the book im learning from told me to write this code but when i do i get
error: 'endl' was not declared in this scope. on line 9

#include <iostream>
int main()
{
    int x = 0;
    int i;
    for (i = 1; i <= 100; i++) {
    x += i;
    }
    cout << x << endl;
    return 0;
}

type this between main function and #include <iostream>:

using std::cout;
using std::endl;

[Gregory Sakas]

Type using namespace std; in between main function and #include <iostream>. It automatically includes cout, cin, endl, etc.
