Answer 3

Which language are you using?
In C# you can do it like this:

for(initialization; expression;)
{
statements;
increment; (optional)
}

Answer 4

Depends on the language. In most languages you can skip some parts of the for loop, for example: for(int i=0;i<10;)
Here you skip the increment part, also you can skip initialization for(;i<0;i++)
