ARRAY PROBLEM

[pachanga1992]

int main(){ 

int card[],number; //MY Question is about this line .

cout<<"Number =";
cin>>number;

for(int a=1;a<=number;a++){ 
card[a]=a; 
cout<<card[a]<<endl;} 

return 0; 
}

I dont know the size of card[] array because user decides it .
what should ı do ?
I need the answer for an other code . So ı cant write "int card[number]" under the cin line.

Use a vector:

#include <vector> 
std::vector<int> card; 
for(a=0; a<number; a++)
{  card.push_back (a);
    cout<<card[a]<<endl;
}
