Program to find Sum of a Series a^1/1! + a^2/2! + a^3/3! + a^4/4! +.......+ a^n/n! in C++
In this problem, we are given two numbers a and n. Our task is to create a program to find Sum of a Series a^1/1! + a^2/2! + a^3/3! + a^4/4! +…….+ a^n/n! in C++.Problem description − The problem is to find the sum of the given series using the given values of a and n. The series is a special series in which each term is the multiple of the last term with a/i, i -> 1 to n.Let’s take an example to understand the problemInputa = 3, n = 4Output15.375Explanationsum of series is(3^1)/1! + (3^2)/2! + (3^3)/3! + ...
Read MoreProgram to find sum of elements in a given array in C++
In this problem, we are given an array arr[] of n integer values. Our task is to create a Program to find sum of elements in a given array in C++.Program Description − For the given array, we will add up all elements and return the sum.Let’s take an example to understand the problemInputarr[] = {3, 1, 7, 2, 9, 10}Output32ExplanationSum = 3 + 1 + 7 + 2 + 9 + 10 = 32Solution ApproachTo find the sum of elements of the array, we will traverse the array and extract each element of the array and add them to ...
Read MoreProgram to find sum of first n natural numbers in C++
In this tutorial, we will be discussing a program to find sum of first n natural numbers.For this we will be provided with an integer n. Our task is to add up, find the sum of the first n natural numbers and print it out.Example#include using namespace std; //returning sum of first n natural numbers int findSum(int n) { int sum = 0; for (int x=1; x
Read MoreProgram to find sum of harmonic series in C++
In this problem, we are given three numbers a, d, and n. Our task is to create a program to find sum of harmonic series in C++.Harmonic progression is a series whose inverse will be an arithmetic progression. I.e. if for a harmonic progression A1, A2, A3.. An, there is an arithmetic progression 1/A1, 1/A2, 1/A3.So, a general HP is1/a, 1/(a+d), 1/(a+2d), … 1/(a + nd)Where 1/a is the first term. And d is the common difference of the reversed AP.Problem Description − Here, we will be given the first term a, common difference d, and the number of terms ...

In this problem, we are given a number n. Our task is to create a program to find sum of series 1 + 1/2 + 1/3 + 1/4 + .. + 1/n in C++.Code description − Here, we will find the sum of the series 1 + 1/2 + 1/3 + 1/4 + .. + 1/n till nth term. The series is a harmonic progression series.Harmonic progression is a series whose inverse will be an arithmetic progression. I.e. if for a harmonic progression A1, A2, A3... An, there is an arithmetic progression 1/A1, 1/A2, 1/A3.First, let’s take an example to ...
Read MoreProgram to find the angles of a quadrilateral in C++
In this problem, we are given a value d, which is the common difference of AP. This AP is all the angles of a quadrilateral. Our task is to create a program to find the angles of a quadrilateral in C++.Problem Description − Here, the angles of the quadrilateral are in the form of an AP with common difference d. And we need to find the angles.Let’s take an example to understand the problemInputd = 15Output67.5, 82.5, 97.5, 112.5ExplanationFirst angle is x Second angle is x + 15 Third angle is x + 30 Four angle is x + 45Sum ...
Read MoreProgram to find Prime Numbers Between given Interval in C++
In this tutorial, we will be discussing a program to find prime numbers between given intervals.For this we would be provided with two integers. Our task is to find the prime numbers in that particular range.Example#include using namespace std; int main() { int a, b, i, j, flag; //getting lower range a = 3; //getting upper range b = 12; cout
Read MoreProgram to find remainder when large number is divided by 11 in C++
In this problem, we are given a string num which is a large number. Our task is to create a program to find remainder when large number is divided by 11 in C++.Problem Description − We need to find the remainder when the number defined by the string is divided by 11.Let’s take an example to understand the problemInputnum = “43212981843718452”Output7Solution ApproachTo find the remainder, we obviously need to divide the number. But dividing huge number is a complex process so to ease up the process, we will divide digit by digit. And store the remainder that follows. This process ...
Read MoreProgram to find remainder when large number is divided by r in C++
In this problem, we are given a string num which is a large number and an integer R. Our task is to create a program to find remainder when large number is divided by r in C++.Problem Description − We need to find the remainder when the number defined by the string is divided by r which is a two-digit number.Let’s take an example to understand the problemInputnum = “123423450942121” r = 54Output7Solution ApproachTo find the remainder, we obviously need to divide the number. But dividing huge numbers is a complex process so to ease up the process, we will ...
Read MoreProgram to find remainder without using modulo or % operator in C++
In this problem, we are given two numbers, N and D. Our task is to create a Program to find remainder without using modulo or % operator in C++.Problem description − We need to find the remainder that will be left after dividing the number N by D. But we cannot use the modulo or % operator for this.Let’s take an example to understand the problemInputN = 53 D = 3Output2Solution ApproachTo find the remainder, a simple approach is to find the number less than N which is the multiple of D. And the substrate the number from N. To ...
