Class/Object Help

#include <iostream>

using namespace std;

class HelloClass(){ //*Error: expected unqualified -id before ')' token
public:
void saying(){
cout <<"hi" <<endl;
}
};

int main(){
HelloClass() HelloObject;
HelloObject.saying;
return 0;
}








hello i am relatively new to c++ and lately i have been trying to tackle classes/objects. At line 5 it says i have an error. I have been continually having this problem with any basic class i try to create. If anybody could explain this, i would be greatly appreciative

Classes don't really expect () after their names like you have there. :) That means that lines 5 and 13 need changing.

However, at the same time, member functions do just like any other function. That means line 14 needs changing.

Good luck!

can you post what the code should look like? :)

class ai {
private:
    int row, collumn, returncordiate[2];
    //row, collumn
    char aimap[6][6]; 
    
    
public:
    
    ai(); 
    
    bool check(int i, int j){
        if(aimap[i][j] == 'S') return true;
        else return false; 
    }
    
    int passive1(){
        srand(time(0));
        returncordiate[0] = rand()%7;
        return returncordiate[0]; 
    }
    
    int passive2(){
        srand(time(0));
        returncordiate[1] = rand()%7; 
        return returncordiate[1];
    }
    
};

ai::ai(){
    std::ifstream ship_location;
    ship_location.exceptions(std::ifstream::failbit | std::ifstream::badbit);
    //open file
    try{
        ship_location.open("/Users/home/Desktop/battleship/battleship/ship.txt");
    }
    //catch error
    catch (std::ofstream::failure &e){
        std::cout << "An error has occured";
        ship_location.close(); 
    }
    //upload array
    for(int j = 0; j < 6; j++){
        for(int i = 0; i < 6; i++){
            ship_location >> aimap[j][i]; 
        }
    }
    ship_location.close(); 
}

some code i found on my computer. has a class with a few functions, a constructor, and private/public setup.
this is how you would declare the object.
