ColT | Hi, I am currently learning Visual C++. I just wanted to know what <iostream> mean's. Also, I might ask some really noob question's, but please pardon me. (Edit) also what do all the }, { mean when writing code in Visual C++? | November 28, 2004, 12:57 AM |
Myndfyr | <iostream> It is a collection of functions and objects that provide for input and output. In learning C++, the most common reason to include <iostream> in console applications is the cin and cout objects: [code] cout << "Hello, world!"; [/code] Brackets denote blocks, which provide scope for variables. They are used in loops and conditionals: [code] // This if statement only executes one statement after it, if the condition returns true. if (TRUE) return; // This one executes a block of statements int i = 0; if (TRUE) { i++; i--; } // In this case, you can still access the i variable after the block exits. if (TRUE) { int i = 0; i++; i--; } // In this case, the i variable is only usable inside of the block. [/code] Cheers. | November 28, 2004, 9:01 AM |
