#include <iostream> // This line of code is necessary to include all the C++ standard functions\classes definitions

usingnamespace std; // Set our namespace to standard (don't stress on this right now)

void main() // This creates our function main()

{ // Beginning of the program

int min=0, max=0, i=0; // We initialize 3 integer (number) variables to store

// Our range. We set them equal to zero or else they

// Will be some crazy number like -858993460. We could

// Also have said:

// int min=0;

// int max=0;

// int i=0;

// They are the same thing, it is just cleaner the other way

// Now we prompt the user to input a number for the min

cout << "Input your first number to count from: ";

// Then we wait until they press <enter> and read what they typed in

cin >> min; // We store the number they type in in the variable "min"

// Now we prompt the user to input a number for the max

cout << "Input your last number to count to: ";

// Then read in the maximum number to count to and store it in the variable "max"

cin >> max; // Now we have the maximum number they want to count to store

// Now here comes the loop:

// This is called a "For Loop". You will use these a million times.

// Ok, here is what it does. It gets a starting point

// "i=min" "i" is used as a counter

// "i" now equals min, let's say we typed in 10.

// This is the same thing as saying "i=10", but we don't

// Know WHAT the number is so we hold it in a variable: min

// "i <= max" This says, keep looping until this condition is false. 

// In this case, "Keep looping until i is greater than max."

// Let's pretend that max is 15. The loop will quit when i = 16 or over

// You might be thinking, why would i = 16 or over? "i" equals "min" (let's say 10)

// Well, the next parameter passed into the "for" loop is where we say what happens to "i"

// "i++" This tells the compiler to add 1 to "i" each time through

// This is the same thing as saying : "i = i + 1", It's just shorthand

// for(start, condition for the loop, after we go through the loop each time - do this) )

// You'll also notice we don't have a ";" after the "for" loop...

// Good "i"! :) if we put a semicolon after this, the loop would never run.

for(i=min; i <= max; i++) // That is because a ";" says we are done with the line, we ARENT... We never put a ";" after anything with a "{" after it .. look at "void main()" ..

{ // We have a "{" to say everything after "{" is in the loop

cout << i << endl; // Here we print out i each time through the loop and go to the next line 

} // Everything after "}" is out of the loop, if the loop is not finished, go back to the top

// You might be wondering what this does? If so.. let's go through the loop:

// Let's stick to our previous example of min=10 and max=15

// for(i=10, 10 <= 16, 10 + 1 (only if middle condition is not met, so i still = 10) )

// {

// cout << i << endl;

// }

// That is one time through the loop, when it hits "}" .. The loop executes the 3rd parameter:

// Which happens to be "i++". Now, i = 11 right? we just added 1 to i which was 10.

// The compiler never goes back to the first parameter which was "i=min". That was just to start "i" off.

// So, after the first loop, and we add 1 to "i", the compiler goes and check the middle condition

// To see if the loop should continue.. So:

// "11 <= 16" It's still TRUE, so we go through the loop again.

// Now we print out 11, then 12 <=16, then print 12, etc...

// Until we print out "16" , after the loop ends, 16 gets 1 added to it. i = 17

// "17 <= 16" This is FALSE, so the loop quits and the code 

// Goes past the loop and past the "}". Since there is nothing else in the program, the program is over.

} // We end "main()" ending our program

// We just completed our first for loop. Pretending we typed in 10 and 15, here is the output:

// Input your first number to count from: <we type in 10 and press ENTER>

// Input your last number to count to: <we type in 15 and press ENTER>

// 10

// 11

// 12

// 13

// 14

// 15

// Press any key to continue
