Initialisation can be done in the following way.

func(int a,int b);
*pfunc(int a, int b);
main()
{

/*here the starting address of the function can be assigned
to a function pointer of the same type*/
pfunc = func;
....
....
....
}
func(int a, int b)
{
....
....
....
}

Answer / preeti singh

for e.g. if we have to declare a pointer to a function , the
signature of which is :
int add(int a,int b)

then a pointer to the above function can be declared as:
int (*myptr)(int ,int);

here myptr is a pointer which can point to any function that
takes 2 int args and returns an int value.

Answer / vadivel t

Sorry the above function pointer declaration should be like
this

(*pfunc)(int, int);

main() { int a,b; printf("%d,%d",scanf("%d%d",&a,&b)); } => do u mean above program's output... =>output will be:2,whatever you enter value for b. =>because scanf is a library fn which will return how many arguements it processes, and second value you are right mr.Satya but i found my self unable to understand that for the first time scanf returns the no of successful matches but how for the second time it returns the value of 'b'.while a function should return the same 'r' value every time.
