Need help with segmentation fault

[Micaela]

Hi everybody!
I'm a real beginner in programming, because I started classes one month ago at the university; I've got a problem with a really simple exercise with an array, i wrote this program on emacs:

 #include <iostream>
using namespace std;

int main() {
int dim;
double x[i];

cout<<"Give me the number of elements of the array" <<endl;
cin>>dim;
<<"Give me the " <<dim <<"elements of the array" <<endl;
for(int i=0;i<dim;i++) {
cin>>x[i];
}
cout <<"The elements of the array are" <<endl;
for (int i=0; i<dim; i++) {
cout <<x[i] <<", ";
}
cout <<endl;
}

till 4 elements the programm works, but when I put dim=5 it gives me "segmentation fault"

That code shouldn't even compile. In line 6, i is undeclared and on line 10, you're missing a cout.

You need to use dynamic allocation if you want the size of your array to be set at runtime (or preferably use vectors, but I don't know if your class is covering them).

Good luck!

Thank u for the tip..I forgot the dynamic allocation..a real shame >.<
