passing variable to 'for' loop

[moonshadow9988]

can you only pass pointers, or is it the way im declaring the variable is incorrect?

I don't understand what you are asking. Can you explain some more or post some code?

float a;
float *p_a = &a;

for (int b = 0; b < 5;b++){
*p_a = b;
}


ok this is all nested in a function that is a member of a class, the variable is declared within the function, and when trying to use it in a for loop (also in the same function), it gave me an error. So, I had to use a pointer.

I was wondering, whether this had to do with the function being a member of a class or do you always need pointers when dealing with for loops.

Do you know what the error was?

There should be no problem with code such as

class Foo
{
    void Bar()
    {
        float x;
        for(int i =0; i< 5; i++)
        {
            x = i; // Warning C4244: '=' : conversion from 'int' to 'float', 
                     // possible loss of data

       }
    }
};
