qui è il mio programma CPPC++ di base colpa programma di segmentazione
#include <iostream>
int main(int argc, char *argv[]){
return 0;
}
la compilazione e l'esecuzione di questa, provoca un errore seg:
[18:08 ~] > g++ test.cpp
[18:09 ~] > ./a.out
Segmentation fault
Qualcuno ha un'idea su questo problema per favore? Grazie mille per il vostro aiuto.
Qui ci sono alcuni dettagli che potrebbero essere utili:
