fwrite、fprintf、fputc等写文件函数都可以完成,而专用的字符串文件写入函数fputs更方便一些。举例如下(文件建立在当前目录下,名为123.txt):
//#include "stdafx.h"//If the vc++6.0, with this line.
#include "stdio.h"
#include "string.h"
#include "stdlib.h"
int main(void){
char s[70];
FILE *fp;
if((fp=fopen("123.txt","w"))==NULL){
printf("Open the file failure...\n");
exit(0);
}
while(1){
printf("Input a string...\ns=");
if(gets(s),strlen(s)<70)
break;
printf("Too long, redo: ");
}
fputs(s,fp);
fclose(fp);
printf("\n");
return 0;
