CREATE TABLE IF NOT EXISTS STUDENT(Sno integer primary key, Sname text not null, Ssex text,Sage integer check(Sage>14),Sdept text default 'CS'); 该表的属性就是按照上一节表属性 执行结果: 查看表: 看到STUDENT,说明该表创建好了。【注意】
The ntohs() function converts the unsigned short integer netshort from network byte order to host byte order. On the i386 the host byte order is Least Significant Byte first, whereas the network byte order, as used on the Internet, is Most Significant Byte first. // ENDIANNESS 端序 自测 ...

在文件处理中,通过putc()函数 ,我们将来自stdin的字符写入输入文件流,并递增文件位置指针。 函数putc()的原型是int putc(const char * string,FILE * filename); It returns an integer value which is conversion of an unsigned char. It also returns EOF, if an error occurs. Whenever there is a binar...

of allocation to build buffers as a builder stack provides an extensible arena before committing objects - for example appending strings or vectors piecemeal. The stack is mostly bypassed when a complete object can be constructed directly such as a vector from integer array on little endian ...
printf("This is a test string.%n",len); 字符串读取,当缓冲区小于所要读入的字符串长度时(此类的函数包括scanf、fscanf、sscanf、gets、getc、fgets、fgetc等)。 // 用户输入的字串长度不受控制,如果超过10,就会造成缓冲区溢出。charbuf[10];scanf("%s", &buf); ...
tperrordetail() returns an integer which is then used as an argument to tpstrerrordetail() to retrieve a pointer to a string that contains the error message. The pointer can then be used as an argument to userlog or to fprintf()....
