My school is the shitty kinda school,so asking for help here is kinda outta the option list,i can work with stdio.h,conio.h,string.h,a little with fcntl.h and io.h,i think thats all there is to know about my programming and btw i barely work with void cause i dont get what does it exactly do to help

ps: ty for the link xpi0t0s i think i got an idea from that,but if any1 has more sugestions il be more than glad to listen
