Apply the # flag to the %o, %x, %e, and %f format specifiers. If you want to display the hexadecimal number with a 0x prefix, then precede the %x specifier with #.Preceding the %x specifier with a #, the hexadecimal number will be printed with a 0x prefix.Let us see an example wherein $e is used. It includes a decimal point, even if the decimal digits are not present −Example Live Demoimport java.util.Formatter; public class Demo { public static void main(String args[]) { Formatter f = new Formatter(); System.out.println(f.format("%#e", 5F)); } }Output5.000000e+00
To cut only the first character, use the substr() function with UPDATE command. The syntax is as follows.UPDATE yourTableName set yourColumnName=substr(yourColumnName, 2);To understand the above syntax, let us first create a table. The query to create a table is as follows.mysql> create table CutStringDemo -> ( -> Value varchar(100) -> ); Query OK, 0 rows affected (0.66 sec)Now you can insert some records in the table using insert command. The query is as follows.mysql> insert into CutStringDemo values(', 12, 3456'); Query OK, 1 row affected (0.14 sec) mysql> insert into CutStringDemo values(', 23, 9867'); Query OK, 1 row affected ...

A rocket can be an aircraft, spacecraft or a missile which is propelled by a rocket engine. A rocket engine works on the principle of Newton's Third law, that is, for every action, there is an equivalent and opposite reaction. Rocket propellant is the fuel which burns and produces thrust to propel the rocket.The propellants are usually fueled together with the oxidants. Oxidants are required to burn the fuel efficiently. Thus the chemical reaction in the combustion chamber produces the required energy for thrust.The propellant is burnt in a controlled manner in the combustion chamber of the rocket engine and ...

The query to insert records in the table is as follows −mysql> insert into IncrementBy1 values(100, 'John', 30); Query OK, 1 row affected (0.17 sec) mysql> insert ... Read More
To detect swipe in scrollView we will need to make use of some tricks as scroll view does not natively give the directions of scroll made on it. We’ll see this with help of an example.Create an empty project, add scroll view to the view as per your requirement.Give them constraint as required in the application.From the object library, drag and drop a swipe gesture recognizer right above the Scroll View.Select the gesture recognizer, go to its attribute inspector and from there, select the swipe option and set the value as “up”.When you do this, now your gesture recognizer can ...

The minimum field width specifier is what you include between % and the format conversion code.To include a 0 before the field width specifier, pad with 0's. An integer between the % sign and the format conversion code acts as a minimum field width specifier.Let us see an example −Example Live Demoimport java.util.Formatter; public class Demo { public static void main(String args[]) { Formatter f = new Formatter(); System.out.println(f.format("%08d", 697)); f = new Formatter(); System.out.println(f.format("%10d", 9878)); f = new Formatter(); System.out.println(f.format("%06d", 697)); } }Output00000697 9878 000697
Now let us see a program of Intel 8085 Microprocessor. This program will find the square root of a number.Problem StatementWrite an assembly language program to find the square root of a number in L and store the result at location 8100HDiscussionHere we are using division method for finding square root of a number. As we know there is no division operation in 8085, so we are creating division subroutine.Let N is the number.X = √NX2 = NX2 + X2 = N + X22X2 = N + X2X2 = (N + X2)/2X =((N + X2)/X)/2XNew=(N / X + X)/2If X ...

One of the major concern of all IT companies in the security of there data. Multiple hashing techniques are there to project and check our data.What is HashHash is a function which takes variable length sequence of bytes as input and converts it to a fixed length sequence. However, to get your original data(input bytes) back is not easy. For example, x is your input and f is the f is the hashing function, then calculating f(x) is quick and easy but trying to obtain x again is a very time-consuming job.The return value from a hash function is called ...
