Help with tutorial on C++

Ok so i'm trying to now figure our while, for, do.
Its not explaning one thing:
Can while be done "while" for is happening?
How can you use all 3 in 1 code.
Heres what i tried to write:

Code:

---

#include <iostream>

using namespace std;

int main()
{
  int x=1;

 
  for (int x =1;x>=0||x<=10; x=x+2)
  { cout<<x<<endl;
}
cin.get();
while (x==9) {cout<<x-9; }
  do {
    cout<<"Learning to count!\n";
  } while ( x !=0 || x !=1 ||x !=2 );
  cin.get();
}

---

Anyone, i can't understand.

Your example is such an example, but the problem is that all your loops are infinite loops (once they start running, they never terminate), so actually running your code could pose a problem.

Incidentally, you should format your code to make it more readable, e.g.,

Code:

---

#include <iostream>

using namespace std;

int main()
{
    int x = 1;

    for (int x = 1; x >= 0 || x <= 10; x = x + 2)
    {
        cout << x << endl;
    }

    cin.get();

    while (x == 9)
    {
        cout << x - 9;
    }

    do
    {
        cout << "Learning to count!\n";
    } while (x != 0 || x != 1 || x != 2);

    cin.get();
}

---

Incidentally, I note that you have two variables named x in main(). One is in the for loop.

If i understand your question correctly, you want to enter a while loop inside a for loop, this is known as nested loops, and the answer is yes, it can be done :)

Code:

---

for(unsigned int i = 0; i < 10; i++)
{
    unsigned int j = 0;
    while(j < 10)
    {
          j++;
    }
}

---

This means, that each time the for loop, loops 1 time, the while loop is looped 10 times (from 0 to 9).

Is this what you meant?

Yes You Are A Genius!!!!!!!!!!!!!

you can also do a nested for loop inside with j.
