Comp Sci How to Modify C++ Code to Create a Center-Aligned Pyramid?

[Naldo6]

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.

 

[Naldo6]

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.

 

[Borek]

You have to print spaces before stars.

 

[Naldo6]

ok, and howi do that?...

 

[Naldo6]

how i do that in my code above ?

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 teh 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...

 

[mathmate]

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");

}
}

 

[mathmate]

Congratulations!

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...
