   • What does 0x0F mean? And what does this code mean?

     Top Answer

     Answered Mar 23, 2015 · 21 votes

     >>> is the unsigned bitwise right-shift operator. 0x0F is a hexadecimal number which equals 15 in decimal. It represents the lower four bits and translates the the bit-pattern 0000 1111. & is a bitwise AND operation.

     (x >>> 4) & 0x0F gives you the upper nibble of a byte. So if you have 6A, you basically end up with 06:

     6A = ((0110 1010 >>> 4) & 0x0F) = (0000 0110 & 0x0F) = (0000 0110 & 0000 1111) = 0000 0110 = 06

     x & 0x0F gives you the lower nibble of the byte. So if you have 6A, you end up with 0A.

     6A = (0110 1010 & 0x0F) = (0110 1010 & 0000 1111) = 0000 1010 = 0A

     From what I can tell, it looks like it is summing up the values of the individual nibbles of all characters in a string, perhaps to create a checksum of some sort.

   • what does for(); mean? what does this ; (semicolon) mean that comes after for() in c code instead of {}?

     The body of a for loop can be any statement. That includes a compound statement:

     for(...) { do_something;}-

     Or a single statement:

     for(...) do_something;-

     One of the types of statements is a null statement, which is just ;. So this:

     for (length = 0; t[length]; length++);-

     Is a loop whose body is the null statement ;. It's the same as:

     for (length = 0; t[length]; length++) {}-

   • What does void(*)() mean in code

     Top Answer

     It is a cast to a function pointer (with no returned result and no arguments). I prefer using typedef to define signature of such functions:

     typedef void plainsig_t(void);-

     then simply code

     (*(plainsig_t*)shellcode) ();-

     For function pointers, you don't need to dereference them, so it is shorter to just code:

     ((plainsig_t*) shellcode) ();-

     which basically calls the function whose machine code is located inside shellcode memory zone.

     BTW, this is not strictly portable C. In principle, there is no guarantee that you can cast a data pointer to a function pointer. (On some weird processors -e.g. embedded microcontrollers, DSP, 1970s era computers-, code and data sit in different address spaces, or have different pointer sizes, etc....). But most common processors and ABI (x86-64/Linux, ARM/Android, ....) have the same address space for code and for data and accept casting function pointers to data pointers and vice versa.

   • What does this code mean? OpenCV

     Top Answer

     Answered May 23, 2017 · 1 votes

     Short answers:

     • x is the element on row j, column i of the matrix df_dx
     • df_dx->imageData returns a pointer to the first element of the array (top-left)

     Accessing matrix elements in such a way is actually quite common for 2d matrices stored in memory as flat one-dimensional arrays (see e.g. GSL matrix accesses for a similar example with another library; see also this post for a similar question).

     Storing a matrix as an array of arrays (i.e. using [][] for access) is definitely manageable, and many people chose to use this representation, but there are reasons why one would prefer a flat layout in memory.

     OUT_PINS is a macro defined with some 2D array values. check the following example for better understanding.

     eg: int *OP[] = {OUT_PINS } is similar to

     int *OP[] = {{X2_PIN, PIOC, ID_PIOC, PIO_OUTPUT_0, PIO_DEFAULT}, \ {Y2_PIN, PIOC, ID_PIOC, PIO_OUTPUT_0, PIO_DEFAULT}, \ {Z2_PIN, PIOC, ID_PIOC, PIO_OUTPUT_0, PIO_DEFAULT}}

   URL escape codes for characters that must be escaped lists the characters that must be escaped in URLs. If you must escape a character in a string literal, you must use the dollar sign ($) instead of percent (%); for example, use query=title%20EQ%20"$3CMy title$3E" instead of query=title%20EQ%20'%3CMy title%3E'.
