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; ...
Read MoreC++ program to find the smallest element among three elements
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
Read MoreMakeFile in C++ and its applications
In this tutorial, we will be discussing a program to understand MakeFile in C++ and its applications.The task is to break the entire program with MakeFile. It is usually done by making .cpp files and .h files with all the classes/functionalities and link them together.Examplemain.cpp#include #include "function.h" using namespace std; //main execution program int main(){ int num1 = 1; int num2 = 2; cout
Read MoreDraw a line in C++ graphics
In this tutorial, we will be discussing a program to draw a line in C++ graphics.To implement different shapes and sizes, animations, graphics.h library is used in C++.Example#include int main(){ int gd = DETECT, gm; initgraph(&gd, &gm, ""); line(150, 150, 450, 150); line(150, 200, 450, 200); line(150, 250, 450, 250); getch(); closegraph(); return 0; }Output
Read MoreDelete and free() in C++ Program
In this tutorial, we will be discussing a program to understand delete() and free() functions in C++.Both of these functions are primarily used for the same purpose i.e freeing up unused memory. The delete() operator is for the ones allocated using new() and free() for the ones allocated using malloc().Example#include #include int main(){ int x; int *ptr1 = &x; int *ptr2 = (int *)malloc(sizeof(int)); int *ptr3 = new int; int *ptr4 = NULL; //incorrect usage of delete delete ptr1; delete ptr2; //correct usage of delete delete ptr3; delete ptr4; getchar(); return 0; }
