C语言将日期、时间保存到文本文件中的方法

 FILE *fopen( const char * filename, const char * mode );

 linux文件路径：
 linux：fopen("/tmp/test.txt", "w+");
 
 windows文件路径：
 windows:fopen("E:/Desktop/cyuyan_sz/vs2010/one/jiguoti/temp/a.txt","w+");

int fputc( int c, FILE *fp );

int fgetc( FILE * fp );

char *fgets( char *buf, int n, FILE *fp );

fclose( FILE *fp );

 fprintf(fp,"hello word......\n");
 fputs("hello word......\n",fp);
 fclose(fp);
 getchar();
 return 0;
}

/*
vs2010在编译生成程序之后，dos界面会出现闪退的情况，
解决办法:
1.在源程序后面添加getchar();
2.添加头文件#include之后在main函数结尾前写上system("pause");
