What's wrong with my for loop?

Question

I am making a game using lite-C (exactly same syntax as C). and I cannot make this loop work. It gives me an error at this line at compilation.
for(int i = 0; i < (cantenemigu * 3); i += 3)

I have an array with the information of where to create the enemies. the array contains the x,y,z coordinates.
cantenemigu is the amount of enemies that there are in the array.

With this loop I would get the information of each enemy and create it.

[EDIT] The answers didn't work. I added the ; acsidently while writing the post.

Maybe the problem is somewhere else;

Here is the hole part.

int cantenemigu = 3;
var posenemigu[] = {-900, 550, -10, -1100, 1600, -10, 70, 1680, 20};
void load_enemigunan()
{ 
 for(int i = 0; i < (cantenemigu * 3); i += 3) 
 {
  ent_create("targetr.mdl",vector(posenemigu[i],
             posenemigu[i + 1],
             posenemigu[i + 2]),NULL);
 } 
}

This is the code if I don't add the <br>

I solved it.

this worked.

int i
for(i = 0; i < 3*cantenemigu; i += 3)
{
    ent_create("targetr.mdl",vector(posenemigu[i],
                                                posenemigu[i + 1],
                                                posenemigu[i + 2]),NULL);
}

In C# it doesn't have be declared before. I assumed it was also so in C. (or maybe it's a bug in the compiler).

Answer 1

for (int i = 0; i < (cantenemigu * 3); i += 3)

There should not be any ; after i += 3.

Answer 2

Get rid of the 3rd ;.

for(int i = 0; i < (cantenemigu * 3); i += 3) 

Answer 3

for(int i = 0; i < (cantenemigu * 3); i += 3;) 

What is the error? That last semicolon shouldn't be there.

What is the body of the loop?

What type of variable is cantenemigu? Can it be coerced to int?

Answer 4

It looks like you are missing a closing parenthesis for your call to vector.

ent_create(
    "targetr.mdl",
    vector(
        posenemigu[i], 
        posenemigu[i + 1], 
        posenemigu[i + 2],
        NULL
);

Answer 5

Try changing your code to this: (note what I've done is move the declaration of i outside the for loop.

int cantenemigu = 3;
var posenemigu[] = {-900, 550, -10, -1100, 1600, -10, 70, 1680, 20};
void load_enemigunan(){ 
    int i;
    for(i = 0; i < (cantenemigu * 3); i += 3){
         ent_create("targetr.mdl",vector(posenemigu[i],
             posenemigu[i + 1],
             posenemigu[i + 2]),NULL);
     } 
}
