Question

I want to Print a Pyramid of stars (char) using nested loops.. help me out with the algorithm

Answer 1

which language

Answer 2

using wich langauge [c++ or c#]

Answer 3

Where total is the total amount of stars you want to use

for(int i = 0; i <= total; i++)
{
for(int j = 0; j <= total; j++)
{
print *
}
newline
}

this is the logic for a right angled triangle, it should be enough to help you solve the pyramid. Remember you'll need to use * and {SPACE}

Answer 4

int total = 9; //Am suposing its and odd number

for(int left = total/2, int right = left + 1; left >=0 ; left--, right++ )
{
int i = 0;

for(; i < left; i++)
cout << " ";

for(i = left ; i < right; i++)
cout << "*";

for(i = right; i < total; i++)
cout << " ";

cout << endl;

}

this should print:
*
***
*****
*******
*********

Theres an idea, prob it have some mistakes, hope it help u.

Answer 5

In Python:

>>> def pyramid(n):
... for i in range(n):
... print(' '*(n-(i+1))+'*'*(2*i+1))
...
>>> pyramid(3)
*
***
*****
>>> pyramid(6)
*
***
*****

Answer 6

Read n
for i from 1 to n do:
for j from 1 to n - i
Write ' '
for j from 1 to 2*i-1
Write '*'
Write '/n'
