如何修复错误：无法将“char*”转换为“FILE*”？

Question

我在这段代码中遇到了这个问题，当我编译时，在函数 gets 中向我显示错误，这说明我可以将 gets 更改为 getw，但是当我再次执行此操作时，机器向我显示错误。我用C++14

#include<iostream>

using namespace std;

class Maleta{
    
    private:
    
    char *color;                 //declaracion de variables ---documentando
    char *material;
    char *marca;
    int precio;
    
    public:
        
    void entrada (void);     //Declaracion de metodos
    void proceso (void);
    void salida (void);
    
    
};

void Maleta::entrada()
{
    
    cout<<"de color "<<endl;
    gets(color);
    cout<<"de material"<<endl;
    gets(material);
    cout<<"de marca"<<endl;
    gets(marca);
    cout<<"de precio"<<endl;
    cin>>precio;
    
}

void Maleta::salida(void)
{
    cout<<"color :"<<color<<endl;
    cout<<"material :"<<material<<endl;
    cout<<"marca :" <<marca<<endl;
    cout<<"precio :"<<precio<<endl;
    
}

int main()
{
    Maleta morral;
    morral.entrada();
    morral.salida();
    
    
}`

我想用函数 gets 修复错误。

Answer 1

gets()

函数已被弃用，不应使用。通过使用 C++ 字符串和

getline

，您可以让您的生活变得更加轻松。这是代码的固定版本：

#include <iostream>
#include <string>

using namespace std;

class Maleta {
    private:
    string color;   // I changed these to C++ strings
    string material;
    string marca;
    int precio;

    public:
    void entrada(void);
    void proceso(void);
    void salida(void);
};

void Maleta::entrada() {
    cout << "de color " << endl;
    getline(cin, color); //Note that instead of gets, we are using getline for these strings
    cout << "de material" << endl;
    getline(cin, material);
    cout << "de marca" << endl;
    getline(cin, marca);
    cout << "de precio" << endl;
    cin >> precio; //We can keep your use of cin for precio since it is an int
    cin.ignore(); // Clear newline from the buffer
}

void Maleta::salida(void) {
    cout << "color :" << color << endl;
    cout << "material :" << material << endl;
    cout << "marca :" << marca << endl;
    cout << "precio :" << precio << endl;
}

int main() {
    Maleta morral;
    morral.entrada();
    morral.salida();
}
