Program not displaying anything after compiling in c - c

Question

I made a C program to keep track of the distanced traveled by buses and hours worked by employees, both have ID as the primary key, these save on 2 different files. The code compiles but does not show anything, care to help? I used different sources for help with this code but I don't think that's the problem since a similar code runs well

Answer 1

Thank you for all your help, the first problem was with scanf which I did not see so thank you for pointing it out and the other is the first 3 lines of main, the int el = 0; emp eplist[SIZE];and readfile(&el, eplist); were not supposed to be in this function.
