Im still learning c++ ,thats y i use a bunch of line of code but it exactly prints same output so i think you would't mind :)

#include <iostream>
using namespace std;

int main() {
int i,j,lines,k,num=1;
cout<<"Enter the length";
cin>>lines;
cout<<endl;
for(i=1;i<=lines;i++)
{
for(j=lines-i;j>0;j--)
{
cout<<" ";
}
for(k=1;k<=i;k++)
{
cout<<" ";
cout<<" ";
cout<<"*"<<" ";
}
cout<<endl;
}
return 0;
}
