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++?
<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:
cout << "Hello, world!";
Brackets denote blocks, which provide scope for variables. They are used in loops and conditionals:
// 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.
Cheers.
Thank you, MyndFyre.
