It is impossible for my PC to compile a source code of C on Netbeans even though it has no syntax error.(Netbeans is a software that provides a function of editor and display of programming)
The source cord can be compiled on command prompt.
I guess the reason is......The environment , setting of NB or the place it is saved in
I am not used to programming, but I will keep trying even if I see many errors.
Eventually, Nilas fixed it by changing the compiler and some manipulation.
That is so kind of him.
