Program to convert given Matrix to a Diagonal Matrix in C++
Given with the matrix of size nxn the task it to convert any type of given matrix to a diagonal matrix.What is a diagonal MatrixDiagonal matrix is the nxn matrix whose all the non-diagonal elements are zero and diagonal elements can be any value.Given below is the diagram of converting non-diagonal elements to 0.$$\begin{bmatrix}1 & 2 & 3 \4 & 5 & 6 \7 & 8 & 9 \end{bmatrix}\:\rightarrow\:\begin{bmatrix}1 & 0 & 3 \0 & 5 & 0 \7 & 0 & 9 \end{bmatrix}$$The approach is to start one loop for all non-diagonal elements and another loop for diagonal elements ...
Read MoreProgram to convert KiloBytes to Bytes and Bits in C++
Given with the input as KiloBytes and the task is to convert the given input into number of bytes and bits.Bit − In computers, bit is the smallest unit represented with two integer value 0 and 1 and all the information in computer is processed as a sequence of these two digits.N-bits = 2 ^ N patterns, where N can be any integer value starting from 1.Byte − In computers, byte is represented with 8 bits. Byte is capable of holding one character to numbers ranging between 0 and 255.1 byte = 8 bitsWhich means 2 ^ 8 patterns which ...
Read MoreProgram to convert IP address to hexadecimal in C++
Given with the input as an IP address value and the task is to represent the given IP address as its hexadecimal equivalent.What is IP addressIP address or Internet protocol is a unique number to that uniquely describes your hardware connected to a network. Internet means over the network and protocol defines the set of rules and regulations that must be followed for connection. Because of IP address only it is possible for a system to communicate with another system over a network. There are two versions of IP that are −IPv4(Internet Protocol Version 4)IPv6(Internet Protocol Version 6)IP address is ...

What is Equilateral Triangle?As the name suggests, equilateral triangle is the one that have equal sides and also it have equal interior angles of 60° each. It is also known as regular triangle because it’s a regularpolygonProperties of equilateral triangle are −3 sides of equal lengthInterior angles of same degree which is 60Given below is the figure of equilateral triangleProblemGiven with the side of equilateral triangle the task is to find the area and perimeter of a triangle where area is the space occupied by the shape and perimeter is the space occupied by its boundaries.To calculate area and perimeter ...
Read MoreProgram for Volume and Surface area of Frustum of Cone in C++
What is Frustrum of cone?Frustum of a cone is formed by cutting the tip of a cone leaving lower and upper base known as frustum as shown in the figure. The upper base of frustum will have radius ‘r’, lower base will have radius ‘R’ with height ‘h’ and slant height ‘L’Given below is the figure of Frustrum of coneProblemGiven with slant height, height, upper base radius ‘r’ and lower radius ‘R’, the task is to calculate the volume and surface area of Frustum of cone.To calculate the volume and surface area of Frustum of cone there is a formulaVolume ...
Read MoreRead/Write Class Objects from/to File in C++
The iostream standard library has two methods cin, to accept input from standard input stream and cout to print output to the standard output stream. In this article we will learn how to read data from files into class objects and how to write data in class objects to files.Reading and writing data to and from files requires another standard library of C++ . The three main data types of fstream are −ifstream − represents input file stream and reads information from files.ofstream − represents output file stream and writes information to files.fstream − represents general file stream and has ...
Read MoreProgram for Fibonacci numbers in PL/SQL
Given ‘n’ numbers the task is to generate the Fibonacci numbers in PL/SQL starting from 0 to n, where the Fibonacci series of integers is in the form 0, 1, 1, 2, 3, 5, 8, 13, 21, 34 Where integers 0 (1st place) and 1 (2nd place) will have a fixed place after that, the previous two digits will be added to get the integer of the next place as shown below. 0+1=1 (3rd place) 1+1=2 (4th place) 2+1=3 (5th place) and So on. Formula Sequence F(n) ...
Read MoreCount set bits in an integer in C++
We are given an integer number let’s say, num and the task is to first calculate the binary digit of a number and then calculate the total set bits of a number. Set bits in a binary number are represented by 1. Whenever we calculate the binary number of an integer value then it is formed as the combination of 0’s and 1’s. So, the digit 1 is known as a set bit in terms of the computer. Example 1 Input − int number = 50 Output − The count ...
Read MoreProgram for Point of Intersection of Two Lines in C++
Given points A and B corresponding to line AB and points P and Q corresponding to line PQ; the task is to find the point of intersection between these two lines. Note − The points are given in 2D plane on X and Y coordinates. Here A(a1, a2), B(b1, b2) and C(c1, c2), D(d1, d2) are the coordinates which are forming two distinct lines and P(p1, p2) is the point of intersection. (just for a diagrammatic explanation of the point of intersection) How to find the point of intersection − Let’s take the above figure as − Example So ...
Read MoreJava program to convert Byte array to IP Address
In this article, we will learn to convert a byte array into an IP address using the IPAddress class in Java. This program takes a series of bytes, representing an IP address in binary form, and converts them into a standard dot-separated string representation of an IP address. We'll go through the simple steps of declaring a byte array and then converting it into a readable IP address format. What is a Byte Array? A byte comprises 8 bits and a byte array comprises contiguous bytes which store the binary information. In Java, a byte is a primitive datatype that can ...
