C++ 对初始化时使用的未初始化局部变量感到困惑？

当我确信我已经初始化时，我得到一个未初始化的局部变量错误。错误读取正在使用的未初始化局部变量wk1，它是wk1-wk5

代码如下：

#include <iostream>

using namespace std;

const double tax = 0.14;

int main()
{   

    int wk1,wk2,wk3,wk4,wk5;
    wk1,wk2,wk3,wk4,wk5 = 0;

    int thours = wk1 + wk2 + wk3 + wk4 + wk5; <------------ This is the error line.
    thours = 0;

    double payrate;
    payrate = 0;

    double gross = thours * payrate;
    double taxes = tax * gross;
    double net = gross - taxes;
    double clothes = 0.10 * net;
    double supplies = 0.10 * net;
    double remaining = net - clothes - supplies;
    double bonds = 0.25 * remaining;
    double pbonds = 0.50 * bonds;

    bonds = 0;
    gross = 0;
    net = 0;
    clothes = 0;
    supplies = 0;
    remaining = 0;

    cout << "Please enter the payrate for employee." << endl;
    cin >> payrate;
    payrate = 0;

cout << "Please enter employee's total hours for week one:" << endl;
cin >> wk1;
wk1 = 0;

    cout << "Please enter employee's total hours for week two:" << endl;
    cin >> wk2;
    wk2 = 0;

    cout << "Please enter employee's total hours for week three:" << endl;
    cin >> wk3;
    wk3 = 0;

    cout << "Please enter employee's total hours for week four:" << endl;
    cin >> wk4;
    wk4 = 0;

    cout << "Please enter employee's total hours for week five:" << endl;
    cin >> wk5;
    wk5 = 0;

    cout << "Here is income before taxes: " << gross << endl;
    cout << "Here is income after taxes: " << net << endl;
    cout << "Here is clothes and accesories: " << clothes << endl;
    cout << "Here is School supplies: " << supplies << endl;
    cout << "Here is personal bonds: " << bonds << endl;
    cout << "Here is parents bonds: " << pbonds << endl;

    return 0;
}

此行是一个逗号运算符表达式，相当于：

wk5 = 0;

因为像wk1这样的表达式没有副作用。只有变量wk5被赋值，其他变量仍未初始化。你可以做：

wk1 = wk2 = wk3 = wk4 = wk5 = 0;

谢谢你修复了我的问题，但是现在我的所有输出计算都得到了0。您是否看到可以有效地获取值的方法？@user3312523语句，如double gross=thours*payrate；不会永远绑定变量的值。在获得thours和payrates的有效值之后，您需要计算gross的值。@user3312523:每次cin>>调用后，您都会将该变量重置为零。只需删除这些电话。例如：在代码cin>>wk1中；wk1=0；删除最后一行wk1=0；一切都会好起来的。致以最良好的祝愿。好的@Yu Hao，我不明白你在得到这些值后计算它的确切含义。当我去掉cin>>wk1=0时，我所有的计算结果仍然是0；还有其他的。谢谢你解决了我的问题，但是现在我的所有输出计算都得到了0。您是否看到可以有效地获取值的方法？@user3312523语句，如double gross=thours*payrate；不会永远绑定变量的值。在获得thours和payrates的有效值之后，您需要计算gross的值。@user3312523:每次cin>>调用后，您都会将该变量重置为零。只需删除这些电话。例如：在代码cin>>wk1中；wk1=0；删除最后一行wk1=0；一切都会好起来的。致以最良好的祝愿。好的@Yu Hao，我不明白你在得到这些值后计算它的确切含义。当我去掉cin>>wk1=0时，我所有的计算结果仍然是0；还有其他人。
