{
int f(int);

In above code there is function definition before function prototype declaration? Is it correct?.

Please explain how the prototype of a function is redeclared in main again.

1. Actually function is declared only once inside the main().
2. Before the main() here we defined the function.
3. An function can be declared anywhere in the program with one condition that it is declared (i.e. Give prototype) before calling.
Here function is declared inside the main but following the above condition that declaration is before calling.
We can't declare an function after the calling which will give you error as function should have a prototype.

@Ganesh.
You are wrong. Because program execution always starts with main. So it considered first the declaration.

@All.
Actually, the program is correct, if normal if statements are used.
First starts the main () then checks the func declaration. Then proceeds and passes the arg. And do such things and terminates.
