help with netcode!

hey guys, my netcode for this game is extremely terrible, can someone help me improve it? my code is very messy and complicated, sorry.. =[ but any suggestions would be very appriciated!

Code:

SDL_Flip(pSurface); char addy; ifstream getconfig("config.txt"); int cliserv; getconfig>>cliserv; if(cliserv == 0) servmain(pSurface); else { // getconfig.getline(&addy,15,'\n'); char decoy = 'z'; climain(pSurface, decoy);
