--description--

*=操作符是让变量与一个数相乘并赋值。

myVar = myVar * 5;

变量myVar等于自身与数值5相乘的值。也可以写作这样的形式:

myVar *= 5;

--instructions--

使用*=操作符实现同样的效果。

--hints--

a应该等于25

assert(a === 25);

b应该等于36

assert(b === 36);

c应该等于46

assert(c === 46);

应该对每个变量使用*=操作符。

assert(code.match(/\*=/g).length === 3);

不要修改注释上面的代码。

assert(
  /var a = 5;/.test(code) &&
    /var b = 12;/.test(code) &&
    /var c = 4\.6;/.test(code)
);

--seed--

--after-user-code--

(function(a,b,c){ return "a = " + a + ", b = " + b + ", c = " + c; })(a,b,c);

--seed-contents--

var a = 5;
var b = 12;
var c = 4.6;

// Only change code below this line
a = a * 5;
b = 3 * b;
c = c * 10;

--solutions--

var a = 5;
var b = 12;
var c = 4.6;

a *= 5;
b *= 3;
c *= 10;
