Dynamic Memory Allocation. In this tutorial we will learn to store strings using pointers in C programming language. Creating a string In the following example we are creating a string str using char character array of size 6. Each character in the string str takes 1 byte of memory space. Creating a pointer for the string The variable name of the string str holds the address of the first element of the array i. In the above image the string "Hello" is saved in the memory location to Array of strings We can create a two dimensional array and save multiple strings in it.

For example, in the given code we are storing 4 cities name in a string array city. We can save those unused memory spaces by using pointers as shown below. We can represent the array of pointers as follows. The above array of pointers can be represented in memory as follows.
