Please eldest brother of the two days going to cry

CodePudding user response:

You want to open a few times
A file, only leave a fopen

CodePudding user response:

Code is too messy, format is not clear, I don't copy to adjust the format I couldn't see the compiler, the error is very much also, you want the nr and rq should be one to write one to read it, you should write the date on which the rq, nr content, in so doing, there is no necessary to make structure, the output is similar; The fscanf (op, "% s \ n", & amp; Nr); This statement to read string to a structure is this? Find () function in the while (1) loop inside put two break is what circumstance? Executed only once, do not have to use the while, while to break with generally want to combine the if statement, meet certain conditions to jump out, you put directly under the while loop of two break, saw the first jump out, behind a piece of code that is never executed, is to remove the first just to perform again break, is equal to the order

CodePudding user response:

Facing the day in the main file only write the date, other are written into the content of the
Fprintf (fp, "% s \ n", rq, day);
The fprintf (lp, "% s \ n", nr. Wen);
Find inside, date from the date of the file and read, read again, this is obviously not matching
The fscanf (op, "% s \ n", & amp; Rq. Day); }
The fscanf (op, "% s \ n", & amp; Nr);
