What is poiner value in c?
In c a pointer is a variable that points to or references a memory location in which data is stored. Each memory cell in the computer has an address that can be used to access that location so a pointer variable points to a memory location we can access and change the contents of this memory location via the pointer. Pointer declaration A pointer is a variable that contains the memory location of another variable. The syntax is as shown below. You start by specifying the type of data stored in the location identified by the pointer. The asterisk tells the compiler that you are creating a pointer variable. Finally you give the name of the variable. type * variable name Example: int *ptr; float *string;

You can use a memory move function like memcpy to transfer 20 consecutive bytes from one memory location to another memory location. Make sure to specify the source, destination, and the number of bytes to transfer.
What is the name of the instructions to move data from one location in memory to another location in memory?
hey if its in the context of strings we can use string manipulation functions like strcpy(). in microprocessors we use rep movsb to move data from one memory location to other.

How many address lines are needed to address each machine location in a 2048 X 4 memory chip?
It depends on how wide the data buses are on each chip, and how they're connected. If they're one byte wide, you could need over 256 million addresses, one for each byte. if they're wider, and connected to show an even wider combined data bus, it could be much less; around 32 million.
