Here you will be introduced to the comments in C and some basic arithmetic operations on variables and you will learn various shorthand operators. Let's get started- Comments in C : Comments in C/C++ and in any other programming languages serve the purpose of improvement of readability of the code. Comments are enclosed within /*-----------*/. This symbol is used for multiline comments. For single line comments we use // symbol ( two backslashes) The rules of programming language aren't applicable within comments. The text doesn't appear in the output of the code but it appears in the source code. It just makes the program readable for the coder. This is a C code to illustrate comments. Add caption Output. Nesting of comments : Comments written with /*----/*---*/--------*/ can't be nested and are invalid but a comment with /*------//------*/ can be nested. The f...
