以下会报错的是？
A: function a(x, y, z=10) {}
B: function a(x, y, z=9+1) {}
C: function a(x, x, z=11) {}
D: function a(x, y, z+1) {}
A: function a(x, y, z=10) {}
B: function a(x, y, z=9+1) {}
C: function a(x, x, z=11) {}
D: function a(x, y, z+1) {}
举一反三
- 5. Known mathematical function V = f (x, y, z), you can call the function vol_visual4d (x, y, z, V) to set the slice. ( )
- The function Y = f(X,Z) means A: X multiplied by Y equals f. B: Y is determined by both X and C: X + Y = D: none of the above.
- intx=1,y=2,z=3;以下语句执行后x，y，z的值是x=-1,y=(),z=10。X=-X;Y++;Z=int(x/Y);printf("x=%d,y=%d,z=%d ",x,y,z);
- 有下述JS代码：var x = 10; var y = 20;var z = x＜y ? x++ : ++y ;console.log( ‘x=’ + x + ‘; y=’ + y + ‘; z=’ + z);其运行结果是（ ） A: x=11; y=20; z=11 B: x=11; y=21; z=10 C: x=11; y=21; z=11 D: x=11; y=20; z=10
- 已知int x=1,y=2,z=3;以下语句执行后x,y,z的值是( ). if(x>y) z=x; x=y; y=z; A: x=1, y=2, z=3 B: x=2, y=3, z=3 C: x=2, y=3, z=1 D: x=2, y=3, z=2
