for loops are confusing me

[trprince]

So i'm trying to print this flag still that is a rectangle with an x going from end to end using a W for white spaces and --- for the X since it always has to be the width of the X. here is what i have so far and i can't figure out what to do to ge the other half.

for(lineColor = 0; lineColor < flagSize; lineColor++){                                 
          for(lineColor2 = 0; lineColor2 < lineColor; lineColor2++){                           
             printf("W");                                                                      
          }                                                                                    
          printf("---\n");                                                                     
        }

and then the other thing is printing triangles sort. well I'm trying to have something like this
------GGGGGGGGGGGGGGGGG
----------------GGGGGGGGGGGG
--------------------------GGGGGG
-------------------------------------

so far i have this

midPoint = (flagSize / 2) + 1;                                                          
       incrementSize = flagWidth / midPoint;                                                   
                                                                                               
       for(lineCntr = 1; lineCntr < midPoint; lineCntr++){                                     
          for(centerColor = 0;centerColor < lineCntr; centerColor++){                          
             printf("-");                                                                      
             printf("G");                                                                      
          }                                                                                    
          printf("\n");                                                                        
       }

what about something like

int width=10;
	int height=10;
	int i,j;
	for(i=0;i<=height;i++)
	{
		for(j=0;j<=width;j++)
		{
			if((i==j)||((height-i)==(j))) printf("W");
			else printf(" ");
		}
	printf("\n");
	}
