Answer / vignesh1988i
the printf and sprintf functions are used to output to the
screen.....
in printf... just we can print the necessary things as
we wanted
SYNTX is:: printf("format specifiers..(%d or %c
etc)",list of agruments..(arg1,arg2... arg n);
hrewr this function directly output whatever you are giving
inside ....
but sprintf is called Stream printf... where it will store
whatever we output to the screen in an array (ie..stream)
and then output to the screen;;;
sprintf(array base address,"format specifications",variables);

Answer / jack
The printf subroutine converts, formats, and writes the
Value parameter values, under control of the Format
parameter, to the standard output stream.
The sprintf subroutine converts, formats, and stores the
Value parameter values, under control of the Format
parameter, into consecutive bytes, starting at the address
specified by the String parameter. The sprintf subroutine
places a null character (\0) at the end. You must ensure
that enough storage space is available to contain the
formatted string.

Answer / manoj
i agree with Vignesh, and one more thing i would like to
add is,
ex:
char b[100];
sprintf( b, "Formatted data: %d / %f", i, f );
In above program, in array b string "Formatted data: %d / %
f" with proper i and f value will be stored.
it will not be printed on the output screen.

sprintf: This Writes formatted data to a character string in
memory instead of stdout
Syntax of sprintf is:
#include <stdio.h>
int sprintf (char *string, const char *format
[,item [,item]...]);
Here
String refers to the pointer to a buffer in memory where the
data is to be written. Format refers to pointer to a
character string defining the format. Each item is a
variable or expression specifying the data to write.
The value returned by sprintf is greater than or equal to
zero if the operation is successful or in other words the
number of characters written, not counting the terminating
null character is returned. And return a value less than
zero if an error occurred.
printf: Prints to stdout
Syntax for printf is:
printf format [argument]...
The only difference between sprintf() and printf() is that
sprintf() writes data into a character array, while printf()
writes data to stdout, the standard output device.

write a program to sum of its digit with using control structure or with out using loop. for ex: let the number is 25634 then answer will be=2+5+6+3+4=20

I need help with the following lab. Can anyone explain it to me on how to approach this problem. Coding would be great too !!! No busy waiting allowed. Remember that Java monitors are 'signal and continue'. The input data is called the database (DB). In this problem, it consists of a single variable initialized in the main thread, to contain the current time of day in HH:MM:SS:mmm format (mmm is milliseconds) truncated to 3 digits. Threads follow these rules: 1. Readers may all attempt to read at the same time, but NOT if a writer is writing (i.e.; the writer is in the monitor. 2. Writing is exclusive (only 1 writer at a time, no readers while writing). 3. Options: (to be specified by instructor) a. Readers have absolute priority over writers. b. Writers have absolute priority over readers c. When a reader arrives and a writer is waiting, the reader is suspended behind the writer instead of being admitted immediately. Thus, a writer waits for readers that were running when it arrived, but does not to wait for new readers. You may program this in C++ or Java. There are 4 controlling input values: 1. r – number of readers 2. w – number of writers 3. R – delay for a reader to restart 4. W – delay for a writer to restart Create the following program consisting of 1 main process (your main program) with n threads: 1. The main thread: a. Creates the 'n' threads needed. Of these, r of them are readers and w of them are writers. Starts all readers and writers. b. Waits for all 'n' threads to complete. You may use any method to detect when they are all complete. c. Prints out the resulting outputs from the threads. 2. Threads: a. When a thread starts to run, it immediately tries to enter the monitor. b. A reader thread reads the DB, outputs the exact message below, then exits: >>> DB value read =: HH:MM:SS:mmm by reader number: rr where the underlined text is replaced with actual data. c. A writer thread updates the DB with a new value (from the system time), outputs the exact message below, then exits: *** DB value set to: HH:MM:SS:mmm by writer number: ww where the underlined text is replaced with actual data. d. Each thread accesses the data a total of 10 times, exiting, then re-entering the monitor after each access. Hints: 1. File access *might* not be thread-safe, so you should be prepared to handle this. Read the documentation for the language you are using. 2. Suggested values for delays are: a. If looping, R >=1,000,000 and W>=100,000 b. If using “sleep”, then R=100 ms, W=50 ms. Additional: • Thread output is to ONE file used by ALL threads (so you need to synchronize access to it). • Readers must provide sufficient delay that results are useful (delay by R before re-trying). R is another input value. • Writers must also delay. Delay by W, updating the DB each time. W is an input. • Test your program with AT LEAST TWO different sets of values for r and w (#s of readers and writers) plus this set: r = 4, w=2. Basic operation of a thread: attempt to enter the monitor. If unsuccessful, you get put on a queue. When you get in, read or write the data (depending on type of thread), exit the monitor, wait the required delay amount, then try again. Repeat 10 times.
