缺少函数标头C ++

Question

i am getting this error when i want to build my cpp file.

Severity Code Description Project File Line Suppression State Error C2447 '{': missing function header (old-style formal list?) Win32Project1 d:\\persoonlijk\\documenten\\2e leerjaar\\c++\\win32project1\\win32project1\\leerlinggegevens_hfst3.cpp 2

Here is the code i am using:

/*Hoofdstuk 3, Leerlinggegevens*/
#include <iostream>
#include <string>
using namespace std;
int main()
{
    int lnr;
    string lnm;
    string oplnm;
    string klasm;
    //DECRALEREN

    cout << "Voer je leerlingnummer in: \n";
    cin >> lnr;


    cout << "Vul je naam in: \n";
    cin >> lnm;

    cout << "Vul je opleiding in: \n";
    cin >> oplnm;

    cout << "Vul je klas in: \n";
    cin >> klasm;

    cout << "Jouw ingevulde leerleerlinggegevens bestaan uit: \n" << "Leerling " << lnr << " met leerlingnummer " << lnm << "staat ingeschreven bij opleiding " << oplnm << " \n" << "Leerlingnummer " << lnr << " zit in klas " << klasm << endl;


    system("PAUSE");

}

Thanks for your time!

Answer 1

Your code works fine in Windows environment it seems.

In case you are running on Linux environment, but I am not quite sure whether system("PAUSE"); works over there or not. Even, this seems to me as non - portable code.

I would recommend you to use cin.get() or getchar() instead, to make it portable. If you want to more why I am saying so, you can go through this link: http://www.gidnetwork.com/b-61.html

Answer 2

The source code you posted compiles just fine with both Microsoft Visual C++ 2015 and gcc (tried on ideone.com).

The only way to get the C2447 compile error you are getting, with Visual C++, is to add a semi-colon (;) right after main():

int main();
{

(but Visual Studio 2015 editor highlights the error, even before compiling the code).
