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?

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.
 
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.
 
ok, i know that ther i need always four spaces in each line but i don't know how to put that in codes for run my programs perfectly...i just know how to put all the * to begin at the left corner...that the problem

can u help me more?...
 
...
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");
}
...
 
Do you mean that right?...

but i don't know how to state the instruction of the spaces in that for between the other two for...
help me a little more please

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

void main()
{

int count,count2;

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

}
}
 
i don't know how to do this:

You can do this with an additional for/next loop that runs 5-count times, each time it should print ONE space.

i have just discuss in my class the instruction for no more than that...
 
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");

}
 
ty... i sucees with my pyramid i get the correct code

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

void main()
{

int count,count2,count1;


for(count=1;count<=5;count++)
{
for(count1=count;count1<=5;count1++)
printf(" ");
for(count2=1;count2<=count;count2++)
printf(" *");
printf("\n");

}
}
 
ty... i will need your help durng the rest of the semester... i have another homeworks.. i will begin on the week so i will request your help... a lot of thanks...
