I'm having some problems with fuctions could someone please get me going in the right direction. thanks

Code:#include <iostream> #include <iomanip> #include <cmath> using namespace std; const int row=12, col=18; void windchill (double temp[][windspeed]); void print_wind (double n[][col]); int main() { double temp, windspeed; windchill (temp); print_wind (windchill); return 0; } void windchill (double temp[],[windspeed]) { double t, v, chill; for ( t = 40;t <= -45;t -= 5 ) for ( v = 5; v <= 60; v += 5) { chill = 35.74+0.6215(t)-35.75(v ^ 0.16)+0.4275(t)(v^0.16) } } void print_wind (double n[][col]) { int i,j,t,v; cout << "\t\t Wind Speed in MPH / Temperture in F \n\n"; for (i=0,t=40;i<col;i++,t-=5); cout << setw(4) << t; cout << "\n\n"; for (i=0,v=5;i<row;j++,v+=5); { cout << setw(2) << v; for (j=0;j<col;j++) cout << setw(4) << n[i][j]; cout << "\n"; } }
