Question

我正在尝试访问我在头文件中声明的变量。当我尝试将像女性这样的变量分配给0时，我收到一条错误，上面写着“'女性'未在此范围内声明。”我不确定这意味着什么。我是否必须再次在.cc文件中声明该变量，即使它包含school.h？此外，我收到一个错误，我的重载赋值运算符读取“ISO C ++禁止声明'学校'没有类型，预期'，'或'...'在'＆amp;'标记之前，'bool运算符==（ int）'必须有类或枚举类型的参数。“

school.cc

使用表单ClassName :: member name定义成员。

$(document).ready(function() {
  $('input:visible:enabled:first').focus();

  /*Change button text and show loading icon*/
  $('#loginbtn').click(function() {
    var img_route = "http://www.tutorialbunch.com/photoshop/animation/images/google-loading-icon11.gif";
    $('#loginbtn').attr("disabled", true).html('<img src="' + img_route + '" style="float:left;margin-right:0.5em;" height="21" width="21"> Logging in ...');
    $(this).parents('form').submit();
  });
});

这同样适用于您的其他成员。不是你的自由运营商。
