C Memory Address

---

• When a variable is created in C, a memory address is assigned to the variable.
  • The memory address is the location of where the variable is stored on the computer.
• When we assign a value to the variable, it is stored in this memory address.

How to access the memory address of a variable

To access it, use the reference operator (&), and the result represents where the variable is stored:

Example:

int myAge = 43;  
printf("%p", &myAge); // Outputs 0x7ffe5367e044

Note:

The memory address is in hexadecimal form (0x..)

Note:

You should also note that myAge is often called a “pointer”. A pointer basically stores the memory address of a variable as its value. To print pointer values, we use the %p format specifier.
