Thread: beginner trying to print out a recursive function in main

Hello, I am just practicing some recursion and I am having trouble with printing out a recursive function in main. Here is what I have:

Code:

// This function adds the squares 4, 5 = 4*4 + 5*5 recursiveley
int recursive_sumSquares(int m, int n)
{
    if (m < n)
    {
        return m*m + recursive_SumSquares(m+1, n);
    }

    else
    {
        return m*m;
    }

}

int main()
{
    printf("%d", recursive_sumSquares(4, 7));

    return 0;
}

I am getting an error that says undefined reference to 'recursive_SumSquares'

C is case sensitive. Within the function recursive_sumSquares you call an unknown function recursive_SumSquares.

Isn't it funny how its always the most simplest thing? Ahhhh!! Thank you friend!
