Yes. A header file will provide information about "prototype of an exported function(probably from other modules)", "exported variables (extern)", "macros", "functions bodies for static inline functions", etc. basically none of them will allocate a memory by itself. The below code will work very fineint printf(const char *fmt, ...);unsigned int strlen(const char *str);int main(){ char *s = "Hello World"; printf ("String s [%s] has %d characters in it.n", s, strlen(s)); return 0;}

Yes, In linux (GCC Compiler) we can write a C program without #include. But for special header files which are not part of C standard library, we may have to include the headers.

you need not write #include, but at the time of compilation you need to compile with options which direct compiler to include files in the provided directory. in gcc it is done by -I option.
