Answer 1

Ther are many solutions, especially in C++.
The easiest way to do this template, just add to your code a cout Syntax:

#include <iostream>

int main() {
std::cout<<" *\n";
std::cout<<" **\n";

//Follow this shape ;)
return 0;
}

But if you want to make it "automatically", you could also make some Arrays, Loops ... ( and so also arise algorithms ).

An easy for-loop example:

#include <iostream>
using namespace std;

int main()
{

int SetAmount, Space, SomeSymbol;

//Loop SetAmount 10 times = 10 rows
for(SetAmount = 0; SetAmount <= 10; SetAmount++){

for(Space = 0; Space <= SetAmount; Space++)
cout << " ";
for(SomeSymbol = 10; SomeSymbol > SetAmount; SomeSymbol--)
cout << "*" << endl;
} return 0;
}

That example above is one of many variations. :)
