# include <stdio.h>

int main()
{
    char ch[20], ch2[20];
    int i;
    int len;

    gets(ch);
    len = strlen(ch);
    for(i=0; i<5; i++)
        ch2[i] = ch[i];
    for (i=6; i<len; i++)
        ch2[i-1] = ch[i];
    for (i=0; i<len-1; i++)
        printf("%c\n", ch2[i]);    //1行

    printf("%s\n", ch2);                //2行
    
    return 0;
}

在VC++6.0的结果：
