下列选项的程序段中( )实现的功能是:绘制多个圆,且当x轴坐标在180到220之间的范围内,不进行圆的绘制。 A: for (y=20; y<=height; y+=a) { for (x=20; x<=width; x+=a) { if (x>=180&&x<220) { continue; } circle(x, y, d); }} B: for (y=20; y<=height; y+=a) { for (x=20; x<=width; x+=a) { if (x>=180&&x<220) { break; } circle(x, y, d); }} C: for (x=20; x<=width; x+=a) {for (y=20; y<=height; y+=a) { if (x>=180&&x<220) { continue; } circle(x, y, d); }} D: for (x=20; x<=width; x+=a) {for (y=20; y<=height; y+=a) { if (x>=180&&x<220) { break; } circle(x, y, d); }}
