This program is meant to display an arrowhead like this, see the bottom of the code for what the arrowhead is suppose to look like.


But im having trouble getting it to display and arrow head, when i run the program it looks like this

cout << "Rendering Arrow...\n" << endl;

cout << "\t\t+" << endl;
cout << "\t" << "\\\t++" << endl;
cout << "\t-++++++++++" << endl;
cout << "\t/\t++" << endl;
cout << "\t\t+" << endl;

Divide it into three parts .
First part
****+
****++
****+++

Second part
+++++++

Third part
****+++
****++
****+


Make three loops for making the three parts separately.
Substitute asterisk with " "(space).

You have not put space anywhere in your code .
Try using 
 
 
 cout << "  ";

Hope that helps!!

i got the first and third part, how would i make the for loop for the 2nd part
Raman009 (124)
simply add the number of spaces and the arrows in the line below +1
In the above case , it would be 4 + 3 + 1 = 8

for(int i=0 ; i<8;i++){
  cout << "+" ;
}
cout << endl;

//For first part
for(int i=0 ; i<3;i++){
   //For spaces
      int k=0;
      while(k<4){
            cout << " ";
             k++; 
      }
   //For + sign
   for(int j=0 ; j<=i ; j++){
       cout << "+";
   }
   cout << endl;
}

//For middle part
....try on your own

//For third part
...try on your own


Try writing comments while making patterns as to what each part is supposed to do . It will help you to understand it later.
