Answer 1

edit: implemented in c++

#include <iostream>
using namespace std;

int main() {

int i,j;

int input = 4;
for (i = 0; i<input ; i++){

for(j= 0;j<input;j++){

if(j >= (input-i-1))
{ cout << "#"; }
else{ cout << "quot;; } /*use spaces here instead of $ to run on terminal... use $ to run on soloLearn*/

}
cout << endl ;
}

return 0;
}

Answer 2

#include <iostream>
using namespace std;

int main()
{
int i,j,n;
cout<<"Enter Input:\n";
cin>>n;
for(i=0;i<n;i++)
{
for(j=0;j<n;j++)
{
if(j>=(n-i-1))
{
cout<<"#";
}
else
{
cout<<" ";
}
}
cout<<"\n";
}
return 0;
}

Answer 3

you r welcome shahbaz ,
in those for loops if you initialize i = j = 1 then use '<=' condition in both loops and change the if condition 'if( j>= input -i)'

Answer 4

Loops are the most interesting topic I've encountered till yet.

Answer 5

Thank you Kabira, just had to put a '<=' in the first loop.

Answer 6

Got you... ^_^
