Basic Graphic Programming in C++
C++ programming language is a versatile programming language. Using C++ you can create low end graphics too i.e. creating basic shapes and words with stylish fonts and adding colors to them can be done using c++.Graphic programming can be done in c++ using your terminal or command prompt or you can download DevC++ compiler to create graphic programs.For terminal you need to add the graphics.h libraray to you GCC compiler. For this you will have type in the following commands.>sudo apt-get install build-essential >sudo apt-get install libsdl-image1.2 libsdl-image1.2-dev guile-2.0 \ guile-2.0-dev libsdl1.2debian libart-2.0-dev libaudiofile-dev \ libesd0-dev libdirectfb-dev libdirectfb-extra libfreetype6-dev \ ...
Read MoreC++ program to find the Radius of the incircle of the triangle
In this tutorial, we will be discussing a program to find the radius of the incircle of a given triangle.For this, we will be provided with the sides of a particular triangle and our task is to find the radius of the incircle in that triangle.The formula for finding the radius of incircle isarea of the triangle/half perimeter of the triangleExample#include using namespace std; //calculating the radius of incircle float calc_radius(float a, float b, float c) { if (a < 0 || b < 0 || c < 0) return -1; //half perimeter of ...
Read MoreC++ program to find the quantity after mixture replacement
In this tutorial, we will be discussing a program to find the quantity of milk left after mixture replacement.Let us suppose we have X litres of milk. From that, Y litres of milk is replaced with Y litres of water itself. This same procedure is done again and again Z number of times. Our task is to find the final amount of milk left in the container.Finding the relation among the values between the repetitive operations, we find the formula for finding the amount of milk after Z number of operations to beamount left = ((X-Y)/X)Z*XExample#include using namespace std; ...
Read MoreC++ Program to calculate the value of sin(x) and cos(x)
Given with the input as angles and the task is to calculate the value of sin(x) and cos(x) corresponding to the given angle and display the resultFor Sin(x)Sin(x) is a trigonometric function which is used to calculate the value of x angle.Formula$$\sin (x) = \displaystyle\sum\limits_{k=0}^\infty \frac{(-1)^{k}}{(2k+1)!}x^{2k+1}$$For Cos(x)Cos(x) is a trigonometric function which is used to calculate the value of x angle.Formula$$\cos (x) = \displaystyle\sum\limits_{k=0}^\infty \frac{(-1)^{k}}{(2k)!}x^{2k}$$Approach used in the below program is as follows −Input the value of x angle for sin(x) and cos(x)Apply the formulas given for sin(x) and cos(x)Print the resultALGORITHMSTART Step 1-> declare function to calculate value of ...
Read MoreC++ Program to compute division upto n decimal places
Given with the value of x and y as a positive integer with the value of n for number of decimal places and the task is to generate the division up to n decimal places.ExampleInput-: x = 36, y = 7, n = 5 Output-: 5.14285 Input-: x = 22, y = 7, n = 10 Output-: 3.1428571428Approach used in the below program is as follows −Input the value of a, b and nCheck if b is 0 than division will go upto infinite and if a is 0 than result will be 0 as something divides to 0 is ...
Read MoreC++ Program to check whether points in a 3-D plane are Coplanar
Given with the points (x1, y1, z1), (x2, y2, z2), (x3, y3, z3) and (x4, y4, z4) and the program must check whether the given points are coplanar or not. Points are said to be coplanar is they lie under same plane and if they are under different-2 planes than the points are not coplanar.Given below is an image containing four points and all are under same plane which is xy plane that means points are coplanarGiven below is an image containing four points and all are under different planes which shows points are not coplanarExampleInput-: x1 = 2, y1 ...
Read MoreC++ Program to check if a given number is Lucky (all digits are different)
Given with a number and the task is to check whether the input number is a lucky number or not and display the result.What is a Lucky NumberLucky number is the number whose each and every digit is different and if at least one digit is repeating than the number will not be considered as a lucky number.ExampleInput-: n = 1234 Output-: it is a lucky number Explanation-: As there is no repeating digit in a number n so it is a lucky number Input-: n = 3434 Output-: it is not a lucky number Explanation-: In the given number ...
Read MoreC++ Program to calculate the number of odd days in given number of years
Given with the positive integer value n and the task is to generate the number of odd days till the given year n.ExampleInput-: days = 500 Output-: number of odd days are: 5 Input-: days = 400 Output-: number of odd days are: 0How to calculate the number of odd days in given number of yearsFor calculating the number of odd days the first thing we need to check is whether the given year is a leap year or not because if it’s a leap year than the number of odd days will get changed. If the year is divisible ...
Read MoreC++ Program to calculate Double Integration
We are given with the lower limit of variable x, upper limit of variable x, lower limit of variable y, upper limit of variable y, steps taken for corresponding x and steps taken for corresponding y and the task is to generate the double integration and display the result.ExampleInput-: steps for x = 1.2 steps for y = 0.54 lower limit of x = 1.3 upper limit of x = 2.1 lower limit of y = 1.0 upper limit for y = 2.1 Output-: double integration is : 2.1Approach used in the below program is as follows −Input the value ...
