sscanf. I have seen some topics on this before, but most solutions are in Python (curse you for being so easy!).
