What are loops? Loops are techniques used in programming to repeat a piece of code for a certain amount of time or specific number of repetitions. They are very efficient in minimizing the work load that of repetitive nature. Most common types of loops in C# are for, while, and foreach (for each) loops. Let us see the while loop in action. We would like out program to Receive integer input from user on how many times to type a star "*". Type starts with same count as user input. Let us do it as follows (code in text at the bottom) Let us now analyze how the code works The code receive the user input as a string and convert it into integer. The while loop will continue to run as long as its condition(s) are met or true. As long as the condition (num>0) is true, it will type a star "*". The num-- is self decrement of the integer num by 1. That is, it will decrease from its value each time the loop is executed. When num becomes zero, the whil...
In this lesson, we will learn What are row and column vectors and how to use them. Perform simple plotting of variables in the x-y plane. What the following video No go and test the above in your Matlab!
In this lesson, we would like that The console window prompt the user to type their name. The program capture their input as a string/text. The program reply backs with the greeting. Here we go! Code the following (code in copy-able text is available below) Press F5 to build and run... Type you name as prompted, press Enter.. Let us now analyze the code We have used Console.ReadLine() to read input from user. We stored user input in a variable of string type. String variable are used to store and manipulate plain text. String concatenation is done by the plus "+" operator as shown in the example. Here is the code in copy-able text ----- using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace MyApp1 { class Program { static void Main(string[] args) { ...
