奇怪 怎么分开读取，
#include <stdio.h>#include <string.h>
#define SIZE 15
#define NUM 60
struct ip_net
{
char IP[SIZE];
char NET[SIZE];
}network[NUM];
void main()
{
FILE *fp;
int i;
fp=fopen("d:\\duwenge.txt","r");
for(i=0;i<NUM;i++)
{
fread(&network[i],sizeof(struct ip_net),1,fp);
printf("%s",network[i].IP,network[i].NET); /*为什么一个%s就够了*/
}
fclose(fp);
fp=fopen("d:\\duwenge.txt","r");
int j,index;
index=0;
int k;
for(i=0;i<NUM;i++)
{
for(j=i+1;j<NUM;j++)
{
for(k=0;k<SIZE;k++)
if(network[i].IP[k]==network[j].IP[k]&&network[i].IP[k]!=' '
&&network[j].IP[k]!=' ')
{};/*怎么分开读取*/
break;
}
if(j==NUM)
index++;
}
printf("The number of ip is %d\n",index);
fclose(fp);
}
