What is wrong?

I need to fix each of these codes so that it will print numbers between 1 and 10. what is wrong?

Code:

---

#include <iostream>
using namespace std;
int main (void){
for (int n=1; n<=10; n++);
cout << n << endl;
return 0;
}

---

and

Code:

---

#include <iostream>
using namespace std;
int main (void)
{ n=1;
while (n<11)
cout << n << endl;
n++;
return 0;
}

---

any help would be appreciated, thanks

Code:

---

#include <iostream>
using namespace std;
int main ()    // void not necessary, but you can still put it there
{
 for (int n = 2 ; n<10  ; n++) // no semi colon at end of for
    cout << n << endl;

return 0;
}

Leave the other for you to do. If you meant you wanted to print between 0 and 11, then you should be able to change that easily.

Thanks for the help. Could you possibly explain why making the change is necessary? I'm new to programming, and am having some difficulty understanding what everything means.
thanks

well the symmantics of the for loop are as follows:

Code:

---

for ( int i = 0; i < 9; i++ ){
      cout << i << endl;
}

---

the int i = 0 is setting the starting value for i to zero.
the i < 9 sets the upper limit of the counter, ie do whatever is in the braces until i is less than 9,
the i++ increments the i by 1 each time the loop is run

consequently the output for i will be
0
1
2
3
and so on till
8

hope this helps...you could also look into your book, or the cprogramming.com tutorials,

well if this is the case, why are the two codes that i gave wrong?

Code:

---

#include <iostream>
using namespace std;
int main (void){
for (int n=1; n<=10; n++);
cout << n << endl;
return 0;
}

---

Code:

---

#include <iostream>
using namespace std;
int main (void)
{ n=1;
while (n<11)
cout << n << endl;
n++;
return 0;
}

---

why wouldn't these output the integers 1 through 10?

The first is wrong because you have a semi-colon on the end of the for() line.

The second is wrong becuase the n++; line is not within the loop. As you have 2 lines of code that you want to run inside the loop, you must encase them with {}.

Ok, thank you. That makes a lot more sense.
