Why is the address of an array the same the array converted to a pointer?
When t is used on its own in the expression, an array-to-pointer conversion takes place, this produces a pointer to the first element of the array. When t is used as the argument of the & operator, no such conversion takes place. The & then explicitly takes the address of t (the array). &t is … Read more
One memory location in a computer stores how much data?
Most commonly, modern systems are what you call “byte-accessible”. This means: One memory location stores 1 byte (8 bits). The basic storage unit for memory is 1 byte. If you need to store 4 bytes, and place the first byte at 0001, the last byte will be at 0004. That’s one byte at each of … Read more
What exactly is the array name in c?
Other answers already explained the issue. I am trying to explain it with some diagram. Hope this will help. When you declare an array int a[3] = {5, 4, 6} the memory arrangement looks like Now answering your question: a and &a have the same values.How? As you already know that a is of array … Read more
Calling a function through its address in memory in c / c++
On modern operating systems, each process has its own address space and addresses are only valid within a process. If you want to execute code in some other process, you either have to inject a shared library or attach your program as a debugger. Once you are in the other program’s address space, this code … Read more
What does “DS:[40207A]” mean in assembly?
The instruction is loading a new EIP value from memory at ds:[40207A]. i.e. there’s a function pointer at address 40207A. (And it pushes a return address because this is a call not just a jmp.) The ds: means the instruction is referencing memory in the Data Segment – and can pretty much be ignored on … Read more
Basic use of immediates vs. square brackets in YASM/NASM x86 assembly
The square brackets essentially work like a dereference operator (e.g., like * in C). So, something like mov REG, x moves the value of x into REG, whereas mov REG, [x] moves the value of the memory location where x points to into REG. Note that if x is a label, its value is the … Read more
Executing assembler code with python
You can embed assembly directly inside your Python program: https://github.com/Maratyszcza/PeachPy https://github.com//pycca/pycca http://codeflow.org/entries/2009/jul/31/pyasm-python-x86-assembler/ https://github.com/AmihaiN/pyAsm These work by compiling the assembly and loading it into executable memory at runtime. The first three projects implement x86-64 or x86 assemblers in Python, whereas the last calls out to an external compiler.
What is the address of a function in a C++ program?
So, here the address of function and the address of first variable in function is not same. Why so? Why it would be so? A function pointer is a pointer that points to the function. It does not point to the first variable inside the function, anyway. To elaborate, a function (or subroutine) is a … Read more
Get memory address of member function?
There exists a syntax to get the address of the member function in MSVC (starting from MSVC 2005 IMHO). But it’s pretty tricky. Moreover, the obtained pointer is impossible to cast to other pointer type by conventional means. Though there exists a way to do this nevertheless. Here’s the example: // class declaration class MyClass … Read more
