What is dynamic memory allocation in C++?Allocating memory at compile timeAutomatically managing memoryAllocating memory during runtimeIncreasing the size of the stack

Dynamic memory allocation in C++ refers to the process of allocating memory during runtime. In other words, it is the process of allocating memory space for variables or data structures at the time of execution or runtime of the program. This is done using certain functions like malloc(), calloc(), realloc() and free() which are part of the C++ standard library. This is different from static memory allocation where the memory needs to be allocated at compile time. Dynamic memory allocation allows your C++ program to adapt to varying memory requirements, making it more flexible and efficient.
