Same here. It has some java and javascript like syntax, but I don't really understand pointers and casting and stuff…

int* var1 = new int;

int* var2 = new int[666];

delete var1; delete var2[]

double var1 = 6.66; int var2 = (int)var1;

CMyEnt* myent = gEntList.FindEntityByClassname( "my_ent", NULL );

CMyEnt* myent = (CMyEnt *)gEntList.FindEntityByClassname( "my_ent", NULL );

They're pretty simple.

Pointers don't contain data themselves, but reference addresses in memory, and are created with the “new” syntax and freed with the “delete” syntax. So to create a pointer in C++, you would do

int* var1 = new int;

for an individual variable (integer for this case), and

int* var2 = new int[666];

for an array of integers containing 666 elements, and at the end you would do

delete var1; delete var2[]

to free up memory they used. They are much more dynamic than static variables.

As for casting (explicit type conversion), it's basically converting variable types - it can be useful for trimming decimals off double variables by converting it into an integer, which would work as so:

double var1 = 6.66; int var2 = (int)var1;

(which could be done implicitly, but I used this to demonstrate).

You could also do this with classes. So say, for instance, you were modding the Source engine and needed to have your entity, class name CMyEnt, to be searched. You can't do

CMyEnt* myent = gEntList.FindEntityByClassname( "my_ent", NULL );

because the aforementioned function returns a type of CBaseEntity*, not CMyEnt*. But what you could do is convert the result of the function to a type of CMyEnt*, because CMyEnt inherits from CBaseEntity:

CMyEnt* myent = (CMyEnt *)gEntList.FindEntityByClassname( "my_ent", NULL );

Sorry if I'm bugging you with all this information, but I felt the need to help.

reinterpret_cast
const_cast
static_cast
dynamic_cast

void sample(Text t){
    noscope(t);
}

void Sample( Text t )
{
    Noscope( t );
}

Cool, thanks.

When I said casting, I meant that I didn't understand these

reinterpret_cast
const_cast
static_cast
dynamic_cast

I understand Java casting, which is basically what you explained. But what are these for?

Also, I feel like if I go into C++, I'll never get used to the style

void sample(Text t){
    noscope(t);
}

is so much neater than

void Sample( Text t )
{
    Noscope( t );
}

And I also feel like I'm going to leave objects in memory all over the place without garbage collection…

I always need to check to see if I am supposed to use “<<” or “>>” for “cin” or “cout.”

I make many mistakes.

“>>” is an insertion operator, so you use it with “cin” to get the user's input, and vice-versa for “cout”. Think of it in the sense that the arrows go from a data collector and point toward data storage.
