C Program for Armstrong Numbers
We are given a task where we have to check a number n entered by the user, whether it’s Armstrong or not.An Armstrong number is when the sum of all the digits power by the number of digits or we can say order of digits n, is same as the digit.So below is a simple representation how to find the Armstrong number −Formula −wxyz…. = pow(w, n) +pow(x, n) + pow(y, n) + pow(z, n) + …..AlgorithmSTART Step 1-> Declare a function to find the value after power operation on the number int power(int a, int b) ...
Read MoreProgram for Area Of Square in C++
We are given with a side of a rectangle and our task is to print the area of the square from that side.Square is 2-D plain figure which have 4 sides and forms 4 angles of 90degree each and all the sides are of equal shape. In other words we can say that the square is a form of rectangle with equal sides.Given below is representation of a square −The Area of square is Side x SideExampleInput: 6 Output: 36 As the side is 6 so the output is 6*6=36 Input: 12 Output: 144AlgorithmSTART Step 1-> Declare a function ...
Read MoreC Program for Area And Perimeter Of Rectangle
Given a length and breadth of a rectangle we have to find its area and Perimeter.Rectangle is 2-D figure containing four sides and four angles of 90 degree each. All the sides of rectangle are not equal only the opposite sides of a rectangle are equal. The diagonals in a rectangle also are of the same length.Below is a diagrammatic representation of rectangle.Here A represents the breadth and B represents length of the rectangle.To find the Area of a rectangle the formula is: Length x BreadthAnd Perimeter of a rectangle is − 2 x (Length+Breadth).ExamplesInput: 20 30 Output: area of rectangle ...
Read MoreC Program for n-th odd number
Given a number N we have to find the N-th odd number.Odd numbers are the numbers which are not completely divided by 2 and their remainder is not zero. Like 1, 3, 5, 7, 9, ….If we closely observe the list of even numbers we can also represent them as(2*1)-1=1, (2*2)-1=3, ( 2*3)-1=5, (2*4)-1=7, ….(2*N)-1.So, to solve the problem we can simply multiply the number N with 2 and subtract 1 from the result, that makes up an odd number.ExamplesInput: 4 Output: 7 The 4th odd number is 1, 3, 5, 7.. Input: 10 Output: 19AlgorithmSTART STEP 1 -> ...

Given a number N we have to find the N-th even number.Even numbers are the numbers which are completely divided by 2 and their remainder is zero. Like 2, 4, 6, 8, 10, ….If we closely observe the list of even numbers we can also represent them as2*1=2, 2*2=4, 2*3=6, 2*4=8, ….2*N.So, to solve the problem we can simply multiply the number N with 2, so the result will be the number which is divisible by 2, i.e. the even number.ExampleInput: n = 4 Output: 8 The first 4 even numbers will be 2, 4, 6, 8, .. Input: ...
Read MoreProgram to check if N is a Pentagonal Number in C++
Given with a number N the task is to check whether the number is a pentagonal number or not. Numbers that can be arranged to form a pentagon is a pentagonal number as these numbers can be used as points to form a pentagon. For example, some of pentagonal numbers are 1, 5, 12, 22, 35, 51....We can use formula to check whether the number is a pentagonal number or not$$p(n)=\frac{\text{3}*n^2-n}{\text{2}}$$Where, n is the number of points pentagonal will haveExampleInput-: n=22 Output-: 22 is pentagonal number Input-: n=23 Output-: 23 is not a pentagonal numberAlgorithmStart Step 1 -> declare function ...
Read MoreC++ Program to Convert Km/hr to miles/hr and vice versa
If input is in km/hr convert it to miles/hr else input will be in miles/hr convert it to km/hr. There are formulas that can be used for this conversion.Conversion Formulas −1 kilo-metre = 0.621371 miles 1 miles = 1.60934 Kilo-meterExampleInput-: kmph= 50.00 Mph = 10.00 Output-: speed in m/ph is 31.07 speed in km/ph is 16.0934AlgorithmStart Step 1 -> Declare function to convert km/ph to m/ph double km_mph(double km) return 0.6214 * km step 2 -> Declare function to convert m/ph to km/ph double m_km(double m_ph) return m_ph * 1.60934 ...
Read MoreProgram to convert speed in km/hr to m/sec and vice versa in C++
Conversion Formulas −1 km/hr = 5/18 m/sec or 0.277778 m/sec 1 m/sec = 18/5 km/hr or 3.6 km/hrExampleInput-: km = 60.00 mk = 70.00 Output-: speed in meter per second = 16.6667 speed in km per hour = 252AlgorithmStart Step 1 -> Declare function to convert km/hr into m/sec float km_m(float km) return (0.277778 * km) Step 2 -> Declare function to convert m/sec into km/hr float m_km(float mk) return (3.6 * mk) step 3 -> In main() declare variable as float km = 60.0 and float mk = ...
Read MoreProgram to Convert Radian to Degree in C
If input is in radian convert it to degree else input will be in radian convert it to degree. There are formulas that can be used for this conversion.Radian is the standard unit for measuring angles whereas the complete angle of circle is divided into 360 degree. Also, radian is the smaller value as 1 degree = 180 radians.Conversion Formulas −degree = radian * (180/pi) where, pi=3.14 or 22/7ExampleInput-: radian = 9.0 Output-: degree is : 515.92357AlgorithmStart Step 1 -> define macro as #define pi 3.14 Step 2 -> declare function for converting radian to degree double convert(double radian) ...
