In C Dynamic Memory Allocation, memory is allocated at a run time. Dynamic memory allocation permits to manipulate strings and arrays whose size is flexible and can be changed anytime in your program. It is required when you have no idea how much memory a particular structure is going to occupy.

free() returns memory to the O/S. malloc() - used for general storage  o Will they point to already allocated memory (what we've seen so far)? o Will new memory need to be allocated (we haven't seen this yet)? char c; int array[10]; . Following is a simple example demonstrating dynamic memory allocation in single-dimensional arrays. Dynamically Allocate Memory for 1D Array in C++. Allocated space is uninitialized (random garbage).

Other terms like Runtime memory allocation can also be used for Dynamic Memory allocation. In C programming language, when we want to create a program where the data is dynamic in nature, i.e. the number of data items keeps changing during the execution of the program, we can use dynamic data structures in conjunction with dynamic memory allocation methods to handle the program more easily and effectively. Dynamic Memory Allocation Examples using C programs 1) C program to create memory for int, char and float variable at run time.. In this program we will create memory for int, char and float variables at run time using malloc() function and before exiting the program we will release the memory allocated at run time by using free() function.
