C++ Can';t似乎无法精确地排列十进制数字
我有一个简单的程序,询问一部电影的名称,以及set1和set2的门票销售量。然后用这些值进行计算并显示结果。我唯一的问题是,我似乎无法按照我希望的方式排列十进制值 控制台中的最后三行输出应该一直是这样的(美元符号和小数点对齐):。但是当我为票证的集合1输入1,为票证的集合2输入0,反之亦然,它看起来是这样的:。关于如何使输出始终像第一个屏幕截图中那样排列整齐,有什么想法吗?提前谢谢C++ Can';t似乎无法精确地排列十进制数字,c++,input,io,iomanip,C++,Input,Io,Iomanip,我有一个简单的程序,询问一部电影的名称,以及set1和set2的门票销售量。然后用这些值进行计算并显示结果。我唯一的问题是,我似乎无法按照我希望的方式排列十进制值 控制台中的最后三行输出应该一直是这样的(美元符号和小数点对齐):。但是当我为票证的集合1输入1,为票证的集合2输入0,反之亦然,它看起来是这样的:。关于如何使输出始终像第一个屏幕截图中那样排列整齐,有什么想法吗?提前谢谢 #include <iostream> #include <string>

我想你的问题是你在设定美元符号的宽度,而不是你的数字
这似乎为我解决了问题:
#include <iostream>
#include <string>
#include <iomanip>
using namespace std;
int main() {
string film = "";
int set1 = 0;
int set2 = 0;
// the cinema always takes this 20% cut.
const double CINEMA_FEE = 0.20;
double profit = 0;
double profitMinusFee = 0;
double paidToMovieMaker = 0;
cout << "What is the name of the film: ";
getline(cin, film);
cout << "How many tickets for set1 sold: ";
cin >> set1;
cout << "How many tickets for set2 sold: ";
cin >> set2;
cout << "Film Name:" << setw(20) << "\"" << film << "\"" << endl;
cout << "Set1 tickets sold:" << setw(16) << set1 << endl;
cout << "Set2 tickets sold:" << setw(16) << set2 << endl;
set1 *= 10;
set2 *= 6;
profit = set1 + set2;
profitMinusFee = profit * CINEMA_FEE;
paidToMovieMaker = profit - profitMinusFee;
// needs to always show two decimal points and fixed

你能搞定吗?这么简单,但我错过了!谢谢你,先生。
