創(chuàng)建一個(gè)后綴名為txt的文件，并向該文件寫入一個(gè)字符串，保存起來，再打開文件，讀出文件中的內(nèi)容。
代碼如下：
#include<stdio.h>
#include<string.h>
int main()
{
FILE *fp;
char pathName[20],txt1[100]={'\0'},txt2[20]={'\0'};
int fileLen;
printf("Please type the path name of the file\n");
scanf("%s",pathName);
fp=fopen(pathName,"w");
printf("Please input a string to this file\n");
scanf("%s",txt1);
fileLen=strlen(txt1);
fwrite(txt1,fileLen,1,fp);
fclose(fp);
printf("The file has been saved\n");
printf("The content of teh file: %s is\n",pathName);
fp=fopen(pathName,"r");
fread(txt2,fileLen,1,fp);
printf("%s\n",txt2);
return 0;
}
