C++ program to find the side of the Octagon inscribed within the square
In this tutorial, we will be discussing a program to find the side of the octagon inscribed within a given square.For this, we will be given with the side of a square and our task is to find the side of the largest octagon that can be inscribed in it.Finding the relation between the sides of the square and the octagon, we find the formula for the side of the octagonside of square/(√2 + 1)Example#include using namespace std; //calculating the side of the octagon float calc_oside(float a) { if (a < 0) return -1; ...

In this tutorial, we will be discussing a program to find the smallest element among the provided three elements.We will be provided with three elements/ integers and our task is to compare them and find the smallest element/ integer among them.Example#include using namespace std; int main() { int a = 45, b = 72, c = 10; if (a
Read MoreC++ program to find the Sum of each Row and each Column of a Matrix
In this tutorial, we will be discussing a program to find the sum of each row and each column for a given matrix.For this, we will be given with a say A*B matrix. Our task is to traverse through all the elements of the matrix and find the sum of each row and each column of the matrix.Example#include using namespace std; #define m 7 #define n 6 //calculating sum of each row void calc_rsum(int arr[m][n]){ int i,j,sum = 0; for (i = 0; i < 4; ++i) { for (j = 0; j < 4; ++j) { sum = sum + arr[i][j]; } cout
Read MoreC++ program to find the sum of the series (1*1) + (2*2) + (3*3) + (4*4) + (5*5) + ... + (n*n)
In this tutorial, we will be discussing a program to find the sum of the given series (1*1) + (2*2) + (3*3) + (4*4) + (5*5) + … + (n*n).For this, we will be given with the value of n and our task is to add up every term starting from the first one to find the sum of the given series.Example#include using namespace std; //calculating the sum of the series int calc_sum(int n) { int i; int sum = 0; for (i = 1; i
Read MoreC++ program to find the sum of the series (1/a + 2/a^2 + 3/a^3 + ... + n/a^n)
In this tutorial, we will be discussing a program to find the sum of the given series (1/a + 2/a^2 + 3/a^3 + … + n/a^n).For this, we will be given with the value of n and our task is to add up every term starting from the first one to find the sum of the given series.Example#include #include using namespace std; //calculating the sum of the series float calc_sum(int a, int n) { int i; float sum = 0; for (i = 1; i
Read MoreC++ Program to find the sum of the series 23+ 45+ 75+..... upto N terms
In this tutorial, we will be discussing a program to find the sum of the given series 23+ 45+ 75+….. upto N terms.For this, we will be given with the value of N and our task is to add up every term starting from the first one to find the sum of the given series.After solving this, we get the formula for the sum of the series;Sn = (2n(n+1)(4n+17)+54n)/6Example#include using namespace std; //calculating the sum of the series int calc_sum(int N) { int i; int sum = (2 * N * (N + 1) * (4 * ...
Read MoreC++ program to find the sum of the series 1 + 1/2^2 + 1/3^3 + .....+ 1/n^n
In this tutorial, we will be discussing a program to find the sum of the given series 1 + 1/2^2 + 1/3^3 + …..+ 1/n^n.For this, we will be given with the value of n and our task is to add up every term starting from the first one to find the sum of the given series.Example#include #include using namespace std; //calculating the sum of the series double calc_sum(int n) { int i; double sum = 0.0, ser; for (i = 1; i
