by doing next:

int *calcSum(char *, char *);
int *calcSum(char *one, char *two) { // Whats difference between * front of function name
/* Does it mean i use *one for value, or i use just one?
 if i use one, i have no change to get address of one?
now when doing
*/
return one + two;
/* It should return answer not sum'ed addresses */

}

int a = (b = 1);

int answer = calcSum(a,b);
