write a c program to calculate the dicrete derivative using this information

Q5 Calculations Assume x1, x2, x3, x4 are four measurements collected at 1ms time intervals. Calculate the discrete derivative using this equation d = x1+3*x2-3*x3-4 If the units of x1 is mV, then the units of d will be mV/ms (or V/s). Assume the inputs are 16-bit signed numbers ranging from 0 to 3300. Solve overflow by limiting the output to - 1000 to +1000 V/s. Hint, calculate the intermediate result in 32-bit math, check for overflow, and then return a 16-bit result. The prototype for this function is int16_t Derivative (int16 t xi, int16_t x2, int16_t x3, int16_t x4)
