In a for loop, the iterator variable is used for keeping track of what?
how many for loops are running in a program

How many times the for loops has iterated.

When declaring a for loop, you can declare the iterator variable, choose a condition in which the for lool exits, and choose how the iterator variable changes after each iteration.

for (int i = 1; i <= 10; i++)
std::cout << i << "\n";
