My programme is about a ticket system, I can compile and run with help of a nice person, but it is strange that when I have the first choice and the programme will print the message and have no response at all:
"Please merge the segments toger eg. type Bei Jing as Beijing"
The programme contains 4 files:
fatal.h fatal erros
tree.h tree header file
tree.c tree implementation file
project.c main file
