Yes, but we're not a do your homework service, or a substitute for your classes or books. What have you got and where are you stuck?

Then spend a few more hours, or days or weeks. Start at the beginning of the book and read and reread till it makes sense. You need some understanding of the basics before this forum can help you.

You'll need a for loop and the cout statement.

## Re: Pyramid of stars with spaces

I need program which draw this nice pyramid with for cycle, N=number of lines...
i need only content of for cycle

So how far have you got? Post the code you've got so far (even if it doesn't compile or work) and we'll give you some pointers towards your next steps. As it's homework we can't write the code for you as that would be considered cheating. If you are having trouble learning the basics from your tutor you might want to look at these on-line tutorials for c++.

http://www.cplusplus.com/doc/tutorial/
http://www.learncpp.com/

Have you used the cout statement in previous programs you're written and got to work properly? Have you used a for loop before?

#include <iostream>
#include "funkce.h"
using std::endl;
using std::cout;

void pyramida(int N, char symbol){

for(int i=0; i<N; i++){
cout << symbol << string(i, " ") << endl;
}

}
i need to find right logical condition into for

9. ## Re: Pyramid of stars with spaces

When you post code, please could you use [code] tags. I should have mentioned this in post #7. Click Go Advanced, select code then click '#'. A couple of pointers.

Code:
`cout << symbol << string(i, " ") << endl;`
With string() you are trying to create a string of i spaces. However, this will give a compiler error as the space needs to be in single quotes for a character rather than double quotes for a string. Also cout prints from left to right. So you are first printing the symbol and then printing a number of spaces and then a new line!!

10. ## Re: Pyramid of stars with spaces

Have you actually tried to compile and run this progam? You need to have a main() function that calls your pyramida() function. As you are using the string class, you will also need to have #include <string> as well togther with using std::string; Try compiling and running this program. Look at the output and then see if you can figure out what else needs to go in the for loop to produce the triangle.

Happy coding

Yes, i have function.cpp, function.h and main.cpp but all what i need is logical condition into for cycle

Code:
```void pyramida(int N, char symbol){

cout << symbol << endl;
for(int i=0; i<N; i++){
cout << string(i, ' ') << endl;
}```

Try this for a starter hint. See what it displays and then see if you can add the code to complete it.

Code:
```void pyramida(int N, char symbol)
{
for (int i = 0; i < N; i++){
cout << string(i, ' ');
cout << symbol << endl;
}
}```
