netbeans – make[1]: the directory '/ home / beto / Documents / C ++ / conditional' is exited

I have a question, a few days ago I worked correctly on my C ++ projects of netbeans, but a few moments ago, I get the following:

cd '/ home / beto / Documents / C ++ / conditional'

/ usr / bin / make -f Makefile CONF = Debug

"/ usr / bin / make" -f nbproject / Makefile-Debug.mk QMAKE = SUBPROJECTS = .build-conf
make[1]: you enter the directory '/ home / beto / Documents / C ++ / conditional'

"/ usr / bin / make" -f nbproject / Makefile-Debug.mk dist / Debug / GNU-Linux / conditional

make[2]: you enter the directory '/ home / beto / Documents / C ++ / conditional'

make[2]: 'dist / Debug / GNU-Linux / conditional' is updated.

make[2]: the directory '/ home / beto / Documents / C ++ / conditional' is exited

make[1]: the directory '/ home / beto / Documents / C ++ / conditional' is exited

I also attach the simple code I am using, I have no idea what happened:

#include 

using namespace std;

int main () {

    int number;
    cout <<"Ingrese un número entre [1-12]: ";cin>> number;

    switch (number) {
        case 1: cout << number << "corresponds to the month of January"; break;
        case 2: cout << number << "corresponds to the month of February"; break;
        case 3: cout << number << "corresponds to the month of March"; break;
        case 4: cout << number << "corresponds to the month of April"; break;
        case 5: cout << number << "corresponds to the month of May"; break;
        case 6: cout << number << "corresponds to the month of June"; break;
        case 7: cout << number << "corresponds to the month of July"; break;
        case 8: cout << number << "corresponds to the month of August"; break;
        case 9: cout << number << "corresponds to the month of September"; break;
        case 10: cout << number << "corresponds to the month of October"; break;
        case 11: cout << number << "corresponds to the month of November"; break;
        case 12: cout << number << "corresponds to the month of December"; break;
        default: cout << number << "is not included in the range [1-12]"; break;
    }
    return 0;

}

I do not know if I have to see, that this afternoon we tried a code in which a variable was used too big and I did this when I put it in the main (the code I do not have it, but it was also simple, only declared with # define N 10000 and show it in the main).

It happens to me now with all the projects that I have of C ++

I hope you can help me: 'c
