Somebody told me that if(myvariable==true) was not the same as if(true==myvariable) is that right ? if yes, what is the difference thanks

well, they arent the same in appearance, but other than that they are the same.

using if(true==myvariable)
you can prevent the tipical error "if(myvariable=true)" because true is a constant and you can''t assign values to constants...

I would prefer this:

if(myvariable)
{
}

Also, prevents you on the mistake mentioned above!

A lot of code checking programs (PC-lint) don''t like "if"s with no explicit comparison.

the difference is the order that they are evaluated in, when only looking at variables they are the same however if they are functions then there can be a difference:

  bool myFunc(int a){        cout << a;        return true;}if(myFunc(5)==myFunc(3))if(myFunc(3)==myFunc(5))  

both if statements are true but will produce different results, the first will print 53 the second will print 35

It also prevents someone who is reading your code from knowing if you are comparing a boolean to true, a pointer to NULL, or an integer to 0.
For clarity, I always write the entire explicit test.
