用C语言编通讯录程序（初学者级别的）(2) #include <stdio.h>
#include <string.h>
#include <stdlib.h>
#define MAXL 120
typedef strUCt saddr {
char *name;
char *address;
char *zip;
char *phone;
struct saddr *next, *pre;
} ADDR;
char buffer[MAXL], fname[40];
FILE *fp;
int modified = 0;
ADDR *load();
void insert(), make(), find(), del(), display(), show(),
save(), freeall(), usage();
int getstr(FILE*, char **), getbuffer(FILE *);
int main(int argc, char **argv)
{
ADDR *head;
char c;
if (argc == 1) {
printf("请输入通信录文件名. ");
scanf("%s%*c", fname);
}
else{
strcpy(fname, *++argv);
}
head = load(fname);
while (1) {
printf("\n请输入命令: [i, f, d, s, q]\n");
while (getbuffer(stdin) == 0);
if ((c = buffer[0]) == 'q') {
if (modified) {
printf("修改后的通信录未保存，要保存吗?(y/n) ");
while (!(((c = getchar()) >= 'a' && c <= 'z') ¦¦ (c >= 'A' && c <= 'Z')))continue;
if (c == 'y' ¦¦ c == 'Y')
save(head, fname);
}
freeall(head);
break;
}
switch © {
case 'i' :
insert(head);
break;
case 'f' :
find(head);
