Small white sincerely ask, just didn't take long to learn c language, encountered such a situation very meng, autistic!

CodePudding user response:

Someone, and a big help me have a look

CodePudding user response:

Send an error message and have a look

CodePudding user response:

All the class

Gaicheng

Class1

Chinese input doesn 't last come out.

CodePudding user response:

Chinese input method is finally out

Had been not to come out

The class is a c + + keyword

All the class to class1 or something

CodePudding user response:

Don't have to use what define, haven't to this stage, with const first, simplify the procedure absolute, oneself is to understand the

Bosses, but after a change or not is to run after the data is entered, but not output any results

CodePudding user response:

Bosses after input the data with the card, digital input is not enough, nor the output, is it because my program to write wrong?

CodePudding user response:

refer to 2 floor don't know what kind of name, reply:

send a error message see

Send the bosses

CodePudding user response:

Do you require every division average

Or

Each student average

Ah

?

CodePudding user response:

It feels like is for every division

Every division average, who helped me to see!
