Question of declaration

Thank you,

What is the faster for a programm?

To declare variables one by one, or in an array?

this is a bit like splitting hairs. either method works fine and the difference in speed between the two is going to be hardly noticable.

if you are having problems needing to optimize metatrader code, omg, get a faster computer, i run my metatrader on a p2 processor and my EA runs like greased butter.

/*
question: Can we declare variables in a loop, by this way for exemple?

answer: a correct syntax might look like this:


int i;

for(i=1,i<10,i++)
{
i=i+1; 

//or you could use the shorthand version of: 
i++;
//i++ is shorthand for i=i+1;

//
//your posted syntax is entirely incorrect.
//variable+"i"= value+"i";
}

But I tried my syntax and it doesn't works,I think the array is the better solution, but I want to put string variables in it.

Is this possible?

I don notr succeed.
