C++货币输出

我现在正在学习 C++ 课程，并已完成期末作业。然而，有一件事困扰着我：

虽然我有正确的输出来测试特定的输出，basepay应该133.20它显示为133.2。有没有办法让它显示额外的 0 而不是将其保留？

有人知道这是否可能以及如何做到吗？先感谢您

我的代码如下：

cout<< "Base Pay .................. = " << basepay << endl;
cout<< "Hours in Overtime ......... = " << overtime_hours << endl;
cout<< "Overtime Pay Amount........ = " << overtime_extra << endl;
cout<< "Total Pay ................. = " << iIndividualSalary << endl;
cout<< endl;

cout<< "%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%" <<endl;
cout<< "%%%% EMPLOYEE SUMMARY DATA%%%%%%%%%%%%%%%%%%%%%%%" <<endl;
cout<< "%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%" <<endl;
cout<< "%%%% Total Employee Salaries ..... = " << iTotal_salaries <<endl;
cout<< "%%%% Total Employee Hours ........ = " << iTotal_hours <<endl;
cout<< "%%%% Total Overtime Hours......... = " << iTotal_OvertimeHours <<endl;
cout<< "%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%" << endl;
cout<< "%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%" << endl;

如果你想用C++的方式来做，and您可以使用 C++11 标志进行编译，您可以使用标准库：

// Note: the value in cents!
const int basepay = 10000;

// Create a stream and imbue it with the local configuration.
std::stringstream ss;
ss.imbue(std::locale(""));

// The stream contains $100.00 (assuming a en_US locale config)
ss << std::showbase << std::put_money(basepay);

Example here.

这种方法有什么优点？

• 它使用本地配置，因此输出在任何机器上都是一致的，即使是小数分隔符、千位分隔符、货币符号和小数精度（如果需要）。
• 所有格式工作都已由 std 库完成，需要做的工作更少！
