C++ Program to Print Number Entered by User

In this example, you'll learn to print the number entered by a user using C++ cout statement.

Example: Print Number Entered by User

#include <iostream>
using namespace std;

int main()
{    
    int number;

    cout << "Enter an integer: ";
    cin >> number;

    cout << "You entered " << number;    
    return 0;
}
Output
Enter an integer: 23
You entered 23
This program asks user to enter a number.
When user enters an integer, it is stored in variable number using cin.
Then it is displayed in the screen using cout. Read More C++

Creating a Cursor from a Font Symbol in a WPF Application

Image
Introduction I had to create a large cursor for the application I was working on and, since I was already using a symbol font, decided to use a symbol from the font for the cursor. NOTE The code has been considerably updated to fix issues with the cursor since the initial version. The image in the cursor was not properly centered so that the actual size of the cursor was not close to the value that is specified in the call. The hourglass also now has a three images of the sand going down and then a 90 degree rotation.  The Code I started out trying to use code that I used to generate images from fonts for buttons and such, which is included in the code, and what is used to generate the image in the Sample. That did not work, and I had to search the internet and play around with it a lot. Unfortunately, there seem to be several Microsoft libraries for drawing, and I guess not a lot of thought was put into creating the different ones. The code below is what eventually worked.

C++ Program to Find All Roots of a Quadratic Equation

This program accepts coefficients of a quadratic equation from the user and displays the roots (both real and complex roots depending upon the determinant). To understand this example, you should have the knowledge of following C++ programming topics: C++ if, if...else and Nested if...else For a quadratic equation  ax 2 +bx+c = 0  (where a, b and c are coefficients), it's roots is given by following the formula. The term  b 2 -4ac  is known as the determinant of a quadratic equation. The determinant tells the nature of the roots. Read More  C++ If determinant is greater than 0, the roots are real and different. If determinant is equal to 0, the roots are real and equal. If determinant is less than 0, the roots are complex and different. Example: Roots of a Quadratic Equation #include <iostream> #include <cmath> using namespace std ; int main () { float a , b , c , x1 , x2 , determinant , realPart , imaginaryPa

C++ Program to Find Quotient and Remainder

In this example, you will learn to find the quotient and remainder of a given dividend and divisor. In this program, user is asked to enter two integers (divisor and dividend) and computes the quotient and remainder. Read More  C++ To compute quotient and remainder, both divisor and dividend should be integers. Example: Compute quotient and remainder #include <iostream> using namespace std ; int main () { int divisor , dividend , quotient , remainder ; cout << "Enter dividend: " ; cin >> dividend ; cout << "Enter divisor: " ; cin >> divisor ; quotient = dividend / divisor ; remainder = dividend % divisor ; cout << "Quotient = " << quotient << endl ; cout << "Remainder = " << remainder ; return 0 ; } Output Enter dividend: 13 Enter divisor: 4 Quotient = 3 Remainde
