minimumCountry函数输入和输出不正确

Question

此代码正在查看分隔文件并查找总面积最小的国家/地区，我为字符串制作了两组定义以便进行比较。代码输出的是maximumCountry函数而不是最小的国家/地区的信息。

while (!in.fail())
{
    if (minArea == 0 || Area < minArea)
    {
        readRecord(in, ISO2, ISO32, ISONumeric2, fips2, Country2, Capital2,
            Area2, Population2, Continent2, tld2, CurrencyCode2, CurrencyName2, Phone2,
            PostalCodeForm2, PostalCodeRegex2, Languages2, geonameid2, neighbors2,
            EquivalentFipsCode2);

        minArea = Area2;
    }
    else {
        readRecord(in, ISO, ISO3, ISONumeric, fips, Country, Capital,
            Area, Population, Continent, tld, CurrencyCode, CurrencyName, Phone,
            PostalCodeForm, PostalCodeRegex, Languages, geonameid, neighbors,
            EquivalentFipsCode);
    }
}

Answer 1

猜测因为我们缺少很多的信息：

// some init of Area & minArea here

while (!in.fail()) {
    if (Area < minArea) {
        minArea = Area;
    }
    readRecord(in, ISO, ISO3, ISONumeric, fips, Country, Capital,
        Area, Population, Continent, tld, CurrencyCode, CurrencyName, Phone,
        PostalCodeForm, PostalCodeRegex, Languages, geonameid, neighbors,
        EquivalentFipsCode);

}
