请各位看一下 实在没辙了

没有相应的数据类型，建议你用typedef关键字替换掉早不到的数据类型

status initlist_sq(sqlist *L) 这几个函数定义的时候不要用status 用int,一共有3个这样顶一的函数，返回值全换成int

m!="ok") 这里不应该加双引号

if(k=="stop") break; 哪个老师教你这样写的？ k是个字符不是字符串，能跟字符串比较吗？ 另外字符串也不是用==比较的，用strcmp啊。，你那里居然能编译过去？

自己先改一下，一会给你发出正确代码来

#include "stdio.h" #include "stdlib.h" #include <string.h> #define list_init_size 100 #define listincreament 10 #define ElemType char enum status{ok,fail}; typedef struct{ ElemType *elem; int length; int listsize; }sqlist; enum status initlist_sq(sqlist *L) { (*L).elem=(ElemType*)malloc(list_init_size*sizeof(ElemType)); if(!L->elem) return fail; else { L->length=0; L->listsize=list_init_size; return(ok); } } enum status listinsert_sq(sqlist *L,int i,ElemType e) { char *newbase; char *p,*q; if(i<1||i>L->length+1) return fail; else { if(L->length>=L->listsize) { newbase=(ElemType*)realloc(L->elem,(L->listsize+listincreament)*sizeof(ElemType)); if(!newbase) {return fail;exit(1);} L->elem=newbase; L->listsize+=listincreament; } q=&L->elem[i-1]; for(p=&L->elem[L->length-1];p>=q;--p) *(p+1)=*p; *q=e; ++L->length; return (ok); } } enum status listdelete_sq(sqlist *L,int i,ElemType *e) { char *p,*q; if(i<1||i>(*L).length) return fail; else { p=&L->elem[i-1]; q=&L->elem[L->length-1]; e=p; for(++p;p<=q;++p) *(p-1)=*p; --L->length; return ok; } }

void main() { sqlist *L;char e,k,stop[10]={0};int i; enum status m; L=new sqlist; m=initlist_sq(L); if(m!=ok) { printf("not successfull\n"); getchar(); exit(0); } i=1; while(1) { printf("please input the dataes:\n"); scanf("%s",&e); getchar(); m=listinsert_sq(L,i,e); i++; if(m==fail){printf("not successfull\n");return;} printf("please input stop or continue\n"); scanf("%s",stop); getchar(); if(strcmp(stop,"stop")==0) break;

程序里面有逻辑错误，只是可以运行了，具体那里少做了什么处理你自己试着找一找吧

编译错误都给你耐着性子揪出来了，不过在查错的同时发现你这个代码的逻辑有很大问题，很多地方甚至是一些没有道理的错误。代码给你贴出来，不过要在你这个代码的基础上改正确真是一大挑战，我劝你还是重写一个好了。。。 #include "stdio.h" #define list_init_size 100 #define listincreament 10 #define ElemType int enum status{ok,fail}; typedef struct{ ElemType *elem; int length; int listsize; }sqlist; status initlist_sq(sqlist *&L) { (*L).elem=(ElemType*)malloc(list_init_size*sizeof(ElemType)); if(!L->elem) {return fail; exit(0);} L->length=0; L->listsize=list_init_size; return(ok); } status listinsert_sq(sqlist *L,int i,ElemType e) { sqlist *newbase; int *p,*q; if(i<1||i>L->length+1) {return fail;exit(1);} if(L->length>=L->listsize) { newbase=(sqlist*)realloc(L->elem, (L->listsize+listincreament)*sizeof(ElemType)); if(!newbase) {exit(1);return fail;} L=newbase; L->listsize+=listincreament; } q=&L->elem[i-1]; for(p=&L->elem[L->length-1];p>=q;--p) *(p+1)=*p; *q=e; ++L->length; return ok; } status listdelete_sq(sqlist *L,int i,ElemType *e) { int *p,*q; if(i<1||i>(*L).length) {return fail;exit(2);} p=&L->elem[i-1]; q=&L->elem[L->length-1]; e=p; for(++p;p<=q;++p) *(p-1)=*p; --L->length; return ok; } void main() { sqlist *L;char e,c; char k[100];int i,u;enum status m; m=initlist_sq(L); if(m!=ok) { printf("not successfull\n"); getchar(); exit(1); } printf("please input the dataes:\n"); i=1; while(1) { scanf("%s",&e); getchar(); m=listinsert_sq(L,i,e); i++; if(m==fail){printf("not successfull\n");exit(1);} printf("please input stop or continue\n"); scanf("%s",&k); getchar(); if(strcmp(k,"stop")==0) break; } printf("you want insert the data y or n ?\n"); scanf("%c",&c); if(c=='y') while(1) { printf("data:e="); scanf("%d",&u); printf("\n"); printf("location:i="); scanf("%d",&i); printf("\n"); m=listinsert_sq(L,i,u); if(m!=ok){printf("not successful\n");goto loop1;} printf(" is successfull\n"); printf("you want to continue insert other data y or n?\n"); scanf("%c",&c); if(c!='y') break; } loop1:printf(" you want to delete the data y or n?\n"); scanf("%c",&c); if(c=='y') loop2: while(1) { printf("i="); scanf("%d",&i); m=listdelete_sq(L,i,&u); if(m!=ok){printf("not successful\n");goto loop2;} printf("%c",e); printf("is deleted\n"); printf("you want to continue todelete other data y or n?\n"); scanf("%c",&c); if(c!='y') break; } printf("over\n"); }
