The identifier varies in its address value for some variables. As with any other variation or continuation, you must announce the index before working with it in C ++. Points to identify the same type of data (such as an int or thread) of the same type, and are created with the help of a * operator. A dynamic address address is provided for the identifier. The most common type of dynamic detection is approx
type * var-name;
Here, type the default type of cursor and Must be a valid type of C ++, the word var is different from the cursor. The asterisk you used to declare the index is the same star used for duplication. The asterisk operator (*) helps us to retrieve the amount stored in the memory address. However, in this statement the asterisk is used to build solid as a reference. The following is the declaration of valid identifier -

char * ch1;
chart ch2 = 'a';
ch1 = & ch2;

If we have a variation named ch1, which is kept at 0x234 and retains the value 'a'. Active operator (&) will return 0x234. An unused user (*) will return the 'a'. Here, the ch2 address is given the ch1 index. To find the value stored in that address, use * ch1.
The actual data type of the total value of all references, whether whole, float, character, or otherwise, is the same, long hexadecimal number representing the memory address. The only difference between the different types of data indicators is the type of data that is variable or regularly displayed on the identifier.
