Why my code does not work correctly?

Question

https://code.sololearn.com/cK6PHsdXeRl4/?ref=app when I run the code, only the text is displayed before the value of the variable is entered. in other compilers the program works correctly. sorry for bad english. :(

Answer 1

ok now I found it in line 23:
(*ptrnumber)%i) causes the error
if your intention was to convert it to an int try
int(*ptrnumber)
changing this will make it work

Answer 2

thanks all for answers, I really did not notice the division by zero
