Stuck trying to copy a variable eg. var1 = var2; After a call like this I think that var1 is changed anytime var2 is. I think I need to use pointers but when I tried this, I got the same problem.

if you have something like below, it should work for you.
int main()
{
int num1 = 3;
int num2 = 5;
num1 = num2; // num1 == 5 && num2 == 5
return 0;
}
the other thing is, what kind of variables are they? Are they ints? floats? depending on what type of variable you have can affect how you should be assigning the value of one to the other...
Hope this helps

Thanks for the help, sorted it now. My problem wasn't what I thought, I had some values as int copying from float. This was giving weird results.

int var1=2;
float var2=5.;
var1=(int)var2;//this is all ok
float var2=5.;
var1=(int)var2;//this is all ok
