LIST OF FREQUENTLY ASKED QUESTIONS

1. How do you decide which integer type to use?2.

What should the 64-bit type on new, 64-bit machines be?

3. What can I safely assume about the initial values of variables which4. are not explicitly initialized? If global variables start out as ``zero,''5. is that good enough for null pointers and floating-point zeroes?6. How can I read a single character from the keyboard without7. waiting for a newline8. How can I copy a float into a string?9. Why doesn't C have an exponentiation operator?10.Why does everyone say not to use gets()?11.Why doesn't the code work? a[i] = i++;12.How does struct passing and returning work?13.Why can't you compare structs?14.How do I enter values using hexadecimal?15.What does extern mean in a function declaration?16.How do I ``get'' a null statement in my programs? I had the definition in one source file,

and in another I char a[6]

17.declared . Why did it work?18.extern char a[]19.why are array and pointer declarations interchangeable as function20.formal parameters?21.what is the difference between arrays and pointers?22.How does free() know how many bytes to free?23.How can I get the numeric (character set) value corresponding to a24.character, or vice versa?25.What is the right type to use for boolean values in C? Why isn't it a26.standard type? Should s or s be used for the true and false #define enum27.values?


26/26

28.What is the ``ANSI C Standard?''29.What's the difference between ``char const *p'' and ``char * const30.p''?31.What's wrong with this code:32.char c;33.while((c = getchar()) != EOF)...34.How can I print a ``%'' character in a printf format string?35.Which is larger, ``2'' or ``2.0''?
