Newbie here! Why i get a result on for loops?

[Eren Jager]

After debugging it I get this result.
I just started learning using for loops today and it confused me.

number 1
number 4
number 9
number 16
number 25
number 36
number 49
number 64
number 81
number 100

  #include <iostream>

using namespace std;

int main()
{
	int a;

	for (a = 1; a <= 10; a++)
	{
		cout << "number "<< a * a << endl;
	}
	
}

[Stauricus]

a = 1 (1*1 = 1)
a = 2 (2*2 = 4)
a = 3 (3*3 = 9)
[...]

well, so what's the question?

Could you clarify, is there a specific question that you have?

See the tutorial for explanation of loops:
