good evening all, im in the process of writing a code that will calculate loan payments. I made the equation for the interest formula, but when I compile it, I get the error:

"called object is not a function"

I tried to simplify the equation as much as I could, and from what i can tell it should be right. Anyone see something I missed? Thanks in advance.Code:void calc_loan(char*loan_amount, char*apr, char*loan_term, float *payment) { float i = (*apr/12); float x = (1+i); *payment = *loan_amount(i ((pow((x), *loan_term)))/((pow((x), *loan_term) -1))); }
