Beauty of Life

 One of my best shot

 Cola

 Sunset in Singapore

Some more PICS 

Beauty of nature is irresistible. Of all the beauty nature has, flowers got the most of it 

Some of the pics I have taken

Well I am not a professional photographer. Not even close to a good photographer. But I am going to share some pics I have taken. All the copyrights for this pics belongs to me alone.

After all Joy of happiness is in sharing it.

A cool evening, empty road and miles ahead left to explore...

Flow of a river...

Tricky, generic function pointer

#include
/* This is our generic function pointer */
typedef void (*fp)(void);
int func1(int a)
{
printf("Inside Func 1. Received %d\n", a);
return 2;
}

char func2(char b)
{
printf("Inside Func 2. Received %c\n", b);
return 'b';
}

int main()
{
fp ptr1;
int temp1;
char temp2;

ptr1 = (fp) func1;

temp1 = ((int (*)(int)) ptr1)(1);
ptr1 = (fp) func2;
// ptr1('g');
temp2 = ((char (*)(char))ptr1)('a');
printf("Inside Main. Received %d %c\n", temp1, temp2);
return 0;
}

Passing a function pointer to a function

#include

int any_function(int(*pfun)(int, int), int x, int y){
return pfun(x, y);
}

int sum(int x, int y){
return x + y;
}

int product(int x, int y){
return x * y;
}

int difference(int x, int y){
return x - y;
}

int main(void){
int a = 10;
int b = 5;
int result = 0;
int (*pf)(int, int) = sum; /* Pointer to sum function */

result = any_function(pf, a, b);
printf("\nresult = %d", result );

result = any_function(product,a, b);
printf("\nresult = %d", result );

printf("\nresult = %d\n", any_function(difference, a, b));
return 0;
}
