Actually; you make a perfect combination.

I can't comprehend how you can comment on your teacher's incompetence without being familiar with the stuff yourself.

Seriously, nobody is going to do your homework for you. Read the Rules first.

Please, tell me how we make a perfect combination?
And what do you mean? I cant say my teacher is incompetent? I have gone to the guy many times, given up many lunches, and still he has not helped me understand what we are doing, he once told my class "No sane teacher would have you do this with as little skills as I have given you."
AND i have read the rules, I was not asking for anyone to do. Just asking for tips on how to get started with it. Sorry if I said it wrong. And sorry if I am percieved as rude or as an idiot in any way.

He cannot teach and I am not good at this

Two facts that are undoubtedly related

Write a password program. The user enters a String, and cannot continue with the program until they correctly get the password

Do you really not know how to do this?

This is beyond simple... get string from keyboard, compare string to password, exit if they don't match...

I am not trying to be lazy, if I was I would not have spent the last 30 minutes looking over the web for tutorials ---- And I know it isnt rocket science to you but i SUCK at dev c++ so it feels like it to me D:

Okay and thanks.

And will do.

ok, so you already know the steps that the program must accomplish:

1. ask the user for input
2. if input is equal to the password, continue. else return to step 1

now you just need to translate those steps into C++ code.

the tutorials on this site should help you with that.

Thanks Elysia. I do not quite understand why I find it confusing. My teacher only showed us one example during class and it did not have to do with string. And i havent been looking for examples of what i was assigned, I was looking for tutorials to learn how to do loops. And all of them were int.

This is the one he showed us:

Code:

#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
//x++, x+=, x-=
        int x=0, grade=0, total=0;
               while (x <= 30)    
        {
               cout<<x<<endl;
               x+=3;
       }
       /*while (true)
       {
                   if(x % 3 ==0)
                        cout<<x<<endl;
       x++;
       }*/
       
    system("PAUSE");
    return EXIT_SUCCESS;
}

Do you understand this part?

Code:

while (x <= 30)
{
               cout<<x<<endl;
               x+=3;
       }

Code:

while (x<=30) // saying while x is less then or equal to 30
{
cout<<x<<endl; // if x is equal to or less than 30
x+=3; // x= x+1

But i think my answer is wrong because it lists the multiplies of 3....

And just for reference, I reported that post.

Sometimes the best lessons are the least comfortable ones.
Programming is not an area of expertise where one can "loaf along" and be good at it, it requires a certain analytical mindset... and you don't get that from Google.

Offending post removed.

Yes, you're indeed somewhat wrong.
while(x<=30) says that the following block will keep executing repeatedly until that condition becomes false.
and x+=3 //==> x = x + 3
