For volume and surface area of a sphere, firstly declare a variable with the value of radius.int r = 15;Get the volume f the sphere.// calculating volume of sphere cal_volume = (4.0 / 3) * (22 / 7) * r * r * r;Now the surface area of the sphere ... Read More

The following is our integer array −int[] myArr = new int[6] {    8,    4,    2,    5,    9,    14 };Firstly, get the length of the array, and loop through the array to find the sum of the elements. After that, divide it with the length.int ... Read More

To find the product of two binary numbers, firstly set them.val1 = 11100; val2 = 10001; Console.WriteLine("Binary one: "+val1); Console.WriteLine("Binary two: "+val2);Now loop through to get the product.while (val2 != 0) {    digit = val2 % 10;    if (digit == 1) {       val1 = ... Read More

Using Synchronization, you can synchronize access to resources in multithreaded applications.A mutex can be used to synchronize threads across processes Use it to prevent the simultaneous execution of a block of code by more than one thread at a time.C# lock statement is used to ensure that a block of ...
