Read MorePrinting Multi-Dimensional arrays in Java
A multi-dimensional array can be easily printed using java.util.Arrays.deepToString() in Java. This method converts the multi-dimensional array to string and prints the array contents enclosed in square brackets. What Are Multi-Dimensional Arrays? Multi-dimensional arrays allow you to store data in a matrix-like structure, providing a way to represent tables, grids, or more complex hierarchical data. The most common type is a two-dimensional array, but Java supports arrays with more than two dimensions. int[][] array = new int[rows][columns]; Using Naive Approach The Arrays.deepToString(arr) method from the Arrays class ...

Complex numbers are numbers that are expressed as a+bi, where i is an imaginary number and a and b, are real numbers. Some examples of complex numbers are − 2+3i 5+9i 4+2i Example A program to perform complex number multiplication is as follows − #include using namespace std; int main(){ int x1, y1, x2, y2, x3, y3; cout y1; cout y2; x3 = x1 * x2 - y1 * y2; y3 = x1 * y2 + y1 * x2; cout
Read MoreNested Classes in C++
A nested class is a class that is declared in another class. The nested class is also a member variable of the enclosing class and has the same access rights as the other members. However, the member functions of the enclosing class have no special access to the members of a nested class.
