Once I programmed a program with turbo c. Every thing is o.k. But today I programmed it with turbo c++,I failed to compile and link. it say"Linker Warning: No module definition file specified:using defaults" "Linker Error: Undefined symbol_main in module WINMAIN" I don't know what error I had made. Can every one here help me?

can you post the code so that we can figure out the problem???

the following is my code #include #include #define NULL 0 #define LEN sizeof(struct student) struct student {long num; float score; struct student *next; }; int n; struct student *creat(void) {struct student *head; struct student *p1,*p2; n=0; p1=p2=(struct student *) malloc(LEN); scanf("%1d,%f",&p1->num,&p1->score); head=NULL; while(p1->num!=0) {n=n+1; if(n==1)head=p1; else p2->next=p1; p2=p1; p1=(struct student *) malloc(LEN); scanf("%1d,%f",&p1->num,&p1->score); } p2->next=NULL; return(head); }

I don't see a 'main()' in your code. That jibes with the error message.
