Few rules about C pointers 1) A pointer variable does not store value directly just like int, float variables. A pointer store only reference (memory address) of another variable. Consider the following code intx=100;int*ptr;ptr=&x; ...
Although a lot of programming can be done without the use of pointers, their usage enhances the capability of the language to manipulate data. Pointers are also used for accessing array elements, passing arrays and strings to functions, creating data structures such as linked lists, trees, graphs...

This assumption is valid for array members. By definition, an array is a series of values of the same type; its elements reside in contiguous memory locations. However, storage for any types except array elements is not guaranteed to be filled by the same type of identifiers. That is, blan...
I wonder if I can output the address of a pointer or transfer it to a integer. BlaiseDeng You can, but need unsigned long long on a 64-bit machine. #include<iostream>intmain(){int*i=newint(1);*i=12345;unsignedlonglongaddress=(unsignedlonglong)&i;std::cout<<&i<<" "<<std::hex...
