在'{'标记错误之前预期的primary-expression

Question

Followed codes runs properly with Eclipse but when i run on Dev C++ IDE i am getting followed error;

City.cpp:6: error: expected primary-expression before '{' token

City.h

#include <string>

using namespace std;

#ifndef CITY_H
#define CITY_H

class City
{
    public:
        City();
        string arrCity[10];
};

#endif // CITY_H

City.cpp

#include <string>
#include "City.h"

City::City()
{
    arrCity[10] = {"Tbilisi", "Batumi", "Kutaisi", "Gori", "Poti"};        
}

Answer 1

arrCity[10] = {"Tbilisi", "Batumi", "Kutaisi", "Gori", "Poti"}; doesn't do what you expected. It's trying to assign arrCity[10] (ie a std::string ) by a braced initializer list; that won't work. And it's getting out of the bound of the array.

Note that array can't be assigned directly, you can use member intializer list to initialize it like:

City::City() : arrCity {"Tbilisi", "Batumi", "Kutaisi", "Gori", "Poti"}
{
}

or use default member initializer:

class City
{
    public:
        City();
        string arrCity[10] = {"Tbilisi", "Batumi", "Kutaisi", "Gori", "Poti"};
        // or
        string arrCity[10] {"Tbilisi", "Batumi", "Kutaisi", "Gori", "Poti"};
};

Note that both the above solutions needs C++11 supports, otherwise, you might need to assign every element one by one in the constructor's body.
