How many characters i can store in a character array while i am having a ram of 1 GB.
That depends on your OS and compiler.
If you're using crusty old turbo C, then 64K is your limit no matter how much RAM you have.
But a more modern combination which allows you to use virtual memory might allow you to store more than your physical memory.
On windows (32-bit), the maximum limit would be 2GB with default settings, 3GB if you apply the /3GB switch in your boot.ini - of course, that would make it REALLY slow. If you want reasonably fast access to the content of a char array, limit it to about 80% of RAM-amount (unless you have other large applications).Quote:

One megabyte by default in Windows. Subtract from that all the space normally needed, and you end up with a max length of perhaps 800-900k, if the program does nothing else.
Under no circumstances will you be able to use more than 3 gigs of continuous memory in 32-bit Windows, and that requires special tricks. By default, you have 2 gigs of freely available address space. Furthermore, memory fragmentation means that you will probably not be able to allocate all the memory there is into a continuous block.
Lots! How many do you need?Quote:
