include <stdio.h>
#include <string.h>
int main(void)
{
    FILE *ap,*bp;
    char name[10],ch[40];
    gets(name);
    ap = fopen(name,"r");
    bp = fopen("xx.txt","a+");
    while(fgets(ch,40,ap) != NULL)
    {
        printf("读取文件成功\n");
        if((strcmp(ch,"163")) == 0)
        {
            printf("比较成功\n");
            fputs(ch,bp);
        }
        else
            printf("比较失败\n");
    }
    fclose(ap);
    fclose(bp);
    return 0;
}

这里我想把文件一行一行的读入数组,再比较数组中是否有163如果有就把它写入另一个文件,
为什么比较不出来呢?
