How do you clear a StringBuffer?
Set length of buffer to zero to clear a StringBufferinstance.Example:StringBuffer buf = new StringBuffer();// ... use bufferbuf.setLength(0);// buffer now has zero length
Why gets function gives a warning every time you compile a c program?
It is unsafe. In order to use gets() safely, you need to know how many characters you will be reading to ensure your character buffer is large enough: char buffer[10]; while (gets (buffer) != 0) { ...process buffer... } The above code has undefined behaviour when the number of characters read is 10 or more (you need one character for the null-terminator). This is because the character buffer, str, decays to a pointer (referencing &str[0]) and the function, gets(), cannot determine the number of characters in a buffer by its pointer alone. The gets() function was dropped from the C standard in 2011, however some implementations still include it. To avoid the warning, use the fgets() function instead. This allows you to specify the length of your buffer and (when used correctly) prevents buffer overflow. char buffer[10]; while (fgets (buffer, 10, stdin) != 0) { ...process buffer... }
What is difference between single double and circular buffer?
single buffer : you read and write on the same buffer, can be messy if both reading and writing take place at the same time.double buffer : you read one buffer and you write the other one. When both reading and writing are complete, the buffers are swapped. It solves the problem of simultaneous reading and writing but requires synchronization.circular buffer : this a buffer with two pointer : read and write. If both pointers are equal, the buffer is empty.For each write operation, the write pointer advances and each time data is read back, the read pointer advances. It is circular because when a pointer reaches the end, it wraps back to the beginning.It may be used to implement a queue which allows simultaneous reading and writing without synchronization as long as the buffer is not full.A double buffer is basically a circular buffer of size 2 and a single buffer is basically a circular buffer of size 1.
What do you mean by buffer in micro processor?
A buffer is merely a temporary storage used in conjunction with computation.
Why scanf functions is not used to read a line of text?
Because it is not safe. Scanf puts the data into a buffer. There is no size checking so the data may be larger than the buffer causing a buffer overrun with undefined (usually bad but always undesirable) behavior.
What is the collective noun for attackers?
Appropriate collective nouns for attackers are a band of attackers, a gang of attackers, a group of attackers, etc.
Which bjt transistor amplifier can be used as a voltage buffer?
the common collector can use as voltage buffer
When was Attackers created?
Attackers was created in 1996.
What is the use of buffer?
To maintain constant the pH of a solution.
How do you use buffer in a sentence?
You didn't say which meaning you want to use for this word. A buffer can be a barrier which lessens or absorbs a shock. The airbag acts as a buffer in case of an accident. She was the buffer between them, and kept the argument from getting out of hand. Buffer can also mean a chemical substance which minimizes the acidity of a substance. I need a bottle of buffered aspirin; the buffer keeps it from upsetting your stomach. Buffer can also be a verb meaning to do either of the above. The neutral zone between the two countries buffered their rivalry. That substance buffers the chemicals.
What is the area normally covered by water when a river overflows its banks?
The area normally covered by water when a river overflows its banks is called the floodplain. This is the flat, low-lying area surrounding the river that is susceptible to flooding during periods of high water flow. Floodplains serve as a natural buffer to absorb excess water and reduce the risk of damage to nearby communities.
How do you increase buffer capacity?
Increase the concentration of salt and acid or base. If you are not suppose to increase concentration use more volume of buffer.
Why did the Indians use weapons?
To hunt and defend against attackers. Later in war against the "Whites"
Is it true apatosaurus crushed its attackers with forelegs?
Personally i think that the apatosaurus could not crush it attackers with its forelegs because the attackers would have to be miniscule.
What are brand names for buffer-in?
Some brand names for buffer-in solutions include Tris Buffer, Phosphate Buffer, HEPES Buffer, and Bicine Buffer.
How do you make a borate buffer?
To make a borate buffer, mix boric acid with sodium hydroxide or sodium borate in water. Adjust the pH of the buffer to your desired range by adding more acid or base. Remember to use a pH meter to accurately measure the pH of the buffer.
How do you calculate buffer in a chemical solution?
To calculate the buffer capacity of a chemical solution, you can use the formula: Buffer capacity (moles of added acid or base) / (change in pH). This formula helps determine the ability of a buffer solution to resist changes in pH when an acid or base is added.
