Thread: Initialize for loop using input from keyboard?

I'm not finished with this code, but I am stuck on this one glitch. This is what I have so far, and it's not working. Please let me know if you have any ideas on how to make this work.

Code:

int main()
{
    /*Please input an n value greater than zero. Otherwise, exit the program by entering a carriage return*/
    printf("Please input an n value greater than zero. Otherwise, exit the program by entering a carriage return\n\n");
    int summation = 0, x, y;
    scanf("%d", y);
    
    
        for (y == x; summation <= M_E && x <= 34; x++)
        {
            summation = 1 / x;
            summation += summation;
        }


        printf("%12f\n\n", summation);
        system("pause");
        printf("Enter in a new n value to compute\n\n")


}

Thanks in advance
