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 regular polygonProperties of equilateral triangle are −3 sides of equal lengthInterior angles of same degree which is 60IncircleIncircle is the circle that lies inside the triangle which means the center of circle is same as of triangle as shown in the figure below. The center of incircle is known as incenter and radius is known as inradius.Given below is the figure of Incircle of ... Read More

Given with certain values the program will develop an EMI calculator to generate the needed output. EMI stands for Equated Monthly Installment. So this calculator will generate monthly EMI amount for the user.ExampleInput-: principal = 2000    rate = 5    time = 4 Output-: Monthly EMI is= 46.058037The formula used in the below program is −EMI : (P*R*(1+R)T)/(((1+R)T)-1)where, P indicates loan amount or the Principal amount.R indicates interest rate per monthT indicates loan time period in yearApproach used below is as followsInput principal, rate of interest and time in float variableApply the formula to calculate the EMI amountPrint the ...

Given with n nodes the task is to print the nth node from the end of a linked list. The program must not change the order of nodes in a list instead it should only print the nth node from the last of a linked list.ExampleInput -: 10 20 30 40 50 60    N=3 Output -: 40In the above example, starting from first node the nodes till count-n nodes are traversed i.e 10, 20 30, 40, 50, 60 and so the third node from the last is 40.Instead of traversing the entire list this efficient approach can be followed ...

Given with n nodes the task is to print the product of alternate node in a linked list. The program must only print the product of alternate nodes without actually changing the locations of the nodes.ExampleInput -: 10 20 30 40 50 60 Output -: 15000In the above example, starting from first node which is 10 alternate nodes are 10, 30, 50 and their product is 10*30*50 = 15000.In the above diagram, blue coloured nodes are the alternate nodes, if we start from first node and red coloured nodes are non considerable nodes.Approach used below is as followsTake a temporary ...

C programming language can be used to find the details of the Internet connection of the system. Now, let’s learn about the basics terms that we need in this problem.IP Address − IP Address stands for Internet Protocol address. An IP address is a fixed numerical identification number that is associated with each device. IP address allows communication of your device using IP address over the internet.Subnet Mask − A 32-bit component of the IP address. The subnet mask differentiates the network component of IP address into two parts of the IP address. One being network address and other being ... Read More

A stack is a data structure that stores elements. There are two operations on the stack. push that adds a new element to the stack. pop that removes an element from the stack.The stack can grow upward and downward according to the nature of the program that uses it. The program to find the direction of the growth of stack in a program.AlgorithmStep 1: Create a local variable in the main function. Step 2: Create a function that with a local variable. Step 3: Call the function from the main function. And then compare the local variables of in both ... Read More

In the C programming language, the programmer can excess the files and read and write content in them.A file is a simple memory block that can store information, here we are concerned with text only.In this program, we will compare two files and report mismatches that occur. These files are almost identical but may have some characters that are different. Also, the program will return the line and position of the file at which the first mismatch occurs.AlgorithmStep 1: Open both the file with pointer at the starting. Step 2: Fetch data from file as characters one by one. Step ... Read More

In Programing when a program malfunction and runs unusually in the terminal compiler the programmer has the power to explicitly stop the program from running. For explicitly stopping the program, the user must know the right keyboard shortcut that is needed to be pressed.To terminate the execution of a block of code, there are two types of keyboard shortcuts used.Ctrl+c − It is used to stop the execution of the program, it take a bit of time to complete the i/o operations and then suspends the execution. It sends a SIGINT signal to the process which gets terminated. In some ... Read More

An algorithm is a set of instructions that are performed in order to solve the given problem. Here, we will discuss the reversal algorithm for array rotation and create a program for a reversal algorithm.Now, let's get to some terms that we need to know to solve this problem −Array − A container of elements of the same data type. The size (number of elements) of the array is fixed at the time of the declaration of the array.Array rotation − Rotating an array is changing the order of the elements of the array. Increasing the index of the element ... Read More

A circle is a closed figure. All the points of the circle are equidistant from a point that lies inside in circle. The point at the center is known as the center of the circle. The distance of points from the center is known as the radius.The area is the quantitative representation of the span of the dimensions of a closed figure.The area of circle is the area enclosed inside the dimensions of a circle.The formula for calculating the area of a circle, Area = π*r*rTo calculate the area we are given the radius of the circle as input and ...
