error C2660: 'pow' : function does not take 1 parameters

[denxx]

Hi, I am new in C++ and was trying to run a programme where I found an error using the pow statement. Error showed is error C2660: 'pow' : function does not take 1 parameters. As I have a square on the whole equation, I am not sure whether I am sure the power function right.

Please advise, anyone?

Code shown as below:

eqn=vf[j]+((vf[j]*(1-x)+vg[j])*x);
fun3 = 1000*hf[j]+1000*hfg[j]*x+(m*m*(pow(eqn,2.0))/2-1000*h[i]-(pow(V[i],2.0)/2));

many thanks!

Whatever error you are getting is not in this code. This compiles OK:

double eqn;
    double vf[100];
    double vg[100];
    double hf[100];
    double hfg[100];
    double m;
    double x;
    int i;
    double V[100];
    double fun3;
    int j;
    double h[100];
    eqn=vf[j]+((vf[j]*(1-x)+vg[j])*x);
fun3 = 1000*hf[j]+1000*hfg[j]*x+(m*m*(pow(eqn,2.0))/2-1000*h[i]-(pow(V[i],2.0)/2));
