Help in combining two functions in c++

Question

I am just trying something with somebody else\'s code.

I have two functions:

int Triangle(Render *render, int numParts, Token *nameList, Pointer *valueLi         


        

Answer 1

I strongly recommend you to go with Functions because it allows better separation of logic and allows you to reuse the logic. But still in case if you want to use it that way please check the function below :

 int Triangle(Render *render, int numParts, Token *nameList, Pointer *valueList) 
        {
            int iOuter;
            for (iOuter=0; iOuter(*pv[j])[1] || 
                                                (*pv[i])[1]==(*pv[j])[1] && (*pv[i])[0]>(*pv[j])[0]) {
                                                Coord *tmp;
                                                tmp = pv[i];
                                                pv[i] = pv[j];
                                                pv[j] = tmp;
                                        }
                                }
                            ;

                            // all y the same?
                            if ((*pv[0])[1] == (*pv[2])[1]) {
                                drawHorizonLine(render, *pv[0], *pv[2]);
                                return SUCCESS;  
                            }

                            // assign middle point
                            Coord mid; 
                            mid[1] = (*pv[1])[1];       // y
                            float ratio = ((*pv[1])[1] - (*pv[0])[1]) / ((*pv[2])[1] - (*pv[0])[1]);
                            mid[0] = (*pv[0])[0] + ratio * ((*pv[2])[0] - (*pv[0])[0]); // x
                            mid[2] = (*pv[0])[2] + ratio * ((*pv[2])[2] - (*pv[0])[2]); // z

                            if (mid[0]<=(*pv[1])[0]) {  // compare X
                                drawTrapzoid(render, *pv[0], mid, *pv[0], *pv[1]); // upper tri
                                drawTrapzoid(render, mid, *pv[2], *pv[1], *pv[2]); // lower tri
                            }else{
                                drawTrapzoid(render, *pv[0], *pv[1], *pv[0], mid); // upper tri
                                drawTrapzoid(render, *pv[1], *pv[2], mid, *pv[2]); // lower tri
                            }

                            return SUCCESS;

                        }

                        break;
                }
            }

            return SUCCESS;
        }
