Formatted I/P functions: These functions allow us to supply the input in a fixed format and let us obtain the output in the specified form. Formatted output converts the internal binary representation of the data to ASCII characters which are written to the output file. Formatted input reads characters from the input file and converts them to internal form.

Unformatted I/O functions: There are several standard library functions available under this category-those that can deal with a string of characters. Unformatted Input/Output is the most basic form of input/output. Unformatted input/output transfers the internal binary representation of the data directly between memory and the file

What is the difference between cprintf and printf?
The printf function calls on fprintf to write the result of sprintf to standard output. That is:printf("%i\n", 42);is exactly equivalent to:fprintf(stdout, "%i\n", 42);

Differentiate between bounded and un bounded functions in calculus?
If you mean differentiate as in calculate the derivative then it is the same both ways, otherwise Google solving improper integrals.
What is difrrence between paste and paste special?
Paste will just paste whatever you've copied. Paste Special in Wordpad has a few options to paste in different formats which are as a Wordpad document, Rich Text Format, a picture and unformatted text. It is much more limited in options compared to Paste Special in other applications.
What is the relationship between trigonometry and differential calculus?
Just like most any other set of functions, trigonometric functions are subject to differentiation. Trig functions are cool (at least sin and cos are) because as you differentiate, they cycle through until you get back where you started.

The calculated capacity of a floppy disk is 1.47mb to hold down data while the capacity is 1.44mbthe difference is 0.03 mb explain that?
The difference in capacity vs. usable space on an 3.5 inch floppy disk is related to the FAT - file allocation table. This is an area that is reserved for machine and directory instructions. To explain what this means is that most disks are referred to their unformatted size. If you then create a 'protocol' format on the disk to support a particular operating system then this uses some of the space on the disk to do its housekeeping in. Therefore there will be a discrepency between the unformatted size and the formatted size. The same is true of hard drives which are quoted in their unformatted size, which is then reduced after formatting. The amount of space loss is congruent with the size of the disk. The larger the disk the more space is used to store the format.
