#include <stdio.h>

#define file_name "test.txt"
int main()
{
int i;
char str[]="hello world!",tmp1[50],tmp2[50];
FILE *fp;
// printf("hello world!\n"); // 一定要练的XD
for(i=1;i<=2;i++)
printf("%d.%s\n",i,str);
printf("please input a word: ");
scanf("%s",tmp1);
printf("the word you inputed is %s.\n",tmp1);
printf("please input another word: ");
scanf("%s",tmp2);
strcat(tmp1,tmp2);
printf("tmp1+tmp2=%s.\n",tmp1);
// 档案处理
if((fp=fopen(file_name,"r"))!=NULL)
{
printf("the file %s is exist.\n",file_name);
while(!feof(fp))
{
if(fscanf(fp,"%s %s",tmp1,tmp2)==2)
printf("%s is a %s\n",tmp2,tmp1);
}
}
fclose(fp);
return 1;
}
===执行结果===
1.hello world!
2.hello world!
please input a word: abc
the word you inputed is abc.
please input another word: def
tmp1+tmp2=abcdef.
the file test.txt is exist.
