已知float x=2.23,y=4.35;,根据下面的输出结果,正确的程序段是()。x=2.230000,y=4.350000 y+x=6.58,y-x=2
A.printf(“x=%8.2f,y=%8.2f”,x,y); printf(“y+x=%4.2f,y-x=%4.2f”,y+x,y-x) B.printf(“x=%8.6f,y=%8.6f”,x,y); printf(“y+x=%4.2f,y-x=%4.2f”,y+x,y-x) C.printf(“x=%7.2f,y=%7.2f”,x,y); printf(“y+x=%3.2f,y=%3.2f”,y+x,y-x) D.printf(“x=%f,y=%f”,&x,&y); printf(“y+x=%f,y=%f”,y+x,y-x)
