Program to find root of an equations using secant method in C++
In this tutorial, we will be discussing a program to find the root of an equation using secant method.For this we will be provided with an equation. Our task is to find the roots of that equation using the iterative secant method.Example#include using namespace std; float f(float x) { float f = pow(x, 3) + x - 1; return f; } void secant(float x1, float x2, float E) { float n = 0, xm, x0, c; if (f(x1) * f(x2) < 0) { do { //calculating the intermediate ...
Read MoreProgram to find second most frequent character in C++
In this problem, we are given string str. Our task is to create a Program to find second most frequent character in C++.Let’s take an example to understand the problemInputstr = “abaacabcba”Output‘b’Solution ApproachTo find the character that is second most frequent in the string. We need to maintain a count array chatCount that is used to store the frequency of each character in the string. And then using the array we will find the character with max and secondMax frequency in the array. And display the second most frequent character.Program to illustrate the working of our solutionExample#include #include ...

In this problem, we are given string str. Our task is to create a program to find Smallest and Largest Word in a String in C++.Problem Description − Here, we have a string we need to find the word whose length is maximum and minimum out of all words in the string. The word is separated using white spaces or null(\0) characters.Let’s take an example to understand the problemInputstr = “Learn Programming at TutorialsPoint”Outputsmallest word = at largest word = TutorialspointSolution ApproachTo find the smallest and largest word, we will find the length of each word by using two indexes, ...
Read MoreProgram to find the Area and Perimeter of a Semicircle in C++
In this problem, we are given a value that denotes the radius of a semicircle. Our task is to create a program to find the Area and Perimeter of a Semicircle in C++.SemiCircle is a closed figure that is half of a circle.Let’s take an example to understand the problem, InputR = 5Outputarea = 39.25 perimeter = 15.7Solution ApproachTo solve the problem, we will use the mathematical formula for the area and perimeter of a semi-circle which is derived by dividing the area of circle by 2.Area of semicircle, A= $½(\prod^*a^2)=1.571^*a^2$Perimeter of semicircle, P =(π*a)Area of semicircle, area = $½(π^*a^2)$Program ...
Read MoreProgram to find the Area and Volume of Icosahedron in C++
In this problem, we are given a value that denotes the side of an icosahedron. Our task is to create a program to find the Area and Volume of Icosahedron in C++.Icosahedron is a regular 30 sided polyhedron. It has 20 equilateral triangles of the same side. There are only 12 vertices of this polyhedron.Dashed lines are for the edges that are behind the visible surface.Let’s take an example to understand the problem, Inputa = 4Program to illustrate the working of our solution, Example#include using namespace std; float calcIcoSArea(float a) { return (8.660 * a * a); } ...
Read MoreProgram to find the Area of a Parallelogram in C++
In this problem, we are given two values that denote the base and height of a parallelogram. Our task is to create a Program to find the Area of a Parallelogram in C++.Parallelogram is a four side closed figure that has opposite sides equal and parallel to each other.Let’s take an example to understand the problem, InputB = 20, H = 15Output300ExplanationArea of parallelogram = B * H = 20 * 15 = 300Solution ApproachTo solve the problem, we will use the geometrical formula for area of parallelogram, Area = base * height.Program to illustrate the working of our solution, ...

In this problem, we are given a number n that denotes that side of the pentagon. Our task is to create a program to find the Area of a Pentagon in C++.Pentagon is a five-sided geometric figure.Regular pentagon is a pentagon with all five sides and angles equal.Let’s take an example to understand the problem,Inputa = 7Output84.3Program to illustrate the working of our solution,Example#include using namespace std; float calcpentagonArea(int a){ return ( ((6.8819)*a*a)/4); } int main() { int a = 7; cout
Read MoreProgram to find the Break Even Point in C++
In this problem, we are given the three variables that denote total monthly expenditure (E), selling price (S) of the product, overhead maintenance (M) on each product. Our task is to create a program to find the Break Even Point in C++.Break-Even Point is the total number of products that are required to be sold so that there should not be any loss or profit for the seller.Problem Description − We need to find the total no. of products to be sold to make sure there is no loss.Let’s take an example to understand the problem, InputE = 2400, S ...
Read MoreProgram to find the Centroid of the Triangle in C++
In this problem, we are given a 2D array that denotes coordinates of three vertices of the triangle. Our task is to create a program to find the Centroid of the Triangle in C++.Centroid of a triangle is the point at which the three medians of the triangles intersect.Median of a triangle is the line that connects the vertex of the triangle with the center point of the line opposite to it.Let’s take an example to understand the problem, Input(-3, 1), (1.5, 0), (-3, -4)Output(-3.5, -1)ExplanationCentroid (x, y) = ((-3+2.5-3)/3, (1 + 0 - 4)/3) = (-3.5, -1)Solution ApproachFor solving ...
