int list_menu314(){
    char str[100];
    char *p,a;
    printf("Please type in your string:\n");
    getchar();
    gets(str);
    printf("\nType the character looking for in \"%s\"\n",str);
    scanf("%s",&a);
    p=strchr(str,a);
    while(p!=NULL){
                   printf("This character can be found at %d\n",p-str+1);
                   p=strchr(p+1,a);
                   }
                  
    getch();
    }

这个程序那边错了 我单独拿出来运行就可以 但是放到我的 主程序里面当fun时 就有问题了

Please type in your string这句 都没让我停顿。。。直接跳到下面了  请求大虾 帮助

scanf("%s",&a);字符型输入，你把程序贴上来看看

这是我的 main fun
上面那个 是我的 fun   麻烦帮我看下了 谢谢

#include<stdio.h>

main(){
     void list_menu1(),list_menu11(),list_menu22(),list_menu33();
     int list_menu111(),list_menu112(),list_menu113(),list_menu114(),list_menu211(),list_menu212(),list_menu214(),list_menu215();
     int sizeofarray,list_menu213(),list_menu216(),list_menu311(),list_menu312(),list_menu313(),list_menu314();
     int l,m;
      
      
     do {
     list_menu1();
     scanf("%d",&l);
     switch(l){
               case 1: list_menu11();
                      scanf("%d",&m);
                       switch(m){
                                 case 1: list_menu111();
                                 case 2: list_menu112();
                                 case 3: list_menu113();
                                 case 4: list_menu114();
                                 break;
                                 }
               case 2: list_menu22();
                       scanf("%d",&m);                          
                       switch(m){
                                 case 1: list_menu211();
                                 case 2: list_menu212();
                                         getch();
                                 case 3: list_menu213();
                                         getch();                              
                                 case 4: list_menu214();
                                 case 5: list_menu215();
                                 case 6: list_menu216();
                                break;
                                }
               case 3: list_menu33();
                       scanf("%d",&m);
                       switch(m){
                                 case 1: list_menu311();
                                 case 2: list_menu312();
                                 case 3: list_menu313();
                                 case 4: list_menu314();
                                 break;
                                 }
               break;                 
               }
                           
         }while(l!=4);
     }

那个程序和主函数也没什么联系，单独来说是对的，可能是其他方面的原因吧、
Please type in your string这句 都没让我停顿。。。直接跳到下面了  请求大虾 帮助  
怎么会不对呢？这里 没什么问题

哦 我同学 帮我加了 getchar（）不好意思  能不能帮我再看下这个

能运行 但是 我add 的string 会少掉一位 这是怎么回事啊

就像我的截图 在附件

int list_menu311(){
     int i,m=0,n=0;
      char j,a[100],b[100];
      
      printf("Please enter your string:");
      getchar();
      gets(a);
      printf("Please enter the word you want to add:");
      getchar();
      gets(b);
      while(a[m]!='\0')
      m++;
      while(b[n]!='\0')
      n++;
      printf("Where you want to add the words?(f/r)");
      scanf("%c",&j);
      if(j=='f'){
      for(i=0;i<m;i++)
      printf("%c",a[i]);
      printf(" ");
      for(i=0;i<n;i++)
      printf("%c",b[i]);
      }
      else if(j=='r'){
      for(i=0;i<n;i++)
      printf("%c",b[i]);
      printf(" ");
      for(i=0;i<m;i++)
      printf("%c",a[i]);}
      else{
      printf("You only can add the words on front or rear!");
      }
      getch();
      return 0;
    }

getchar();
      gets(a);
不要加getchar();它吃掉你第一个输入的字符；

但是我不加 就会出现 这个问题 我无法输入  这个问题Please enter your string 的答案
如附件   第一个问题 和 第二个问题 直接连在一起了

Please the number  不知道你说哪了，在函数开头加了fflush(stdin);清除缓冲区。看看

还是不行，，，，

你整个文件多大？传上来？，
