Question

我正在尝试编译这个，但我收到错误error: ‘setioflags’ was not declared in this scope，这听起来像是试图将其识别为变量。这是我直接从我的教科书中复制的例子，多次检查并且找不到错误。我忽略了什么吗？我在Mac上如果有所作为，我知道<conio.h>库不起作用，但<iomanip>被识别

#include <iostream>
#include <iomanip>
using namespace std;

const int DISTRICTS = 4;
const int MONTHS   = 3;

int main() {
int d, m;
double sales[DISTRICTS][MONTHS];

cout << endl;
for(d = 0; d < DISTRICTS; d++)
    for(m = 0; m < MONTHS; m++)
    {
        cout << "Enter sales for district " << d+1;
        cout << ", month " << m+1 << ": ";
        cin >> sales[d][m];
    }

cout << "\n\n";
cout << "                       Month\n";
cout << "               1       2       3";
for(d = 0; d < DISTRICTS; d++)
{
    cout << "\nDistrict " << d+1;   
    for(m = 0; m < MONTHS; m++)         // Display array values
        cout << setiosflags(ios::fixed) // Not exponential
        << setioflags(ios::showpoint)   // Always use poin
        << setprecision(2)              // Digits to right
        << setw(10)                     // Field width
        << sales[d][m];                 // Get number from array
}   // end for(d)
cout << endl;
return 0;
 }

您正在寻找setiosflags。请注意其中的额外 s 。你的拼写在第二次通话时有所不同。

Setiosflags无法识别
