如果我希望对象在回发中保持不变,那么在ViewState中存储Object是个好主意吗？还有更好的想法吗？我担心ViewState的大小太大了......

   typedef struct {
      void *elems;//address of the memory block
      int elemSize; //
      int logicLen;//number of existing elements in vector
      int allocLen;//allocated space for the vector
  } vector;

  static void InsertNumbers(vector *numbers, long n, long d)
  {
    long k;
    long residue;

    for (k = 0; k < d; k++) {
      residue = (long) (((long long)k * (long long) n) % d);
      VectorAppend(numbers, &residue);
    }
  }



void VectorAppend(vector *v, const void *elemAddr)
{
   void *target=(char*)v->elems + (v->logicLen * v->elemSize);

   if(v->logicLen==v->allocLen){
    v->allocLen*=2;
    v->elems=realloc(v->elems,v->allocLen*v->elemSize); …

执行main,它会要求输入.

将输入存储在argbuf中.

然后,使用strwrd将argbuf拆分为标记

然而,它说"错误:将char*分配给char [200]的不兼容类型"

我无法弄清楚为什么..

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
char argbuf[200];//used to store input

char *strwrd(char *s, char *buf, size_t len, char *delim){
    s += strcspn(s, delim);
    int n = strcspn(s, delim); /* count the span (spn) of bytes in */
    if (len-1 < n)             /* the complement (c) of *delim */
        n = len-1;
    memcpy(buf, s, n);
    buf[n] = 0;
    s += n;
    return (*s == 0) ? NULL : s;
}



int main(){
    fgets(argbuf, sizeof(argbuf), …
