printing triangle pattern using for loops in c++

                                 Code to print triangle in c++

#include<iostream>
using namespace std;
int main()
{
//Double slash is used to give comment in c++ language.
int i,j,k;
for(i=0;i<7;i=i+1)
{
    for(k=20-i;k>=0;k--)  //loop for spacing
     {cout<<" ";}

    for(j=0;j<=i;j++)
     {cout<<"* ";}          //don't forget to give one space after *

cout<<endl;                  //endl move the cursor to next line

}
return(0);
}

OUTPUT:

NOTE: In the above code i used k=20-i, you can use any number in place of 20 but the number should be more than the total number of asterisk(*) present in the last line of triangle  pattern .
