c++ - 为什么这段C代码执行之后结果为1245？

Answer 1

First, 1, 2, 3 are the values ​​of c1, c2, and c3 respectively, then enter is the value of c4, and then 4, 5 are the values ​​​​of c5, c6, so the output is 1, 2, 4, 5

You can output c4 in integer format and find that it corresponds to ASCII 10

Don’t write code like this. .

Answer 2

Scanf input characters will read carriage returns, spaces, and tabs, but input strings will be ignored.
