c++ - a是多个字符和空格时，fscanf (fp,"%d",&a)调用之后，fp指针位置跳过空格吗？

问题描述

比如

fp内容:'how are you';

fscanf (fp,'%d',&a);fscanf (fp,'%d',&b);

a输出howb输出are吗？为什么第二次调用fscanf自动跳过空格？

问题解答

Whitespace character: the function will read and ignore any whitespace characters encountered before the next non-whitespace character (whitespace characters include spaces, newline and tab characters -- see isspace). A single whitespace in the format string validates any quantity of whitespace characters extracted from the stream (including none).http://www.cplusplus.com/refe...
