1. ## Simple loop

Hello all, i want to display an equilateral triangle.

I thought about it and tried all day but unfortunately didn't do it.
This is so for i've done.

Code:
```for(int i=0; i<5; i++)
{
for(int j=5; j>i; j--)

for(int k=0; k<i; k++)
cout<<"*";
cout<<" ";

cout<<"\n";
}```
Please let me know where i'm wrong in this loop.

2. You should give all the for loops curly brackets, even if you don't need to. It makes the code easier to read and helps reduce mistakes.

Also, I think you should be able to do it with only 2 for loops, as it is a 2d shape after all.

3. Firstly sorry to everyone, i've posted it twice. There was something wrong with my internet.

@rocketman50: Could you help me out please, I tried it so many times.
I'm using three loops becuz i want to make spaces from left too.

4. Ah I see, you want spaces from the left.

You are very almost there. An easy way to modify your code is to do the following.

First, sort out the brackets

Code:
```	for(int i=0; i<5; i++){
for(int j=5; j>i; j--){
cout << " ";
}

for(int k=0; k<i; k++){
cout<<"*";
}
cout<<"\n";
}```
Then you need to worry about the spacing in-between the stars. A simple IF statement would do. - i.e. if it is the not the first star on the line, add a space before printing a star. So when K is not 0, print out a space before a star.

5. I want to get an equilateral triangle , how to do this??

6. I find it helps to write a series of comments describing what the function will do, then fill in the code.

Code:
```//start at 1 and loop until equal to the number of lines in the triangle

//determine the number of spaces required
spaces = triangle - line
//determine the number of *
asterisks = ( line * 2 ) - 1

//create the string to write
//for each space
//add a ' ' char to the string
//for each astarisk
//add an '*' to the string

//display the string
//end```
Of course this will not work unless you use a fixed pitch font...
