Here I’ve shared various star, triangle, pyramids patterns and shapes in C++ using asterisks, numbers, alphabets etc. These are simple program which require basic programming knowledge.
Examples to print half pyramid, pyramid, inverted pyramid, Pascal’s Triangle and Floyd’s triangle in C++ Programming using control statements.
Printing these patterns is not easy if you don’t have basic idea of using different loops, once you get a basic idea of these pattern programs shared below, you can make any pattern or shape instantly. Hope you find these useful and keep commenting for the new patterns and shapes you want me to upload for everyone’s help.
Following are the various Patterns and shapes in C++:
1. C++ Program To display the half pyramid of *, numbers and character.
*
* *
* * *
* * * *
* * * * *
#include <iostream>
using namespace std;
int main()
{
int i,j,rows;
cout<<"Enter the number of rows: ";
cin>>rows;
for(i=1;i<=rows;++i)
{
for(j=1;j<=i;++j)
{
cout<<"* ";
}
cout<<"\n";
}
return 0;
}
2. C++ Program to print half pyramid as using numbers as shown in figure below.

cout<<"Enter the number of rows: ";
cin>>rows;
for(i=1;i<=rows;++i)
{
for(j=1;j<=i;++j)
{
cout<<j<<" ";
}
cout<<"\n";
}
return 0;
}
3. C++ Program to print triangle of characters as below:
A
B B
C C C
D D D D
E E E E E
#include <iostream>
using namespace std;
int main()
{
int i,j;
char input,temp='A';
cout<<"Enter uppercase character you want in triangle at last row: ";
cin>>input;
for(i=1;i<=(input-'A'+1);++i)
{
for(j=1;j<=i;++j)
cout<<temp<<" ";
++temp;
cout<<endl;
}
return 0;
}
4. C++ Program to print inverted half pyramid using * as shown below:
* * * * *
* * * *
* * *

#include <iostream>
using namespace std;

cout<<"Enter the number of rows: ";
cin>>rows;
for(i=rows;i>=1;--i)
{

oh, not that . the 2’s are all align.
all example is very simple & easy but some example explain is complicated way
congrats for your support in programming,,,,,,,can i get a code to draw the shape of a star using asteriks
can you please explain what type of star?
Admin plz make this.. *****

Sorry cannot understand your pattern. Please write from next line.
Please help
Insert uppercase character:E
E D C B A B C D E
D C B A B C D
C B A B C
B A B

A is vertical align. Pattern should be like inverted pyramid
Use 8th program above. Just take a variable as
ascii value of ‘A’ and increment or decrement it accordingly
