Hi All,

Can someone look at this code and tell me how I may use the Array (CPoint point) to draw the lines based on user input in text box. The program works fine without the array right now. I want to try to use an Array instead. I'm trying to learn other ways of displaying graph lines. This code was generated using AppWizard in VC 60++.

Thanks

```
void CProject5View::OnDraw(CDC* pDC)
{
double PI = 3.1415926535;
int x, y = 0;
int i = 0;
double dStep = (PI * 2) / m_iSamples;
double dResult = i * dStep;
pDC->MoveTo(60, 200);
pDC->LineTo(60, 400);
pDC->LineTo(550, 400);
pDC->MoveTo(60, 400);
pDC->LineTo(60, 600);
//**************** ARRAY CPOINT ***********************
CPoint point[8]; {
point[0] = (PI/4 * x, 0.707 * y);
point[1] = (PI/2 * x, 1 * y);
point[2] = ((3*PI)/4 * x, 0.707 * y);
point[3] = (PI * x, 0 * y);
point[4] = ((5*PI)/4 * x, -0.707 * y);
point[5] = ((3*PI)/2 * x, -1 * y);
point[6] = ((7*PI)/4 * x, -0.707 * y);
point[7] = (2*PI * x, 0 * y);
}
int PtX = 60;
int PtY = 400;
int xLine = 500 / m_iSamples;
switch (m_Graph) {
case Sin:
pDC->MoveTo(PtX,PtY);
for(i=0; i<=m_iSamples; i++) {
dResult = i*dStep;
dResult = sin(dResult);
dResult = 200 * dResult;
y = (int)dResult;
y = PtY - y;
x = PtX + i * xLine;
pDC->LineTo(x,y);
}
break;
case Cos:
pDC->MoveTo(PtX, PtY - 200);
for(i=0; i<=m_iSamples; i++) {
dResult = i*dStep;
dResult = cos(dResult);
dResult = 200 * dResult;
y = (int)dResult;
y = PtY - y;
x = PtX + i * xLine;
pDC->LineTo(x,y);
}
break;
}
