我的任务
分享老大,急!!!从文件读取??
我想请问一下,如果从文件中读取数据,
例如文件::
123 45678
如何把123读入第一个数组中,跳过空格后,把45678读入第二个数组中?

用fstream也行呀,不过楼主,以后问问题不用这么小气,多给点分,这个分来的也快,不用这么节省的

用sscanf（）
Example
/* SSCANF.C: This program uses sscanf to read data items
* from a string named tokenstring, then displays them.
*/
#include <stdio.h>
void main( void )
{
char tokenstring[] = "15 12 14...";
char s[81];
char c;
int i;
float fp;
/* Input various data from tokenstring: */
sscanf( tokenstring, "%s", s );
sscanf( tokenstring, "%c", &c );
sscanf( tokenstring, "%d", &i );
sscanf( tokenstring, "%f", &fp );
/* Output the data read */
printf( "String = %s\n", s );
printf( "Character = %c\n", c );
printf( "Integer: = %d\n", i );
printf( "Real: = %f\n", fp );
}
Output
String = 15
Character = 1
Integer: = 15
Real: = 15.000000
