这段代码仍然有一个问题:
在定义成员函数时,函数名后的const关键字应该放在函数参数列表的后面,而不是放在函数名后面。
修正后的代码如下:
```
class Country {
private:
char name[40], capital[40];
int population;
public:
Country(const char* cou = NULL, const char* cap = "NONE", int pop = 0);
const char* GetName() const;
const char* GetCapital() const;
int GetPopulation() const;
void Set(const char* cou = "Russia", const char* cap = "Moscow", int pop = 143000000);
void Show();
};
Country::Country(const char* cou, const char* cap, int pop) {
strcpy(name, cou);
strcpy(capital, cap);
population = pop;
}
const char* Country::GetName() const {
return name;
}
const char* Country::GetCapital() const {
return capital;
}
int Country::GetPopulation() const {
return population;
}
void Country::Set(const char* cou, const char* cap, int pop) {
strcpy(name, cou);
strcpy(capital, cap);
population = pop;
}
void Country::Show() {
cout << name << "-" << capital << "-" << population << endl;
}
```
