使用setw（）的格式化（）C++

Question

我想創建一個有組織的看圖，每個食物在每個月下的金額。我能排隊第一排，但在此之後，一些事情開始了。這是我結束了：Current Output

這是我試着用setw（）玩的代碼，但我似乎無法改變它的數字後，它放出第一個數組元素。

void sales_report() 
{ 
for (int i = 0; i < 7; i++) 
{ 
    cout << setw(17) << months[i] << " "; 
} 

cout << endl << foods[0] << " "; 
for (int i = 0; i < 6; i++) 
{ 
    sumapple += apples[i]; 
    cout << setprecision(2) << fixed << setw(8) << money << apples[i] << " "; 
} 
cout << setprecision(2) << fixed << setw(8) << money << sumapple << endl; 
cout << foods[1] << " "; 

for (int i = 0; i < 6; i++) 
{ 
    sumoranges += oranges[i]; 
    cout << setprecision(2) << fixed << setw(7) << money << oranges[i] << " "; 
} 
cout << setprecision(2) << fixed << setw(7) << money << sumoranges << endl; 
cout << foods[2] << " "; 

for (int i = 0; i < 6; i++) 
{ 
    sumpears += pears[i]; 
    cout << setprecision(2) << fixed << setw(10) << money << pears[i] << " "; 
} 
cout << setprecision(2) << fixed << setw(10) << money << sumpears << endl; 
cout << foods[3] << " "; 

for (int i = 0; i < 6; i++) 
{ 
    sumtomatoes += tomatoes[i]; 
    cout << setprecision(2) << fixed << setw(7) << money << tomatoes[i] << " "; 
} 
cout << setprecision(2) << fixed << setw(7) << money << sumtomatoes << endl; 
cout << foods[4] << " "; 

for (int i = 0; i < 6; i++) 
{ 
    sumcherries += cherries[i]; 
    cout << setprecision(2) << fixed << setw(6) << money << cherries[i] << " "; 
} 
cout << setprecision(2) << fixed << setw(6) << money << sumcherries << endl << totalmonth; 
for (int i = 0; i < 6; i++) 
{ 
    total = apples[i] + oranges[i] + pears[i] + tomatoes[i] + cherries[i]; 
    cout << setprecision(2) << fixed << setw(9) << money << total << " "; 
} 

}

您在每個for循環使用不同的std::setw()值。因此錯位。使用相同的值。
