help! I cant even get this simple program..

how would you do a program that gave this output.. okay so im really new to all this......
the code is supposed to have 2 nested for loops.....

this is what i have, but as you can see does not workint main()
{

for (char stars = 0; stars < 10; stars++)
cout << '*'<< endl;
{
for (char stars = 0; stars < ; stars -= 1)
cout << '*';
}


return 0;
}

Using two nested loops is an innefective way of doing this but as you apparently need it for homework you probably *have* to have it done this way... Okay them:

Code:

---

for(short rows = 0; rows < 10; rows ++)
{

  for(short length = 0; length < rows; length ++)
  {
      printf("*");
  }

  printf("\n");
}

---

That looks like it would work.... Use cout if you'd like but i prefer printf.

Since he wants the longest string first, I think it should be:

Code:

---

for(short rows = 0; rows < 10; rows ++)
{

  for(short length = 0; length < 10-rows; length ++)
  {
      printf("*");
  }

  printf("\n");
}

As an exercise, you may want to look again at this line and spot the errors...

for (char stars = 0; stars < ; stars -= 1)

... finding those will help you understand for loops and a few other things.

Well, first of all you don't have a condition how long the loop will last (stars < ).

Secondly, I believe char is automatically unsigned when not specifically signed/unsigned so stars -= 1 will screw up the calculation (will probably give it the value 255 instead of -1).

That's all, I believe... except that there is no code that is looped :)

Errr, I meant he should, (the original poster), look at his program...
