hey i jst need a lil help with dis...

``````void main()
{

for(int polygon = 0;polygon < 3;polygon++)
{
int i, j;
const int max =5;
int end;
int sort;
int ymin = 21;
int start;
int ypos;
int vertices=0;

if(polygon == 0)
{
float x0[] = {20, 40, 90, 120, 70};
float x1[] = {40, 90, 120, 70, 20};
float y0[] = {20, 120, 130, 60, 90};
float y1[] = {120, 130, 60, 90, 20};

}

else if(polygon == 1)
{
float x0[] = {200, 200, 240, 300, 300, 250};
float x1[] = {200, 240, 300, 300, 250, 200};
float y0[] = {50, 80, 120, 70, 20, 60};

}

else
{
float x0[] = {400, 400, 420, 450, 450, 480, 500, 475, 445, 445};
float x1[] = {400, 420, 450, 450, 480, 500, 475, 445, 445, 400};

float y1[] = {80, 110, 110, 80, 80, 70, 20, 20, 40, 40};

}
cout << x0[vertices] << " "; <--------problem
}
}``````

da error is saying that x0 is not declared...help!!!

1. Please use [code][/code] tags when posting code - see the readme first threads.

2. void main()
main returns an int.

3. for(int polygon = 0;polygon < 3;polygon++)
This doesn't compile - polygon isn't declared. Try to post what you actually compiled.
There's no way for us to guess whether what you missed out and is causing a problem, or what you missed out just to make a shorter post.

4. cout << x0[vertices] << " "; <--------problem
Well all of your arrays go out of scope at the } which follows each if statement.

Maybe something like

``````float x0[][10] = {
{20, 40, 90, 120, 70},
{200, 200, 240, 300, 300, 250},
{400, 400, 420, 450, 450, 480, 500, 475, 445, 445}
};
cout << x0[polygon][vertices];
``````

3.

``for(int polygon = 0;polygon < 3;polygon++)``

This doesn't compile - polygon isn't declared. Try to post what you actually compiled.

was that a slip of the brain? or are you working in C90 mode today? :)

>was that a slip of the brain? or are you working in C90 mode today?

Maybe he/she was thinking about it from a .C point of view rather than a .cpp? Unless C90 is .c mode? He he
