Each pointer has a valueThe pointer is a non-negative integer value that represents the stored address.The pointer must have a typeThis type refers to the data type that the pointer points to this address cell (contiguous address space). Void

1. How to write a C + + programA. Each program can have only one main () function, and C + + programs are executed from the main () function.The b.class mechanism gives us an added level of abstraction within the program.C. The specific object cin

/* Read a piece of text into a vector object, each word stored as an element in the vector, * required to be implemented with an iterator that converts each word in the vector into uppercase letters. * Output converted elements, one line per 8 words

in C If the pointer is a basic numeric typeint, Foalt, long, etc., if the output hascout Where PTR is the name of the pointer, the output value is the address of the pointer,If it is a char * (char pointer), the value of the char pointer is output.
