Triangles

[Angel1]

hi guys , just wondering if you can help in printing out a right triangle , but with words. Also using the .length in the equation . Please show me using c++

Sorry, I'm a little confused by what you're asking. Do you have anything you've already tried that I could see?

OP: also do a quick search on 'triangle(s)' through the search-box above, if you haven't done so already. this is quite a popular topic and pops up regularly

So this is the triangle printed with stars :
{
For (int bottom = 1; bottom <= width ; bottom ++)
{
For (int count = 1 ; count <= bottom ; count++ )
{
Cout<< '*' ;
}
cout<< ends;
}

}

Just wondering if you can show me how to print a right triangle with string.length in which setting it up.
I tried using the c++ search engine , but no similar topics appeared. Printing triangle with any word .

#include <iostream>
#include <string>

int main()
{
    std::string myString = "ComeOnArsenal!";
    for (size_t i = 0; i < myString.size(); ++i)
    {
        std::cout.write(&myString[0], myString.size()-i);
        //http://en.cppreference.com/w/cpp/io/basic_ostream/write
        std::cout << "\n";
    }
}

edit: strings with spaces within them will appear as if the same substring has been printed twice, it's actually two different substrings, one with the space at the back and one without. if this is of interest have a go how you might skirt this issue

thank you @gunnerfunner. i got the idea of the string but i printed the triangle by the incorrect order. can you help me fix it or anyone. please help.

my work:

cout << " Please insert a word " << endl;
cin >> word;
int length = word.length();

cout << " Is the triangle 1) up or 2) down " << endl;
cout << " 1 or 2"<<endl;
cin >> choice;

if (choice == 1)
{ // up triangle
for(int i = 0; i <= word.length(); i++)
{
for (int a = 0; a < i; a++)
{
cout << word[a];
}
cout << endl;
}


}
else if (choice == 2)
{ // down triangle
for (int i = length; i >= 0; i--)
{
for (int a = 0; a < i; a++)
{
cout << word[a];
}
cout << endl;
}
}
