fclose写成flose了!
gets有溢出风险,可改成fgets.
改法见注释:
#include
#include
main()
{
FILE *fp;
char str[81],name[10];
gets(name);
if((fp=fopen(name,"w"))==NULL)
{
printf("can not open\n");
exit(0);
}
gets(name); /* 这里改成 fgets(name,sizeof(name),stdin); */
fputs(str,fp);
flose(fp); /* 这里写错了!应该是fclose(fp); */
if((fp=fopen(name,"r"))==NULL)
{
printf("canfhhkjadf\n");
exit(0);
}
fgets(str,strlen(str)+1,fp);
printf("oiehjhsdhfkjdf\n");
puts(str);
fclose(fp);
