Dear All,

I wrote two simple functions one of which works (sum) and the other (deduct) gives same values for all vector elements. Where did I go wrong???

Thank you

Code:vector <double> deduct (const vector<double>& v, double k) { vector<double> d(v.size()); for(int i=0; i < v.size();++i) d[i]=v[i]-k; return d; } double sum (const vector<double>& v) { double c=0.000000000; for(int i=0; i < v.size();++i) c +=v[i]; return c; } #include <vector> main() { vector <double> vect(8); double fidy []={112.999,112.994,112.994,-0.005,-0.007,-13.004, -113.003,-113.005}; vector<double> yfid(fidy,fidy+imarknum); double k=sum (vect); v=deduct (vect, k); }
