Parts of a Loop

Question

for(condition) {
body
}
So my question is what is the proper term for the (condition). I know that inside the condition you may include the three arguments, but is there a proper term for what those arguments are inside of?

Answer 1

for(initial variable(s); test expression; update expression)
{
//body
}
Example of initial variable - int a = 2, or a (Some previously declared a).
Example of test expression - a<77, or a!=6.
Example of update expression - a++, or a-=3.
Simple example:
for(int i=0;i<10;i++)
{
//Do something 10 times!
}
The update expression can be anything in general, not just increment or decrement.
A weird example:
for(int i=0;i!=5;cin>>i)
{
//Run the loop till i reads 5.
}

Answer 2

@Lithia
Sorry, I misunderstood your question.
After all, that is what the first thing that comes to mind when you see 'Parts of a loop'.
The parenthesis have no such special name. They can be called 'the function call operator',but I prefer to simply call them function parenthesis.

Answer 3

for(initialization;condition;increment/decrement)
{
}

Answer 4

I wasn't asking for what the arguments are called or what they do, but thank you for your answers. I was trying to ask what the () is called, and I've found that it is called the function call operator. Thank you @Kinshuk for your last example, I didn't know you could do that.
