End of Line refers to the 'n'( new line character). It will perform operations till it come across 'n'. EOF refers to End of File. It is the last character in the file.(if it is not empty). If the file is empty then only EOF will be present.Some compilers give its value as -1.

Both the malloc() and the calloc() functions are used to allocate dynamic memory. Each operates slightly different from the other. malloc() takes a size and returns a pointer to a chunk of memory at least that big:  void *malloc( size_t size ); calloc() takes a number of elements, and the size of each, and returns a pointer to a chunk of memory at least big enough to hold them all: void *calloc(...

Malloc() and calloc() are used to allocate memory blocks dynamically.malloc() is a bit faster since it does not initialize the allocated memory blocks to as it is done by calloc() function.Hence it is better to use malloc() then calloc().

If you declare a variable, its name is a direct reference to its value. If you have a pointer to a variable, or any other object in memory, you have an indirect reference to its value.

For integral types, on a machine that uses two’s complement arithmetic (which is just about any machine you’re likely to use), a signed type can hold numbers from –2(number of bits – 1) to +2(number of bits – 1) – 1. An unsigned type can hold values from 0 to +2(number of bits) – 1. For instance, a 16-bit signed integer can hold numbers from –2^15 (–32768) to +2^15 – 1 (32767).

we know that C is not platform independent.but if we make a program on a operating system and copy the same program on other os without any changes then this program will run after compiling and will give the same answer.
so if same program will run on other os then why C is not platform independent.

C is not platform dependent because it does not generate the uniform executables.
suppose if we have build C code and generated binary in Windows and this same binary will not work on Linux.

Why integer range -32768 to 32768 and actual meaning of storage size 2 bytes ?

jbode

 Profile Answers by jbode Questions by jbode

• May 28th, 2012

[-32767,32767] is the minimum range for int, meaning a minimum size of 16 bits. Implementations may choose a wider size and range for integers.

That range covers most architectures, whether ones or twos complement.

Varun Pratap Singh

In C language, int takes 2 bytes. Now 2 bytes mean 16 bits. One bit out of these 16 bits is for sign (+ or -) of integer. So, remaining 15 bits will store data in form of 0 and 1. The maximum value in...
