14 int main(int argc, char **argv)
15 {
16     char ch;
17     printf("please select operation: r or d: ");
18     scanf("%c", &ch);
19     int tmp = getchar();                                                                
20     if(ch == 'r'){
21         int ren = rename("kolkata.txt", "city.dat");
22         if(0 == ren){
23             puts("Operation of renaming a file is successful.");
24         }else{
25             puts("Operation of renaming a file is failed!");
26         }
27     }   
28         
29     if(ch == 'd'){

31         if(0 == rem){
32             puts("Operation of deletion a file is successful.");
33         }else{
34             puts("Operation of deletion a file is failed!");

人就像是被蒙着眼推磨的驴子，生活就像一条鞭子；当鞭子抽到你背上时，你就只能一直往前走，虽然连你也不知道要走到什么时候为止，便一直这么坚持着。
