I am now clear that we can save memory by dynamic allocation of memory by the example of array declaration. I would like to know more about 'vector' data type . Can you please send me a link or suggest any source to get more knowledge on C++.

I also doubt one more yhing that while declaring a pointer we allocate a memory location i.e we allocate the same amount of memory as the one to which yhe pointer points . So this means that we initially allocate memory for the pointer then again go for dynamic declaration of another variable...

Can you give me an example where I need to use pointer Just the example without any code.

Can anyone help me understand the basic use of pointers. I am aware of pointers,yet I feel that a program can be made more easier without using a pointer. My basic dout is that can pointers be used to save memory by dynamic declaration of variables. I thought over it but found that using...

how about using two arrays one for the student ID and one for the score Then bubble sort the scores Arrange student IDs then finally group them.

how about finding reverse of a no by this logic and comparing it to the orignal one int sum,a,b; sum=0; cin>>a; b=a; while(a!=0) { sum=(sum*10)+(a%10); a=a/10; } if(sum==b) count<<"palindrome";

what is the use of the pow() function please specify another method just find reverse of a no and compare it to the orignal no

The answer is n+1 times The hint lies in the fact The nth differential of f(X)=x^n gives a constant And n+1th diffrential i.e of a constant gives us Zero
