for(i = 0; i < cant; i++){

printf("\ninsert: ");
cin>>num[i];

printf("\n(1) ver num\n(2) modificar num");

printf("\n\noption: ");
cin >> op;
cout<<endl;

switch(op){
case 1:

for(i = 0; i < cant; i++)
cout <<"num: "<< num[i];
break;

case 2:

cout <<"num: "<< num[i] << endl;

}

printf("\nModificar: ");
