c++ - 使用精度规则 c++ 排列表格

Question

我只是想让我的控制台看起来像所附图片。试图左对齐，或类似的东西使时间和速度更符合表格。请帮我弄清楚我需要做什么，才能使我的输出看起来与所附图片完全一样。

#include <iostream>
#include <iomanip>

using namespace std;


int main(void)

{

    char RacerName [20];
    int checkPointOneTime;
    int checkPointTwoTime;
    int checkPointThreeTime;
    int checkPointFourTime;
    int finishTime;


    cout << "Enter the racer's first name: ";
    cin >> RacerName;
    cout << "Enter the time (in minutes) at Check Point 1: ";
    cin >> checkPointOneTime;
    cout << "Enter the time (in minutes) at Check Point 2: ";
    cin >> checkPointTwoTime;
    cout << "Enter the time (in minutes) at Check Point 3: ";
    cin >> checkPointThreeTime;
    cout << "Enter the time (in minutes) at Check Point 4: ";
    cin >> checkPointFourTime;
    cout << "Enter the time (in minutes) at the Finish Line: ";
    cin >> finishTime;

    cout << "\nLOTOJA After Action Review for John" << endl << endl;

    cout << setw(24) << "Interval Details" << endl << endl;

    int checkPointOneDistance = 44;
    int checkPointTwoDistance = 87;
    int checkPointThreeDistance = 128;
    int checkPointFourDistance = 165;
    int checkPointFinalDistance = 207;

    int checkPointOneInterval = checkPointOneDistance;
    int checkPointTwoInterval = checkPointTwoDistance - checkPointOneDistance;
    int checkPointThreeInterval = checkPointThreeDistance - checkPointTwoDistance;
    int checkPointFourInterval = checkPointFourDistance - checkPointThreeDistance;
    int checkPointFiveInterval = checkPointFinalDistance - checkPointFourDistance;

    int checkPointTimeOneInterval = checkPointOneTime;
    int checkPointTimeTwoInterval = checkPointTwoTime - checkPointOneTime;
    int checkPointTimeThreeInterval = checkPointThreeTime - checkPointTwoTime;
    int checkPointTimeFourInterval = checkPointFourTime - checkPointThreeTime;
    int checkPointTimeFiveInterval = finishTime - checkPointFourTime;

    float minutesInHours = 60.0;

    float speedIntervalOne = checkPointOneDistance / (checkPointTimeOneInterval / minutesInHours);
    float speedIntervalTwo = checkPointTwoInterval / (checkPointTimeTwoInterval / minutesInHours);
    float speedIntervalThree = checkPointThreeInterval / (checkPointTimeThreeInterval / minutesInHours);
    float speedIntervalFour = checkPointFourInterval / (checkPointTimeFourInterval / minutesInHours);
    float speedIntervalFive = checkPointFiveInterval / (checkPointTimeFiveInterval / minutesInHours);


    cout << setw(11) << "Location" << setw(17.5) << " Distance" << setw(16.5) << " Time" << setw(18) << " Speed" << endl;
    cout << "Interval 1" << setfill('.') << setw(16) << checkPointOneInterval << setfill (' ') << setw(16.5) << checkPointTimeOneInterval << setw(20) << setprecision(3) << fixed << speedIntervalOne << endl;
    cout << "Interval 2" << setfill('.') << setw(16) << checkPointTwoInterval << setfill(' ') << setw(16.5) << checkPointTimeTwoInterval <<  setw(20) << setprecision(3) << speedIntervalTwo << endl;
    cout << "Interval 3" << setfill('.') << setw(16) << checkPointThreeInterval << setfill(' ') << setw(16.5) << checkPointTimeThreeInterval << setw(20) << setprecision(3) << speedIntervalThree << endl;
    cout << "Interval 4" << setfill('.') << setw(16) << checkPointFourInterval << setfill(' ') << setw(16.5) << checkPointTimeFourInterval << setw(20) << setprecision(3) << speedIntervalFour << endl;
    cout << "Interval 5" << setfill('.') << setw(16) << checkPointFiveInterval << setfill(' ') << setw(16.5) << checkPointTimeFiveInterval << setw(20) << setprecision(3) << speedIntervalFive << endl;

    int totalRaceCheckPoints = 5;
    float totalAverageSpeed = checkPointFinalDistance / static_cast<float>(finishTime / minutesInHours);

    cout << "\nThe average speed for the entire course was " << totalAverageSpeed << " mph. " << endl << endl;

    return 0;

}

看起来你只需要在实际距离数字和时间数字之间输入另一个空格

像这样把你的 16.5 改成 17.5

cout << setw(11) << "Location" << setw(17.5) << " Distance" << setw(16) << " Time" << setw(18) << " Speed" << endl;
cout << "Interval 1" << setfill('.') << setw(16) << checkPointOneInterval << setfill(' ') << setw(17.5) << checkPointTimeOneInterval << setw(20) << setprecision(3) << fixed << speedIntervalOne << endl;
cout << "Interval 2" << setfill('.') << setw(16) << checkPointTwoInterval << setfill(' ') << setw(17.5) << checkPointTimeTwoInterval << setw(20) << setprecision(3) << speedIntervalTwo << endl;
cout << "Interval 3" << setfill('.') << setw(16) << checkPointThreeInterval << setfill(' ') << setw(17.5) << checkPointTimeThreeInterval << setw(20) << setprecision(3) << speedIntervalThree << endl;
cout << "Interval 4" << setfill('.') << setw(16) << checkPointFourInterval << setfill(' ') << setw(17.5) << checkPointTimeFourInterval << setw(20) << setprecision(3) << speedIntervalFour << endl;
cout << "Interval 5" << setfill('.') << setw(16) << checkPointFiveInterval << setfill(' ') << setw(17.5) << checkPointTimeFiveInterval << setw(20) << setprecision(3) << speedIntervalFive << endl;
