I ferito come posso far funzionare questo codice?C++ reference array
#include <iostream>
using namespace std;
void writeTable(int (&tab)[],int x){
for(int i=0;i<x;i++){
cout << "Enter value " << i+1 <<endl;
cin >> tab[i] ;
}
}
int main(void){
int howMany;
cout << "How many elemets" << endl;
cin >> howMany;
int table[howMany];
int (&ref)[howMany]=table;
writeTable(ref,howMany);
return 0;
}
e qui ci sono gli errori che ho:
|4|error: parameter ‘tab’ includes reference to array of unknown bound ‘int []’|
|18|error: invalid initialization of reference of type ‘int (&)[]’ from expression of type ‘int [(((unsigned int)(((int)howMany) + -0x00000000000000001)) + 1)]’|
|4|error: in passing argument 1 of ‘void writeTable(int (&)[], int)’|
Grazie per l'aiuto
C++ non ha VLA. – kennytm
Potresti usare std :: vector –
