我要考三级 网络技术，得机试C语言 试题目难度如下  请问我还需要学 谭浩强的C程序设计那几章？我已经学了1-6章了 #include <conio.h>
#include <stdio.h>
void readwriteDat();
void num(int m, int k, int xx[])
{
    int  data = m+1;
    int  half, n = 0, i;
    while(1)
    {
        half = data/2;
        for (i=2; i<=half; i++)
            if (data%i == 0)
                break;
        if (i > half)
        {
            xx[n] = data;
            n++;
        }
        if (n >= k)
            break;
        data++;
    }
}
main()
{
    int  m, n, xx[1000];
    printf("\nPlease enter two integers:");
    scanf("%d%d", &m, &n);
    num(m, n, xx);
    for (m=0; m<n; m++)
        printf("%d ", xx[m]);
    printf("\n");
    readwriteDat();
}
void readwriteDat()
{
    int  m, n, xx[1000], i;
    FILE  *rf, *wf;
    rf = fopen("in.dat", "r");
    wf = fopen("out.dat", "w");
    for (i=0; i<10; i++)
    {
        fscanf(rf, "%d %d", &m, &n);
        num(m, n, xx);
        for (m=0; m<n; m++)
            fprintf(wf, "%d ", xx[m]);
        fprintf(wf, "\n");
    }
    fclose(rf);
    fclose(wf);
}

还有函数，数组，指针吧！
