C++ Pointers

Creating Pointers

You learned from the previous chapter, that we can get the memory address of a variable by using the & operator:

Example

string food = "Pizza"; // A food variable of type string

cout << food;  // Outputs the value of food (Pizza)
cout << &food; // Outputs the memory address of food (0x6dfed4)

A pointer however, is a variable that stores the memory address as its value.

A pointer variable points to a data type (like int or string) of the same type, and is created with the * operator. The address of the variable you’re working with is assigned to the pointer: Continue reading C++ Pointers

Creating Pointers

You learned from the previous chapter, that we can get the memory address of a variable with the reference operator &:

Example

int myAge = 43; // an int variable

printf("%d", myAge);  // Outputs the value of myAge (43)
printf("%p", &myAge); // Outputs the memory address of myAge (0x7ffe5367e044)

A pointer is a variable that stores the memory address of another variable as its value.

A pointer variable points to a data type (like int) of the same type, and is created with the * operator. Continue reading C Pointers
