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
any data type with star will make a pointer variable which can be used to address a memory location containing data of same data type as pointer@@herohera3497
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!

brother you are absolutely right, but also try to understand that if you are an absolute beginner, then did you understand? a big NO, so that's why some beginners didn't liking it!
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.
In my opinion, you're the best teacher on Apna College! ( No offense to other teachers, everyone's doing a great job, it's just my personal opinion, I am a slow learner)
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 !!
I apologize for any confusion, but the program you provided is an example of 'pass by address,' not 'pass by reference,' as it's important to use the correct terminology in programming.
No you can't use *ptr = &a as it is different. In Int *ptr , *ptr is no a variable only ptr is a variable. U can also write it as int** ptr. Int* is not integer data type, it is a integer type data type for storing address of a int variable.
A much simpler approach #include using namespace std; void swap(int& a, int& b){ int temp = a; a=b; b=temp; } int main() { int a=2; int b=4; swap(a,b); cout
Program to Increment variable using Pointers:- #include using namespace std; void increment(int *a){ (*a)++; } int main(){ int a=2; increment(&a); cout
*Program to Increment variable using Pointers: #include using namespace std; void increment(int *x); int main() { int x = 2; increment(&x); //Pass by Reference cout
One more easy Way to call #include using namespace std; void Swap(int &a,int &b){ int temp = a; a = b; b = temp; } int main(){ int a = 3, b = 5; Swap(a, b); cout
We can't directly increment *a++ because it follows bodmas rule. Here ++ has more precedence than * operator, So it does not update the value. To update the value the use (*a)++ .😀😀

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
