C program to find decagon numbers?
Decagonal numbers are graphics derived using the concepts of triangular numbers and square numbers. Extensions of this number pattern are created using non-rotationally symmetric numbers. This number for nested decagons is given by the number of points in the number of nested decagons created.
For example, for the 3rd decagon number, 3 decagon numbers are nested in iX times the number of sides of the decagon. As shown in the picture-
The side of the first external figure = 30
The side of the second external figure = 20
Inner picture Edges in = 10
All shared edges = 6 2
Total = 30 20 10-(6 2) = 52
This result is generalized using the formula 4n2 - 3n .
This gives the decagonal number of n

C++ program to compare the lexicographic order of two strings
Sep 04, 2023 pm 05:13 PM
Lexicographic string comparison means that strings are compared in dictionary order. For example, if there are two strings 'apple' and 'appeal', the first string will come last because the first three characters of 'app' are the same. Then for the first string the character is 'l' and in the second string the fourth character is 'e'. Since 'e' is shorter than 'l', it will come first if we sort lexicographically. Strings are compared lexicographically before being arranged. In this article, we will see different techniques for lexicographically comparing two strings using C++. Using the compare() function in C++ strings The C++string object has a compare()
Where is the place where the candlelight shines in Destiny Ark?
Mar 20, 2024 pm 05:46 PM
The opening of a new version of the new map of Ark of Destiny also has a new reputation mission. In addition to the Rowan map, there is also a daily mission on the Wisdom Island. The prerequisite mission is started from Belongnan. Many friends have achieved the goal of "finding the right map". There is no guidance for this link "The place where the candlelight shines". I am also curious about the specific location. Here is the guide for this task! The guide for the mission of Destiny Ark to find the place where the candlelight shines is in the room in the Wisdom Island. There is also a corridor in the hall, which can lead to the basement. When you walk in, you can see the location of the subsequent tasks, as shown in the picture:
C++ program to find the value of the inverse hyperbolic sine function taking a given value as argument
Sep 17, 2023 am 10:49 AM
Hyperbolic functions are defined using hyperbolas instead of circles and are equivalent to ordinary trigonometric functions. It returns the ratio parameter in the hyperbolic sine function from the supplied angle in radians. But do the opposite, or in other words. If we want to calculate an angle from a hyperbolic sine, we need an inverse hyperbolic trigonometric operation like the hyperbolic inverse sine operation. This course will demonstrate how to use the hyperbolic inverse sine (asinh) function in C++ to calculate angles using the hyperbolic sine value in radians. The hyperbolic arcsine operation follows the following formula -$$\mathrm{sinh^{-1}x\:=\:In(x\:+\:\sqrt{x^2\:+\:1})}, Where\:In\:is\:natural logarithm\:(log_e\:k)
C program to find length of linked list
Sep 07, 2023 pm 07:33 PM
Linked lists use dynamic memory allocation, i.e. they grow and shrink accordingly. They are defined as collections of nodes. Here, a node has two parts, data and links. The representation of data, links and linked lists is as follows - Types of linked lists There are four types of linked lists, as follows: - Single linked list/Singly linked list Double/Doubly linked list Circular single linked list Circular double linked list We use the recursive method to find the length of the linked list The logic is -intlength(node *temp){ if(temp==NULL) returnl; else{&n
C++ program to print dictionary
Sep 11, 2023 am 10:33 AM
A map is a special type of container in C++ in which each element is a pair of two values, namely a key value and a map value. The key value is used to index each item, and the mapped value is the value associated with the key. Regardless of whether the mapped value is unique, the key is always unique. To print map elements in C++ we have to use iterator. An element in a set of items is indicated by an iterator object. Iterators are primarily used with arrays and other types of containers (such as vectors), and they have a specific set of operations that can be used to identify specific elements within a specific range. Iterators can be incremented or decremented to reference different elements present in a range or container. The iterator points to the memory location of a specific element in the range. Printing a map in C++ using iterators First, let's look at how to define
C program uses rename() function to change file name
Sep 21, 2023 pm 10:01 PM
The rename function changes a file or directory from its old name to its new name. This operation is similar to the move operation. So we can also use this rename function to move files. This function exists in the stdio.h library header file. The syntax of the rename function is as follows: intrename(constchar*oldname,constchar*newname); The function of the rename() function accepts two parameters. One is oldname and the other is newname. Both parameters are pointers to constant characters that define the old and new names of the file. Returns zero if the file was renamed successfully; otherwise, returns a nonzero integer. During a rename operation
C program to implement Euclidean algorithm
Sep 17, 2023 pm 12:41 PM
The problem implements Euclidean's algorithm to find the greatest common divisor (GCD) and least common multiple (LCM) of two integers and outputs the results with a given integer. Solution The solution to implement Euclidean algorithm to find the greatest common divisor (GCD) and least common multiple (LCM) of two integers is as follows - the logic of finding GCD and LCM is as follows - if (firstno*secondno!=0){ gcd= gcd_rec(firstno,secondno); printf("TheGCDof%dand%dis%d",
