A matrix is a rectangular array of numbers that is arranged in the form of rows and columns.An example of a matrix is as follows.A 3*3 matrix has 3 rows and 3 columns as shown below −8 6 3 7 1 9 5 1 9A program that multiplies two matrices using multidimensional arrays is as follows.Example Live Demo#include using namespace std; int main() { int product[10][10], r1=2, c1=3, r2=3, c2=3, i, j, k; int a[2][3] = { {2, 4, 1} , {2, 3, 9} }; int b[3][3] = { {1, 2, 3} , {3, 6, 1} , {2, 9, 7} }; if (c1 != r2) { cout
Use the transform CSS property to flip an image. You can try to run the following code to flip an image on mouseover:ExampleLive Demo .myimg:hover { transform: scaleX(-1); } Heading One Let's flip the image on mouse over:
Operator overloading can be done with most of the built-in operators in C++. The overloaded operators are functions with the keyword operator followed by the operator symbol that is defined. The overloaded operators have a return type and a parameter list like any function.A program that subtracts complex numbers using operator overloading is as follows −Example Live Demo#include using namespace std; class ComplexNum { private: int real, imag; public: ComplexNum(int r = 0, int i =0) { real = r; imag = i; } ComplexNum operator - (ComplexNum const ...

There are 128 characters in the ASCII (American Standard Code for Information Interchange) table with values ranging from 0 to 127.Some of the ASCII values of different characters are as follows −CharacterASCII ValueA65a97Z90z122$36&38?63A program that finds the ASCII value of a character is given as follows −Example Live Demo#include using namespace std; void printASCII(char c) { int i = c; cout
Multiplication of two numbers a and b yields their product. Value of a is added as many times as the value of b to get the product of a and b.For example.5 * 4 = 20 7 * 8 = 56 9 * 9 = 81Program to Multiply two Numbers using * OperatorA program to multiply two numbers using the * operator is given as follows −Example Live Demo#include using namespace std; int main() { int a = 6, b = 8; cout
A palindrome number remains the same if its digits are reversed i.e its value does not change. A palindrome number can also be called symmetric. For example: The numbers 12321, 1551, 11 etc are palindromes as they do not change even if their digits are reversed.A program that checks if a number is palindrome or not is as follows.Example Live Demo#include using namespace std; void palindrome(int num) { int rev=0,val; val = num; while(num > 0) { rev = rev * 10 + num % 10; num = num / 10; } if(val==rev) cout
Use the tag to create a command/ menu item that the user can invoke from a popup menu in HTML5. The HTML tag is used for defining a menu item for a menu.The following are the attributes of the tag −AttributeValueDescription checked checked defines that a menuitem should be checked default default a menuitem is marked as a default command disabled disabled disables a menuitem and cannot be clicked icon url defines an icon for a menuitem label text defines a name for a menuitem which is displayed to the user radiogroup groupname defines a group of commands out of which only one can be selectedtype ...

A quadratic equation is in the form ax2 + bx + c. The roots of the quadratic equation are given by the following formula −There are three cases −b2 < 4*a*c - The roots are not real i.e. they are complexb2 = 4*a*c - The roots are real and both roots are the same.b2 > 4*a*c - The roots are real and both roots are differentThe program to find the roots of a quadratic equation is given as follows.Example#include #include using namespace std; int main() { int a = 1, b = 2, c = 1; float discriminant, ...

Use the grid-template-columns property to define the number of columns in CSS Grid Layout.You can try to run the following code to set a number of columns. Here, 3 column grid is set:ExampleLive Demo .container { display: grid; background-color: yellow; grid-template-columns: auto auto auto; padding: 20px; grid-gap: 20px; } .container > div { background-color: blue; border: 2px solid gray; padding: 35px; font-size: 30px; text-align: center; } Game Board 1 2 3 4 5 6
