I need to do a pyramid in C++ like this one:
*
* *
* * *
* * * *
* * * * *

buti just know how to do the figure at one side:

*
* *
* * *
* * * *
* * * * *


# include <stdio.h>
# include <math.h>

void main()
{

int count,count2;

for(count=1;count<=5;count++)
{
for(count2=1;count2<=count;count2++)
printf(" *");
printf("\n");
}
}

Can anyone help me hoy to change from the side to a pyramid form?

Please elaborate, as both pyramids look identical.

ok sorry, i did it as a pyramid but the page puts it at the corner yet. Bu i mean i just know how to do the figure that is above drawn with the *, but i ned to do it but in the pyramid form, like a triangle of the cue ball, but with base 5.

Pyramid in C++

You have to print spaces before stars.

If you draw your triangle with visible spaces, then you can count how many you need on each line, and you can programme accordingly, right?

----*
---*-*
--*-*-*
-*-*-*-*
*-*-*-*-*
So you see that there are fours spaces on the first line, three on the second, and so on.
Now you just have to translate that into your code.

.....
for(count=1;count<=5;count++)
{
/* here you need to insert 4 spaces when count==1,
3 spaces when count==2, (3=5-2)
2 spaces when count==3, (2=5-3)
1 space when count==4, (1=5-4)
0 space when count==5 (0=5-5)
get the idea?
You can do this with an additional for/next loop that runs 5-count times, each time it should print ONE space.
Try it out, if it does not work, post this part of your code.
If it works, post the result!!
*/
for(count2=1;count2<=count;count2++)
printf(" *");
printf("\n");
}

for(count=1;count<=5;count++)
{
// complete the start value and end condition for the loop, the index should increment by one
for( ; ; ){ /* here you add a printf statement that prints simply " " (a space)*/}
//
for(count2=1;count2<=count;count2++)
printf(" *");
printf("\n");

}

{

int count,count2,count1;


for(count=1;count<=5;count++)
{
for(count1=count;count1<=5;count1++)
