OA) int positive ( double xi 1. int npts) ( int npos 0; for (int k =0;k 0) npos++) return npos; ) OB) int positive ( double xI1, int npts) ( int npos 0; fondmo.kts k if (xk> 0) npos+ return npos; ) OC) int positive ( double xI 1. int npts) {int rpo s = 0; for (int k 0; k 0) npos++:) return npos; ) OD) int positive ( double x( 1. int npts) int npos 0; for (int k 0; k 0) npos++ ) etum npts;) 29.
