Re: [algogeeks] C o/p adobe
For Dev-C++, you have to include one file in another.
So either add *#include file1.c *in file2.c and compile file2.c or
add *#include
file2.c *in file1.c and compile file1.c.
Hope this helps.

By default, the declaration and definition of a C function have
“extern” prepended with them. It means even though we don’t use
extern with
the declaration/definition of C functions, it is present there. For
example, when we write.
int foo(int arg1, char arg2);
There’s an extern present in the beginning which is hidden and the
compiler treats it as below.
extern int foo(int arg1, char arg2);

Re: [algogeeks] C o/p adobe
Think it this way
If you are compiling only one file in which you have declared variable as
intern, where would compiler find its actual definition because you are *not
compiling *the second file.
*file1.c : file in which variable is defined*
*file2.c : file in which variable is declared as extern*
When you compile both the files together, as compiler sees *extern
*declaration,
it will check if you have defined that variable somewhere. It will only
check files that are being compiled*. So if you are not compiling *file1.c *it
will not check that file. That's why you have to compile both the files
together.
In simple words, what extern does is that it checks if you have defined
that variable somewhere* in the code that is *being compiled. *
Try following codes
*//start of code*
*#includestdio.h*
*main() {*
*extern int i;*
*printf(i = %d, i);*
*return 0;*
*}*
*//end of code*
It will show you an error that variable i has not been defined anywhere in
the file.
*//start of code*
*#includestdio.h*
*main() {*
*extern int i;*
*printf(i = %d, i);*
*return 0;*
*}*
*int i = 7;*
*// end of code*
Try above code, it will run and show you the correct result. Your codes are
doing precisely the same thing.
*#include file1.c* or *#include file2.c* was based on the same idea.
*scope rules apply.
Some lines of *the* book The C Programming Language by Dennis Ritchie:
There must be only one definition of an external variable among all the
files that make up the
source program; other files may contain extern declarations to access it.
(There may also be
extern declarations in the file containing the definition.) Array sizes
must be specified with
the definition, but are optional with an extern declaration.

Try following codes

By default, the declaration and definition of a C function have
“extern” prepended with them. It means even though we don’t use extern
with
the declaration/definition of C functions, it is present there. For
example, when we write.
int foo(int arg1, char arg2);
There’s an extern present in the beginning which is hidden and the
compiler treats it as below.
extern int foo(int arg1, char arg2);

By default, the declaration and definition of a C function have
“extern” prepended with them. It means even though we don’t use extern
with
the declaration/definition of C functions, it is present there. For
example, when we write.
int foo(int arg1, char arg2);
There’s an extern present in the beginning which is hidden and the
compiler treats it as below.
extern int foo(int arg1, char arg2);

Re: [algogeeks] C o/p
int i=5; i=++i/i++; print i; i=1 coz ++ operator in c has preference from right to left, therefor first (i++ is ca;cu;ated) i=5 is used then it's incremented ie i=6 now. Now at this point of time ++i is calculated, which makes i=7; finally / operator is performed and i=7/5 is calculated, which makes i=1. Similarly, int b=a++*a--; can be calculated using the preference rule. On Mon, Jul 9, 2012 at 12:16 PM, rahul sharma rahul23111...@gmail.comwrote: what about post increment??

Re: [algogeeks] C o/p
Firstly, this is ambiguous and expressions with multiple increment/decrement operators will get executed according to the compiler. Even if you consider the normal way, as we(humans) percieve it, it will be evaluated as (++i)/(i++), which is 6/5, which is 1. Simple!

Re: [algogeeks] C o/p
it violates sequence pt. rule..so output is compiler dependent , but as there is Lvalue error it would compile fine. but in prev case pre decrement expects Lvalue but has r-value instead bcoz of the post increment.

Re: [algogeeks] C o/p help
output depends on sizeof(int)so it may be different if you run on
different compilers.
considering *sizeof(int) = 2;*
argv[] is array of pointers.
(p+=sizeof(int))[-1];
p=p+2 // 2=sizeof(int);
now p will be pointing at index *argv[2];
then you are doing
p=p-1;
i.e p will point to *argv[1]
hence output will be
o/p = cd
