While I am kidding around here, I think several members of this forum told you before that we don't give out homework solutions here. It's for your own benefit, believe it or not. :)

What have you tried to get this work so far? We will happily help you after you show at least one reasonable attempt. :/

#include<iostream.h>
#include<conio.h>

main()
{
clrscr();
int n=5;

for (int i=1;i<=n;i++)
{
for (int j=1;j<=n;j++)
{
cout << " ";
}
for (int x=1;x<=i;x++)
{
cout << "*";
cout << " ";
}
cout <<"\n";
n=n-1;
}
getch();
}



it's shows no space in middle
plz give me logic

[Albatross]

Alright.

With the exception of the first and last rows, every single row has only two stars: at the beginning of a line, and at the end.

So, what I think you'll want to do is have a for loop to deal with each line (which you have), and inside that, first print one asterisk. Then, in another for loop inside your other for loop, print a number of spaces (from my little picture, do you see how the number of spaces increases?), and outside of that loop print another asterisk and a newline.

Can you try to write that?

P.S: <iostream> should have no .h, main should have an int before it, and you should return 0; at the end of int main().

[honey24]

can you correct it with showing method

[honey24]

progarm run but there is no spaces in middle

Use continue.

compile this:

#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
    cout <<" "<<endl;
    cout <<" "<<endl;
    cout <<" "<<endl;
    cout <<" "<<endl;
    cout <<" "<<endl;
    cout <<" "<<endl;
    cout <<" "<<endl;
    cout <<" "<<endl;
    cout <<"                     *"<<endl;
    cout <<"                     * *"<<endl;
    cout <<"                     *   *"<<endl;
    cout <<"                     *     *"<<endl;
    cout <<"                     *       *"<<endl;
    cout <<"                     *         *"<<endl;
    cout <<"                     *           *"<<endl;
    cout <<"                     *             *"<<endl;
    cout <<"                     *               *"<<endl;
    cout <<"                     *                 *"<<endl;
    cout <<"                     * * * * * * * * * * *"<<endl;

    cout <<" "<<endl;
    cout <<" "<<endl;
    cout <<" "<<endl;
    
    system("PAUSE");
    return EXIT_SUCCESS;

[Return 0]
