Question

我一直在尝试用 c ++ 进行一些编程，我无法理解这里的错误是什么。
我正在使用代码块 ide，当我运行程序我唯一的错误是

错误：'boolean'尚未声明|
|| ===构建完成：1个错误，0个警告（0分0秒）=== ||
让我知道，如果你们发现任何并让我朝着正确的方向前进的话。

确定。这是实际的代码。但我还没有完全完成。我只是中途。

#include <iostream>

using namespace std;

bool isGoodCountry(char &countryName, int numCities, int numVillages, boolean hasNuclearPower, char &continentName, char &neighborCountries){

if(1==2){

    return false;
}
return true;

}
int main()
{
    cout << "Hello world!" << endl;

    char countryName[25];
    int numCities, numVillages;
    bool hasNuclearPower;
    char continentName[25], neighborCountries[150];

    cout<<"Enter name of the Country: ";
    cin>>countryName;

    cout<<"Enter number of cities in the country: ";
    cin>>numCities;

    cout<<"Enter number of villages in the country: ";
    cin>>numVillages;

    cout<<" Does the country has Nuclear Power: ";
    cin>>hasNuclearPower;

    cout<<"Enter name of the continent: ";
    cin>>continentName;

    cout<<"Enter the neighbor countries names: ";
    cin>>neighborCountries;

    isGoodCountry(*countryName, numCities, numVillages, hasNuclearPower, *continentName, *neighborCountries);
    return 0;
}

谢谢＆amp;问候

Answer 1

bool isGoodCountry(char &countryName, int numCities, int numVillages, boolean hasNuclearPower, char &continentName, char &neighborCountries){

boolean不是一种类型;你的意思是bool。

bool isGoodCountry(char &countryName, int numCities, int numVillages, bool hasNuclearPower, char &continentName, char &neighborCountries){

Answer 2

该行

bool isGoodCountry(char &countryName, int numCities, int numVillages, boolean hasNuclearPower, char &continentName, char &neighborCountries){

是

 bool isGoodCountry(char &countryName, int numCities, int numVillages, bool hasNuclearPower, char &continentName, char &neighborCountries){

Answer 3

而不是

bool isGoodCountry(char &countryName, int numCities, int numVillages, boolean hasNuclearPower, char &continentName, char &neighborCountries)

你应该写

bool isGoodCountry(char &countryName, int numCities, int numVillages, bool hasNuclearPower, char &continentName, char &neighborCountries)

布尔值不是数据类型。数据类型是bool。

在您撰写的if声明中

if(1==2)

这是不可能的，所以函数将始终返回true，那么为什么必须使用if？

Bool尚未宣布
