}
void listall(void)
{
int i=0;
if(head==NULL){printf( "\nempty list.\n ");return;}
thisnode=head;
do{
printf( "\nrecord number:%d\n ",++i);
printf( "student name:%s\n ",thisnode-> studname);
printf{ "student number:%ld\n ",thisnode-> studnum};
printf( "student age:%d\n ",thisnode-> studage);
printf( "student sex:%c\n ",thisnode-> studsex);
printf( "student score:%6.2f\n ",thisnode-> studscore);
thisnode=thisnode-> nextnode;
}while(thisnode!=NULL);
}
程序有点长，辛苦各位了。
问题这样，在用turbo c 2.0编译该程序时，提示说“void appendnewnode(void);”这条语句在定义中有太多的类型，十分不解。
[解决办法]
struct studtype
{
char studname[20];
long studnum;
int studage;
char studsex;
float studscore;
struct studtype *nextnode;
}; ------------> 分号忘记写了.
[解决办法]
后面一个getchar()是用来接收你输入字符之后的回车的
如果不加， gets(thisnode-> studname);这个语句会接收回车，thisnode-> studname这个就为空了
