For string, no superfluous

reference 1/f, Simple, Soft reply:

for strings, no redundant

Can explain why the input letters slightly subclass is not all because of a carriage return character in the reason?

CodePudding user response:

Why do you want to * s? Character % s is a string,
Because you are integer variables, so you will get a small number of omission,
If you want to define other input with a decimal, such as double types, input use % lf good!
% % s is a character type c, you lose in also not ah, losing a digital implicit conversion may not succeed, this I haven't written so, not too clear, but you lose the letters to digital variables, will certainly be a problem, not just a single character

MSDN mentioned
An asterisk (*) following the percent sign suppresses the assignment of the next input field, which is interpreted as a field of the specified type. The field is scanned but not stored.
Mean, roughly the scanf () function parameters, add an asterisk behind percent *, said an asterisk after all the parameters are invalid, the use of an asterisk is to read the contents of the stream, but does not store the content,
