#include <iostream.h>
#include <conio.h>

int main()
{
int height;
char ch;
cout << "Enter number of height: ";
cin >> height;
if(height == 3 || height==4 || height==5)
{
   cout << "enter symbol :";
   cin >> ch;
   if(ch == '*'|| ch =='#' )
       {
       for(int i = 1; i <= height; ++i)
       {
           for(int j = 1; j <= i; ++j)
           {
           cout << ch ;
           }
           cout << "\n";
           }
       }
else {
cout << "invalid ";
cout << "\n";
}

}
else {
cout << "invalid";
cout << "\n";
}
getch();
}

Enter number of height: 4 enter symbol* He Enter number of height: 3 enter symbol :# Enter number of height: 6 invalid Enter number of height: 5 enter symbol& invalid
