Hi Pete
this is my code so far what i'm having trouble with is that the pyramid code
has to include 2 for loops. But i just can't display the lines individually
with out using cout all the time. If you can just give me some pointers as
to what i'm doing wrong as I can't copy anyones code.
Cheers
Nicolla
#include <iostream> //For cin, cout
#include <iomanip> //For setw()
using namespace std;
const maxLines = 20;
const maxColumns = 1;
void main (void)
{
int line=0;
int numCarats =0;
char carat ='^';
cout <<"\n\n\n"; //Move down the screen 3 lines
cout <<setw(40) <<carat <<endl; //Define where to start with the display
// while (numCarats <= 19) numCarats !=19; numCarats++)
// {
// cout <<'^';
// }
for (line = 4;line < 16; ++line) //number of lines to be displayed
{
//width for column
cout.width (40);
//position left side characters within the column
cout <<setw(39) <<carat <<resetiosflags(ios::left)<< setw(1) <<carat;
//Fill the left side, allows blank space to be entered before the carat
amount entered
//This allows for the carats to be right justified
cout.fill (' ');
cout <<carat <<endl;
cout <<setw(38) <<carat <<resetiosflags(ios::left)<< setw(1) <<carat ;
cout.fill (' ');
cout <<carat <<endl;
}
}
