Flowchart to make such a pattern like a pyramid
C++ Program (Source Code) to make such a pattern like a pyramid
#include<iostream>
using namespace std;
int main()
{
int r,sp,disp,n,no;
cout<<"Please enter the number of rows";
cin>>no;
n=no;
r=1;
do
{
sp=1;
do
{
cout<<" ";
sp++;
}
while(sp<=n);
n--;
disp=1;
do
{
cout<<" "<<r;
disp++;
}
while(disp<=r);
cout<<endl;
r++;
}
while(r<=no);
}
Output
