So i have basically just been hammering away at c++ not really reading any books or tutorials.

What is the difference between a for and a while?

It's just the method of execution (as far as i know)

for (int i = 0; i < 10; i++)
{
//code
}

int i = 0;
while (i < 10)
{
//code
i++
}

same thing, different code.

Well, a while loop keeps on going until a condition is false ex:


And a For Loop keeps on going until a condition is meet (in the example, it is while variable "i" is less than "10".



You can also see that For loops can be used to cycle through arrays, while loops can do this too, but it's a bit more logical for a for loop to do that.

For loops are used when you know in advance how many times you want the loop to be executed. An example is going through a fixed-size array. The while loop is used when you don't know how many times the loop will be executed, you only know that it should keep running as long as the condition is met.
