1 AnswerProgramming & Design10 years agoinitilize c++ user values in an array?
I'm trying to import 10 numbers into an array that the user would enter. I'm using a for loop shown below.
void Array::initilize()
{
for (int i=0; i<9; i++)
{
cout << "enter a value for the 10 spaces in the array :" <<endl;
cin >> array[i] >> endl;
}
}
for some reason its not liking the line cin >> array[i] >> endl;
how should i go about getting user data for my array ( should i not be using a for loop?)
