18 Tutorials. C# falls under the internationally accepted general-purpose, high-level, object-oriented programming language developed by Microsoft Corporation. This tutorial will teach complete C# and its usage from basic to various advanced programming concepts. Example explained. Expression 1 sets a variable before the loop starts (int i = 0). Expression 2 defines the condition for the loop to run (i must be less than 5). If the condition is true, the loop will start over again, if it is false, the loop will end. Expression 3 increases a value (i++) each time the code block in the loop has been executed.

Notes on Pointers. Pointers are one of the things that make C stand out from other programming languages, like Python and Java. They are important in C, because they allow us to manipulate the data in the computer's memory. This can reduce the code and improve the performance. Get Started With C. To start using C, you need two things: A text editor, like Notepad, to write C code. A compiler, like GCC, to translate the C code into a language that the computer will understand. There are many text editors and compilers to choose from. In this tutorial, we will use an IDE (see below). char firstName [30]; // Ask the user to input some text. printf ("Enter your first name: \n"); // Get and save the text. scanf ("%s", firstName); // Output the text. printf ("Hello %s", firstName); Run example ». Note: When working with strings in scanf (), you must specify the size of the string/array (we used a very high number, 30 in our ...
