can someone pls tell me where I am wrong?

now the output shows the desired city first with the rainfalls .... but for some reason is showing the other cities and the symbols

You need to seriously rework the way you are reading that file... Look at fgets() and sscanf() ... the way you're doing it now you are printing stuff before you even know what it is.
