The O/P in this question is not compiler dependant. The language specification of C clearly states that the arguments to the function are supposed to be passed from right to left. So irrespective of the compiler there should be only 1 answer20, 9, 19, 10

This is supposed to be same in both C and C++. According to ISO ANSII standard the answer to this is "undefined".

C program to count numbers of positive and negative numbers
Write a C program using arrays to count the numbers of positive and negative numbers which accepts the inputs as "size of the array" & "elements of the array" and outputs as "number of negative numbers in an array are" & "numbers of positive numbers in an array are" ?

Line 6 defines a variable-length array, which is only valid for C99 or later. The size of a VLA is not known until runtime, they may not declared static or extern, and only ordinary identifiers ...

In C99, the differences are that b is defined, rather than a, and that b is a variable-length-array rather than a conventional array.In C90, the sixth line is an error, as C90 does not support VLAs.
Garbage Value
In C if a variable is not assigned a value then why does it take garbage value?
Array is an lvalue or not?
An lvalue was defined as an expression to which a value can be assigned. Is an array an expression to which we can assign a value? The answer to this question is no, because an array is composed of several separate array elements that cannot be treated as a whole for assignment purposes. The following statement is therefore illegal: int x[5], y[5]; x = y; Additionally, you might want to copy the whole...

What is a static function?
A static function is a function whose scope is limited to the current source file. Scope refers to the visibility of a function or variable. If the function or variable is visible outside of the current source file, it is said to have global, or external, scope. If the function or variable is not visible outside of the current source file, it is said to have local, or static, scope.

With in the module it will comes upto end of the program.we can't access in another module.Number of functions it can access the static variable and sustaining that variable value.It can be declared as Local and Global.

Suppose void a(){} is defined in file1.c. If you declare it extern in file2.c then you can use it in file2.c. So its scope in not within file1.c. But if you declare it as static in file1.c then it can not be used in any other file.
