#include
main()
{
FILE *fp;
int i;
fp=fopen("wenjian", "rb");
if(fp==NULL)
puts("File open error");
i=fclose(fp);
if(i==0)
printf("O,K");
else
puts("File close error");
}
2.运行后产生一个text.dat的文件
#include
main()
{
char *s="That's good news");
int i=617;
FILE *fp;
fp=fopne("test.dat", "w");
fputs("Your score of TOEFLis", fp);
fputc(':', fp);
fprintf(fp, "%d\n", i);
fprintf(fp, "%s", s);
fclose(fp);
}
