11. Pointers in C++ | Guaranteed Placement Course

[@galax5130]

My Rules of understanding pointers:- '&' - this will return an address of any variable or things. '*' - this will dereference an address 'int *' - this will make a pointer variable 'variable_name' - this will return value of a 'variable_name' Extra:- swap(a,b) - Call by value swap(&a,&b) - Call by reference

char* can also make pointer variable.

[@degenerateweeb1510]

So Jab tum address ko baghaoge i.e. *a++ karoge toh tumhara address next jagah par point karega jaha par kuch nahi hai. and jab tum *a+=1 karte ho tab address nahi increment hota hai, tab a par joh element hai usme 1 add hota hai! bcz jab hum *a++ karte hai tab memory address +2 se badhta hai, and jab hum *a+=1 karte hai tab woh element me 1 add hota hai.

The point is we can't increment the pointer directly as *a++; It'll still print a=2 but using (*a)++; gives the incremented value It is somewhat similar to BODMAS rule. We need to dereference the pointer a then increment it Thank me later!

[@atharvagarwal5367]

The point is we can't increment the pointer directly as *a++; It'll still print a=2 but using (*a)++; gives the incremented value. *a++ - Post Increment Operator, it first assigns the value and then increases the value later on. If we use ++*a - Pre Increament Operator, then it increase the value first and then assigns the value later on. So on using ++(*a) will give you the correct answer. Thanks !!

[@sourabhjain8102]

If anyone is facing any problem, this can be because ++ has equal precedence with the * and the associativity is right-to-left. You can use ++*a or (*a)++ to specify the order of evaluation.

Those pointers are containing the addresses of variables, so whether you pass addresses or pass pointers itself since an indirection operator is used so there is no problem.
