Palindrome number is a number which remains same when it reverses. In C language, the user is allowed to enter any positive integer and to check, whether the given number is palindrome number or not by using the while loop.Example1Following is the C Program to find Palindrome number by using the while loop − Live Demo#include int main(){ int num, temp, rem, rev = 0; printf("enter a number:"); scanf("%d", &num); temp = num; while ( temp > 0){ rem = temp %10; rev = rev *10+ rem; ...

Here, the user has to enter the length in centimeters (cm), and then, convert the length into meters (m), and kilometer (km).1 Meter = 100 Centimeters 1 Kilometer = 100000 CentimetersAlgorithmRefer an algorithm given below to convert centimeter into meter and kilometer respectively.Step 1: Declare variables. Step 2: Enter length in cm at runtime. Step 3: Compute meter by using the formula given below. meter = centim / 100.0; Step 4: Compute kilometer by using the formula given below. kilometer = centim / 100000.0 Step 5: Print meter. Step 6: Print kilometeExample1Following is the C program to convert ... Read More
In this post, we will understand the difference between float and double data types.floatIt has a single precision.It takes 4 bytes of memory.According to IEEE, it has 32-bit precision.It is used with graphic based libraries.It improves the processing power of programs.It is simple to manage by compilers.Its value can be between 1.2E-38 to 3.4E+38.It can have a precision of up to 6 decimal places.doubleIt has a double precision.It takes 8 bytes of memory.According to IEEE, it has 64-bit precision.Its value can be between 2.3E-308 to 1.7E+308.It can have a precision of up to 15 decimal places.It is considered as the ...

ProblemFind the sum of an arithmetic progression series, where the user has to enter first number, total number of elements and the common difference.SolutionArithmetic Progression (A.P.) is a series of numbers in which the difference of any two consecutive numbers is always the same. Here, total number of elements is mentioned as Tn.Sum of A.P. Series: Sn = n/2(2a + (n – 1) d) Tn term of A.P. Series: Tn = a + (n – 1) dAlgorithmRefer an algorithm given below to find the arithmetic progression.Step 1: Declare variables. Step 2: Initialize sum=0 Step 3: Enter first number of series ...

Based on the units consumed by the user, the electricity bill is generated. If number of units consumed are more then, the rate of a unit charge will also increase.The logic applied if minimum units are consumed by the user is as follows −if (units < 50){ amt = units * 3.50; unitcharg = 25; }The logic applied if units are in between 50 to 100 is given below −else if (units
In this post, we will understand the difference between ‘new’ and ‘malloc’.newIt is present in C++, Java, and C#.It is an operator that can be used to call the constructor of the object.It can be overloaded.If it fails, an exception is thrown.It doesn’t need the ‘sizeof’ operator.It doesn’t reallocate memory.It can initialize an object when allocating memory for it.The memory allocated by ‘new’ operator can be de-allocated using ‘delete’ operator.It reduces the execution time of the application.Example#include using namespace std; int main(){ int *val = new int(10); cout Read More
In this post, we will understand the difference between the methods ‘dispose’, and ‘finalize’ in C#.DisposeThis method is defined in the IDisposable interface.It has to be invoked by the user.Whenever it is invoked, it helps free the unmanaged resources.It can be implemented whenever a close() method is present.It is declared as public method.It is quick, and instantly disposes an object.Since it performs instantaneously, it doesn’t affect performance.FinalizeIt is a method that is defined in the java.lang.object class.It is invoked by the garbage collector.It helps free the unmanaged resources just before the object is destroyed.It is implemented to manage the unmanaged ...

In this post, we will understand the differences between ‘Extends’ and ‘Implements’ keyword.ExtendsUsing this, a class can be used as a base class, and another class inherits this base class.An interface can also inherit other interfaces using this keyword.Only one superclass can be extended by a class.Any number of interfaces can be extended by an interface.It is not required for the subclass (that extends a superclass) to override all the methods in the superclass.Following is an example of the extends keyword −Exampleclass Super { ..... ..... } class Sub extends Super { ...

In this post, we will understand the difference between HashMap and LinkedHashMap in Java.HashMapIn this structure, the order of insertion is not preserved.It uses the HashTable to store maps.It extends the ‘AbstractMap’.It implements the ‘Map’ interface.This was introduced in JDK 2.0.It has a relatively low overhead.LinkedHashMapIn this structure, the order of insertion is not preserved.It uses the HashTable and Linked List to store maps.It extends the ‘Hashmap’.It implements the ‘Map’ interface.This was introduced in JDK 4.0.It has a relatively higher overhead.This is because it has to maintain the order of entries in the map structure.Read More
In order to add two complex numbers in C programming language, the user has to take two complex numbers as structure members and perform addition operation on those two numbers by creating a user-defined function.AlgorithmRefer an algorithm given below for addition of two complex numbers.Step 1: Declare struct complex with data members. Step 2: Declare name for structure and variables. Step 3: Enter real and imaginary part for first complex number at run time. Step 4: Enter real and imaginary part for second complex number at runtime Step 5: Compute addition of number1 and number2 by calling function. Go to ... Read More
