float total = (sqrt(
          ((point_A[j].length)*(point_A[j].length))+
          ((point_B[j].width)*(point_B[j].width))+
          ((point_C[j].height)*(point_C[j].height))
                                                        ));

Is it possible to optimize this code to reduce number of instructions performing on it? 
int32 find_result(int64 sec)
{

    if(config == defualt_base)
    {
        uint32 H      = j * k + 1; /*(here j and k global)*/

        if((((uint32)(sec - CS - RS)) % (H * N_p * M_r))== 0) 
        {
            result = 0;
        }
    }
    else
    {
        if((((uint32)(sec - CS - RS)) % (N_p * M_r))== 0)  /*(N_p and M_r global)*/
        {
            result = 0;
        }
    }
}

This function have to be execute several times in a second, How can optimize it ? Please help me to avoid mathematical operations applying on this function?

How to calculate wind chill index for the given temprature and wind speed.

The wind chill index (WCI) is calculated from the wind speed (v) in miles per hour and the temprature (t) in
fahrenheit . three formulas are used . depending on the wind speed :
if(0<=v<=4)then WCI=t
if(v>=45) then WcI =1.6t-55
otherwise , WCI=91.4 + (0.0203v - 0.304(v)^1/2 - 0.474)

write a program that prompt the user to insert the wind speed (v) in miles per hour format and prompt the user to insert wind temprature on fehrenhite then calculate the wind chill index
