yes we can pass arguments if we pass argument ir would become commandline argument.
eventhough static and constant variable are common for alla objects the value of static variable can be increased in time being but it cannot be increased in constant variablejbode

One thing allowed by C that is *not* allowed by C++ is for main() to be called from within the program itself. IOW, in C, it's possible for main() to be recursive. The main() function in both C ...

Let's understand this by going through the following code
#include<stdio.h>
int f1();
int f2();
void main()
{
printf("%dt%d",f1(),f2());
}int f1()
{
printf("f1() enteredn");
return 4;
}
int f2()
{
printf("f2() enteredn");
return 5;
}
O/P-
f2() entered
f1() entered
4 5
we can conclude f2() is 1st executed
then f1() and in the end printf().hence we can say the precedence of execution of functions are from right to left.geek Jack

printf();then f2()then f1()then again printf() to print the value in f1 f2 these are arguments to printf function.

What is a const pointer?

Editorial / Best Answer
Answered by: Prasad

Constant pointer is NOT pointer to constant. Constant pointer means the pointer is constant. For eg:
Constant Pointer
int * const ptr2 indicates that? ptr2 is a pointer which is constant. This means that ptr2 cannot be made to point to another integer. However the integer pointed by ptr2 can be changed.
Where as a Pointer to constant is
const int * ptr1 indicates that ptr1 is a pointer that points to a constant integer. The integer is constant and cannot be changed. However, the pointer ptr1 can be made to point to some other integer.Jegan Chakkravarthy
- Jan 7th, 2011
An ordinary pointer variable preceeded with the "const" modifier. This prevents the value initialised from getting changed.

0 0 1 3 1Explanation :Logical operations always give a result of 1 or 0 . And also the logical AND (&&) operator has higher priority over the logical OR (||) operator. So the expression ‘i++ && j++ && k++’ is executed first. The result of this expression is 0 (-1 && -1 && 0 = 0). Now the expression is 0 || 2 which evaluates to 1 (because OR operator always gives 1 except for ‘0 || 0’ combination-...

Reallocating memory
When reallocating memory if any other pointers point into same piece of memory do you have to readjust these pointers or do they get readjusted automatically?
abhimanipal
- Jul 4th, 2009
If any pointers are pointing to the old memory location they have to be adjusted. C won't do it for you
alokag
- Jun 25th, 2009
While reallocating, there is no readjustments. The OS will just search for the required memory block(not in use) & if available pass its pointer to the user.Nb: It CAN be the same pointer you have before reallocation.

What is an lvalue?
An lvalue is an expression to which a value can be assigned. The lvalue expression is located on the left side of an assignment statement, whereas an rvalue is located on the right side of an assignment statement. Each assignment statement must have an lvalue and an rvalue. The lvalue expression must reference a storable variable in memory. It cannot be a constant.

- Apr 5th, 2008
Lvalue is is a memory location,whose value is not constant i.e it's value is changed when a new value entered into that location.And also it can be say as, it is an expression,where left side we have an identifier and right side(rvalue) the value.
