CodePudding user response:

Qaq you trouble yourself non-computer majors to debug the code a little unfamiliar with the

CodePudding user response:

The last line fprintf was written by you?

CodePudding user response:

Simple - Soft references 2 floor response:

is the last line fprintf you wrote?

The teacher PDF source program

CodePudding user response:

Simple - Soft references 2 floor response:

is the last line fprintf you wrote?

Comments too seems to be no problem

CodePudding user response:

Can put the wrong information to complete

CodePudding user response:

Simple reference 5 floor - Soft reply:

can complete the error information to

Is this a mistake qaq

CodePudding user response:

The last line to remove ah, should do

CodePudding user response:

reference 7 floor is Simple - Soft reply:

the last line to remove ah, should be done

Tried not to see other examples like array has a problem

CodePudding user response:

So you have complete the error screenshot
