 ## Addresses in C
 Before we get to the definition of pointers, let us understand what happens when we write the following code:

+# Changing Value Pointed by Pointers
+Let's take an example.
+```c
+int* pc, c; 
+c = 5; 
+pc = &c; 
+c = 1; 
+printf("%d", c); // Output: 1 
+printf("%d", *pc); // Ouptut: 1

+We have assigned the address of c to the pc pointer.
+
+Then, we changed the value of c to 1. Since pc and the address of c is the same, *pc gives us 1.

+We have assigned the address of c to the pc pointer.
+
+Then, we changed *pc to 1 using *pc = 1;. Since pc and the address of c is the same, c will be equal to 1.
