Answer 1

modify the program using dynamically initialized variable.....

Answer 2

SoloLearn asks for input before the program starts. So your while 1 keeps repeating the software, even if there is no input anymore. This probably is causing an overflow somewhere, probably at the stack, in which throws the segfault you are looking for. I recommend not using while 1, but a validation condition
