mine is showing like this

Your second for loop's conditional part should be iColumn <= iSize - iRow .

Edited 5 Years Ago by minitech: n/a

Line32 should be for (int iRow = iSize; iRow > 0; iRow--) { Line 34 should be for (int iColumn = 0; iColumn < iRow; iColumn++) {

how come if press 1 or 11 for iSize

its showing:
The size is out of range.
"T"

Instead of setting bError = true; , just take out bError entirely and use continue; instead where bError = true; used to be. Replace the while(bError) with while(true) .

i have another question.
just to make sure
am i using double for loop???

No, why would you draw a triangle with base 5.2? You can't draw part of a T. int fits everything between 2 and 10 (and much more) so it's all you need.

im just following what is the instruction said...
can u tell me how to use double for loop?

Edited 5 Years Ago by JudeV: n/a

Yes, you're using 2 for loops, if that's what the instructions mean.
