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 given number of days in terms of Years, Weeks and Days in C
You are given with number of days, and the task is to convert the given number of days in terms of years, weeks and days.Let us assume the number of days in a year =365Number of year = (number of days) / 365Explanation-: number of years will be the quotient obtained by dividing the given number of days with 365Number of weeks = (number of days % 365) / 7Explanation-: number of weeks will be obtained by collecting the remainder from dividing the number of days with 365 and further dividing the result with number of days in a week ...
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 ...
Read MoreProgram to calculate area and perimeter of equilateral triangle in C++
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 ...

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 MoreC Program for FCFS Scheduling
We are given with the n number of processes i.e. P1, P2, P3, ..., Pn and their corresponding burst times. The task is to find the average waiting time and average turnaround time using FCFS CPU Scheduling algorithm.What is Waiting Time and Turnaround Time?Turnaround Time is the time interval between the submission of a process and its completion.Turnaround Time = completion of a process – submission of a processWaiting Time is the difference between turnaround time and burst timeWaiting Time = turnaround time – burst timeWhat is FCFS Scheduling?First Come, First Served (FCFS) also known as First In, First Out ...
Read MorePrint prime numbers from 1 to N in reverse order
In this article, we will learn how to print prime numbers from 1 to N in reverse order. A prime number is a number greater than 1 that has no positive divisors other than 1 and itself. Our goal is to find all prime numbers in the given range from 1 to N and then print them in reverse order. For example, given N = 20, the prime numbers between 1 and 20 are: 2, 3, 5, 7, 11, 13, 17, 19 The output should be the prime numbers printed in reverse order: 19, 17, 13, 11, 7, 5, ...

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) ...
