Can we access RAM?
How? Whats the range of access?
Similarly What are other hardware we can access?
Answer / shrirang phadke
Yes, we can access RAM using "far" pointer as follows...
int main()
{
char far *s;
s = 0x413;
/*-- desired code goes here --*/
return 0;
}
Now pointer(*s) is pointing to the base of Memory...
But, i guess far pointers works only in 16-bit enviornment.
Similarly, using far pointer we can access keyboard(0x417)
as well as Moniter(0xB8000000).

Write a program which has the following seven functions. The functions should be: • main() this calls the other 6 functions • fget_long() a function which returns a long data type from a file • fget_short() a function which returns a short integer variable from a file • fget_float() a function which returns a floating point variable from a file • fprt_long() a function which prints its single, long argument into a file • fprt_short() a function which prints its single, short argument into a file • fprt_float() a function which prints its single, floating point argument into a file. You should use fscanf() to get the values of the variables from the input (the file) and fprintf() to print the values to the other file. Pay attention to using the correct format for each of the data types.

A float occupies 4 bytes in memory. How many bits are used to store exponent part? since we can have up to 38 number for exponent so 2 ki power 6 6, 6 bits will be used. If 6 bits are used why do not we have up to 64 numbers in exponent?
