What is the data type of pointer variables? Suppose that we don‘t know the name of a variable but we do know its address. Can we access the contents of that variable? Explain briefly.   Subject: C++

Question 1  I need help modifying the code below to store the variable's memory address in a pointer variable. Then using only the pointer variable to print the variable's address and value.  Full explain this question and text typing work only thanks
