Day 5!........... For Loops!

What in the world are For Loops?

Definition: For Loops are disigned to iterate a number of times.
Basically a template for a for loop looks like this...
for(initialization; condition; increase/decrease) statement; bla bla bla

So this would be a cool for loop for a SpaceX countdown.
Don't copy the code, try to write it yourself.

#include <iostream>
using namespace std;

int main()
	for (int n = 10; n>0; n--) {
		cout << n << ", ";

	cout << "Liftoff!\n";


Initialization: Is executed, and sets it to some inital value.
Condition: This is checked, and if true, run, if false, end.
Statement: basically the statements enclosed in the curly brackets.
Increase: is executed and loops over again until false.

While Loops!

What are While Loops?

In a while loop, the condition is evauated first and if true, then the statement in sde the while loop will be executed. This will continue until the condition becomes false. When the condition is false, it comes out of the loop and goes to the next statement.
Syntax of a while loop:



A Example:

#include <iostream>
using namespace std;
int main()
	int i = 1;

	while(i <= 6){
		cout << "Value of variable i is: " << i << endl; i++;

This will print out the numbers 1,2,3,4,5,6.

Ummmm that's it!

Build a launch sequence again,
but instead of it launching, make it abort.
Like this: 10,9,8,7,6,5,4,3, abort!
Using a while loop, make a infinite sequence.
Go study pointers, because the next one is going to be HARD

Hey everyone, all these competitors in the tutorials section must be wiped out.

Everyone upvote! (To dominate the tutorial section.)
