Arrays (Unlimited Input)

[Ella99991]

What I am trying to do, is allow the user to input any number of variables (for ex: 1 6 945 fhds)and my program will check for any strings. I have heard of arrays, but I feel like I can only limit how many inputs the user can have. Foo seems to need pre-input coded into the program? Can anybody clarify how to do this?

I tried lol:

#include <iostream>
using namespace std;

int main() {
int x;
int array[x];
cout << "Enter 5 numbers: ";
for (int x = 0; x = <char>; ++x) {
cin >> x;
}
cout << x;
return 0;
}

Arrays cannot be resized - once they are created they are stuck with that size forever.

You want to use a dynamically resizing container like std::vector - it will resize itself for you:

#include <iostream>
#include <vector>

int main()
{
    std::vector<int> numbers;
    int temp;
    while((std::cout << "Enter a number: ") && (std::cin >> temp))
    {
        numbers.push_back(temp); //numbers will resize itself automatically
    }
    //...
}
