What is dynamic memory allocation in C Language?

  • In case of dynamic memory allocation, memory is allocated at runtime and memory can be increased while executing the program. It is used in the linked list.
  • The malloc() or calloc() function is required to allocate the memory at the runtime.
  • An allocation or deallocation of memory is done at the execution time of a program.
  • No dynamic pointers are required to access the memory.
  • The dynamic memory is implemented using data segments.
  • Less memory space is required to store the variable.
  1. For example
  2. int *p= malloc(sizeof(int)*10);


The above example allocates the memory at runtime.
