All examples in "C Programming Language" use commands getchar() and putchar().

What file do those commands put things into and take things out of?

Many things from that book have to be modified to cause no error in a modern
MS VC++ Express Edition compiler, using modern standart C library.

If I use a function is declared Int functionname (a,b,c) and I call it as
long at some point functionname (a,b,c)
would this change the type of value it returns?

If array variable appears as s[] in some function, what does the program refer to?
