举一反三
- 有代码片段:function f(y) {var x=y*y;return x;} for(var x=0;x< 5;x++) {y=f(x);document.writeln(y);}输出结果是( )。 A: 0 1 2 3 4 B: 0 1 4 9 16 C: 0 1 4 9 16 25 D: 0 1 2 3 4 5
- 阅读下面的JavaScript代码,输出结果是function f(y) {var x=y*y;return x;}for(x=0;x<; 5;x++) {y=f(x);document.writeln(y);} A: 0 1 4 9 16 25 B: 0 1 2 3 4 C: 答案都不对 D: 0 1 4 9 16
- 【简答题】设 A = , B = (1) 计算 3 A - B , 2 A +3 B ; (2) 若 X 满足 A + X = B ,求 X ; (1) 若 Y 满足( 2 A - Y ) +2 ( B - Y ) =0 ,求 Y . (30.0分)
- 阅读下面的JavaScript代码,执行结果为?function f(y) { var x = y * y; return x;}for(x = 0; x < 5; x++) { y = f(x); document.write(y+" ");} A: 0 1 2 3 4 B: 0 1 4 9 16 C: 0 1 4 9 16 25 D: 以上答案都不对
- Read the following JavaScript code: function f(y) { var x=y*y; return x; } for(x=0;x< 5;x++) { y=f(x); document.writeln(y); } The output is ( ). A: 01 2 3 4 B: 0 1 4 9 16 C: 0 1 4 9 16 25 D: None of the above answers are correct
