GoTo function like CMD?

I tried using, "system(":test2");"
and then "system("goto :test2");"
but it didn't change the way the program ran at all.

Is there anything similar to the CMD goto command that would allow you to skip around in C++ code, or would it merely be easier with functions?

Also, before you say something along the lines of "Read the fucking manual", I've looked through 2 books today and search online for about an hour with no results.

If your trying to skip around in code like that... though I don't recommend it just create a jump point by saying something like [php] int i;
test: // will jump back to this point
doSomethin();
doSomethingElse();[/php]

[php]
int i = 3;
goto: test; // will jump back to the line test and execute from there
...
doSomething3();
[/php]

At least I'm pretty sure that is how it works. Tell me if I'm wrong.
