推荐答案

c ++是带对象扩展的C，所以学习C语言基础知识是个好主意。

c++ is C with object extension, so it is a good idea to learn C language basics.

尝试：

Try:

if (a >= b && a <= c)
   {
   DoSomething(1);
   }
else
   {
   DoSomething(2);
   }

&& 运算符不能替换 else 子句。相反，它等同于嵌套的 if 语句，例如

The && operator cannot replace the else clause. Instead, it is equivalent to nested if statements, e.g.

if (a > b && a > c)
{
  // do something
}

相当于

is equivalent to

if (a > b)
{
  if (a > c)
  {
    // do something
  }
}
