上面是一个文件夹里的文件，windows.txt
现在我想把第1   6    11   16  行的数读出来。即2   5   7  9读出来。要怎么做。请大家看看。

在scanf中用*过滤掉啊

不太懂。麻烦再指点下

用fgets读，然后搞个计数的变量，遇到你希望读的行，拿出来用就是了。

#include <stdio.h>

#define MAXSIZE 100
int main()
{
    char str[MAXSIZE];
    int n = 0;
    int cnt = 0;
    FILE *fp = NULL;

    if((fp = fopen("F:\\test.txt","r")) == NULL)
    {
        printf("can't open file!\n");
        exit(-1);
    }

    while(fgets(str, 100, fp) != NULL)
    {
        ++cnt;
        if(cnt == 1 ||cnt == 6 ||cnt == 11 ||cnt == 16)
        {
            sscanf(str, "%d", &n);
            printf("cnt = %d, n = %d\n", cnt,n);
        }

    }
    return 0;
}
提供参考。

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#define MAXIN 1024

int main()
{
    char readout[MAXIN] , store[100][100];
    int count = 0 , n = 0;
    FILE *p_file;
    p_file = fopen("windows.txt" , "r");
    while(fgets(readout,MAXIN,p_file))
    {
        if(!count)
            strcpy(store[n++] , readout);
        count++;
        if (count == 5)
            count = 0;
    }
    for (count = 0;count < n ;count ++)
        printf("%s",store[count]);
    fclose(p_file);
    system("pause");
    return 0;
}

谢谢楼上几位
